Proceedings of the United States National Museum
a Proceedings of the United States National Museum SMITHSONIAN INSTITUTION • WASHINGTON, D.C. Volume 121 1967 Number 3579 VALID ZOOLOGICAL NAMES OF THE PORTLAND CATALOGUE By Harald a. Rehder Research Curator, Division of Mollusks Introduction An outstanding patroness of the arts and sciences in eighteenth- century England was Lady Margaret Cavendish Bentinck, Duchess of Portland, wife of William, Second Duke of Portland. At Bulstrode in Buckinghamshire, magnificent summer residence of the Dukes of Portland, and in her London house in Whitehall, Lady Margaret— widow for the last 23 years of her life— entertained gentlemen in- terested in her extensive collection of natural history and objets d'art. Among these visitors were Sir Joseph Banks and Daniel Solander, pupil of Linnaeus. As her own particular interest was in conchology, she received from both of these men many specimens of shells gathered on Captain Cook's voyages. Apparently Solander spent considerable time working on the conchological collection, for his manuscript on descriptions of new shells was based largely on the "Portland Museum." When Lady Margaret died in 1785, her "Museum" was sold at auction. The task of preparing the collection for sale and compiling the sales catalogue fell to the Reverend John Lightfoot (1735-1788). For many years librarian and chaplain to the Duchess and scientif- 1 2 PROCEEDINGS OF THE NATIONAL MUSEUM vol. 121 ically inclined with a special leaning toward botany and conchology, he was well acquainted with the collection. It is not surprising he went to considerable trouble to give names and figure references to so many of the mollusks and other invertebrates that he listed. -

The stem group from which the Latrogastropoda originated lived during or shortly before Aptian/Albian time (100–125 Ma). Several groups of Latrogastropoda that lived at the time of deposition of the Campanian to Maastrichtian (65–83 Ma) Ripley Formation have no recognized living counterparts. These Late Cretaceous species include the Sarganoidea, with the families Sarganidae, Weeksiidae and Moreidae, which have a rounded and low protoconch with a large embryonic whorl. -

RESUMEN Con el objetivo de determinar el grado de impacto de la depredación del caracol Melongena melongena sobre el ostión Cmwostma vitginica se realizó una investigación en la Laguna de Tampamachoco, cerca de la ciudad de Tuxpan, Veracruz. Los resultados indican que la densidad del caracol en la zona de estudio es de 0.0007 individuos/m2, mientras que si sólo consideramos los cuadrantes en la zona de distribución preferencial es de 0.00437 individuos/m2. El caracol habita en todos los sustratos muestreados, pero se encuentra preferentementeen la zona y tipo de sustrato que prefiere el ostión, y su dieta incluye en proporción apreciable a la ostra (28%). La importancia de la depredación por caracoles, como causa de muerte no es de consideración debido a que la densidad de población de Melongena melongena es muy baja. -

The aim of the present study was to describe the radula of 2 Pugilina cochlidium populations using SEM. The radula in 2 species proves itself as a rachiglossate type showing the radular formula of 1 + R + 1. The first population hasthe central tooth wide with sharp cusps equal in length, emanate from posterior margin of tooth base. The lateral teeth have 2 cusps and are long, sharp, pointed and bent towards the rachidian tooth. Whereas the second population, the central tooth is narrow with sharp cusps equal in length, emanate from posterior margin of tooth base. The lateral teeth have 2 cusps and are broad, longer, sharp, pointed and bent towards the rachidian tooth. -

We present the Invertebrate allometry results of an experimental allometric study on Melongena corona snails collected from the mangrove dominated Marine shell shoreline of Weedon Island Preserve, Florida, USA. Our analysis produced regression constants for predicting tissue weight estimates from four independent linear shell metrics, including: length, aperture-length, height, and width. This study is unique in its integration of field and laboratory experimentation, and in the large sample size used to develop allometric constants. To exemplify the utility of our regression models, we apply our al- lometric constants to a late-Precolumbian (ca. 895–1268 CE) marine shell assemblage excavated from the Weeden Island site (8PI1), Pinellas County, Florida, USA. 1.

El sitio donde se extrae este organismo con mayor frecuencia es en la laguna de Chelem. Esta actividad se realiza de manera artesanal y sin restricción, siendo necesario realizar estudios biológicos y pesqueros para establecer una regulación adecuada. De enero a diciembre de 2000 se realizaron muestreos mensuales de M. corona bispinosa. Se midió la longitud de la concha y peso de los organismos; Se separaron 30 hembras y 30 machos adultos a los que se les extrajeron las partes blan- das. La gónada se separó para caracterizarla histológicamente, obteniéndose el ciclo reproductor. Se definieron cuatro esta- dos gonadales para ambos sexos; (I) inmaduros: los gametos no se pueden identificar. (II) Maduración: división celular acti- va, los gametos maduros pueden o no estar presentes. (III) Maduros: gametos en su mayoría maduros. (IV) Postcópula o postdesove: Los folículos se encuentran parcial o totalmente vacíos, con algunos gametos maduros y se observa la presencia de fagocitos dentro de los folículos. -

BAYER Melongena Schumacher, 1817 (= Galeodes Roding) Thiele (1931, p. 320) gives the name Galeodes (Bolten) Roding, 1798, to this genus. This name, however, was already used by Olivier in the En• cyclopedic methodique, Insectes (1791, vol. 6, p. 578) for a genus of the Solifugidae. The author gave a detailed diagnosis and, moreover, described two species of the genus. Galeodes Olivier, 1791, obtains therefore priority in respect to Galeodes Roding, 1798, and this last name must thus be dropped as a hononym. Cassidula "Humphrey" (1797, p. 32), which is sometimes used, is not valid, as according to Opinion 51 the anonymous catalogue "Museum Calonnianum,, "is not to be accepted as basis for any nomen- clatorial work". The next name to be considered for this genus is Melongena Schumacher, 1817. This author (1817, p. 212) gives a clear diagnosis of the genus and mentions as genotype M. fasciata [= M. melongena (L.)]. As in my previous catalogues I have, besides the species present in our collection, as far as possible, included here all the species of Melongena that are mentioned in literature. All the specimens from one collector in a certain locality, as far as they are kept dry, bear the same letter, whilst of the material preserved in liquor the number of the jar is given. In the list of species dealt with below, I have inserted these letters or numbers, followed by a number indicating how many specimens we possess from that locality. -

THE MIOCENE AND RECENT MOLLUSCA OF PANAMA BAY * BY CHIH CHANG Li lE ¿ INTRODUCTION The material studied has been in the Paleontogical collection, of Columbia University for several years.The label on the material reads as follows: "Brought up by marine dredge from depths varying from ro.. ft. to 4°. ft. in the mud at the mouth of the Rio Grande near La Boca about one mile from the mainland in Panama Bay."It was apparently collected by Mr. Donald F. Mac Donald in ro7, formly Geologist of the Canal Commission, and sent by him to Columbia University.The material has been partially identified by Dr. J. J. Galleway and Mr. S. W. Lowman in 1923.I discovered that this collection is a mixture of Lower Miocene and Recent shells, for the collector was unable to keep them separate under the circumstances. The faunas of the two horizons which are separated and the relative abundance of each species are as follows:- LOWER MIOCENE SPECIES i.A rca dariensis Brown and Piisbry a 2.Arco cf. pennefli Gabb r 3.Arca cf. piUceri Dali r 4.Arco (Scapharca) golfoyaguensis Maury r .
