Lionycteris spurrelli, Meso phylla ma cconnelli, Vampyressa brocki , Vampyrops brachycephalus, Rhogeessa tumida, Molossops abrasus, and M. greenha/li. Additional information is provided on several species of bats alrea dy known to occ ur in Suriname, including Micronycteris minuta , M . nicefori, Phylloderma stenops, Tonatia biden s, T. brasilien se , T. carrikeri, Ya mpyrum spectrum . Anoura caudifer, Caro/lia brevicauda , Rhinoph ylla pumilio, Vampyressa bidens, and Lasiurus ega. INTRODUCTION In his classical work, Hus son (1962) reported 58 species of bats as occurring in Suriname. In The Mammals of Suriname, Hu sson (1978) brought the number of species of bats to 60 (excluding Myotis suri­ nam ensis, see LaVal, 1973a). The total subsequently was raised to 70 by Genoways and Williams (1979). Finally, with the recent description Submitted for publi cation 28 December 1979. 213 214 ANNALSOF CARNEGIE MUSEUM VOL. 49 of Tonatia schulzi (Genoways and Williams , 1980), the chiropteran fau­ na, prior to the work described herein, consisted of 71 species. Our material resulted from fieldwork in Suriname that was con­ ducted primarily between 10 August and 9 October 1979, which re­ sulted in the collection of 960 specimens of bats representing approx­ imately 62 species. Fourteen of the se never have been reported from Suriname, although Husson (1978) speculated that four of the species probably occurred in the country. These new records are discussed below. Information also is provided for 12 other species of bats, all previously reported from Suriname, which adds significantly to data available in previous works (Husson, 1962, 1978; Genoways and Wil­ liams, 1979). The number of bat species known to occur in Suriname is now 85. METHODS AND MATERIALS All of our specimens, unless otherwise indicated, were captured in mist nets in the months of August , September, and October 1979, and were prepared as fluid-pre served specimens or as sta ndard museum skins accompanied by skulls. Supplimental data re­ corded for most of these specimens included standard karyot ypes, live tissue for chro­ mosomal banding, frozen tissue for electrophoretic analysis, and tissue for anatomical studies. The specimens are deposited in the Section of Mamm als of Carnegie Museum of Natural History and synoptic series will be returned to Suriname in care of STINASU for deposition in their refe rence collection. Forearm and cranial dimen sions were taken with dial calipers accurate to 0.1 rnrn . Unless otherwise indicated, all specimens are con sidered to be adults as indicated by completely fused phalangeal epiph yses. Measurements taken in this study included length of forearm , greatest length of skull, condylobasal length, zygomatic breadth, mastoid breadth, postorbital breadth, length of maxillary toothrow, and breadth across upper molars. Genoways and Williams (1979) have described how the se measurements are taken. Statistics presented in this study were calculated with a Texas Instruments SR-5IA calculator. Field weights in gram s were taken with Pesola spring scales. The reproductive con­ dition of skin/skull specimens was determined by gross disse ction in the field, whereas fluid-pre served specimens were dissected in the laboratory.Crown-rump length of fe­ tuses and testes lengths of males are given in millimeters. A CKNOWLEDGMENTS Our fieldwork in Surin ame in 1979 was supported by a grant from the Alcoa Foun­ dation , Charles L. Griswold, President. We gratefully acknowledge this support. Our fieldwork in 1977 was supported by the M. Graham Netting Research Fund through a grant from the Cordelia Scaife May Charitable Trust. We would like to thank Dr. Joop P. Schu lz and Henry A. Reichart, STINASU, for their assistance during our work and for making the many facilities of STINASU avail­ able to us. Without their help , our work in Surin ame would have been impos sible. Ferdinand L. J. Baal , Department of Forestry, issued our permits. Mr. Leo Roberts, STINASU, pro ved to be an excellent field guide and a most congenial companion. The personnel of Surinaams Museum of Natural History, parti cularly Marga Werkhoven, and Mr. I. Douglas, were helpful in making hous ing and laboratory facilit ies available for our use . Mr. E. W. Ken smil of the Airports and Civil Aviation was of great assistance in providing some of our air transportation to the country's interior. Dr. Robert Power 1980 W ILLIAMS AND GENOWAYS-B ATS FROM S URINA ME 215 of the Universi teit van Suriname ass isted in acquiring chemicals for our karyological studies. Rodney L. Honeycutt, Jane A. Groen , and Dr. Carleton J. Phillips assisted with the collection and preparation of specimens. Dr. Dilford C. Carter examined and verified the ident ification of our Vampyrops brachyceph alus, Dr. Karl F. Koopman made avail­ able to us comparative mate rial from the American Museum of Natural History. SPECIES ACCOUNTS Pteronotus personatus personatus (Wagner) Specimens examined (2).-NICKERtE: Grassalco, 4°46'N , 56°46'W, 2. Rem arks.-Our specimens of P. persona/u s are the first to be re­ ported from Suriname and confirm speculations of Husson (1962, 1978) that this species occurs in the country. Our records extend the known range of the species in South America about 700 km to the southeast. At the present time two species of Pteronotus are known to occur in Suriname-Po parnellii and P. persona/u s (Huss on, 1962, 1978; Gen­ oways and Williams, 1979). These spec ies are easily differentiated by size. Both specimens of P. personatus , a male and female , were collected between 2000 and 2030 hours on 7 September. The male weighed 8 and had testes that measured 5; the female weighed 9 and was not pregnant. The collecting locality was located along a small river, about 15 m wide , with many logs and boulders protruding from the surface of the water. The surrounding vegetation consi sted of secondary trop­ ical jungle and hardwood forest. Mist nets were set up in the vicinity ofthe Grassalco headquarters buildings, across the river in three areas, and along a trail that passed through a hardwood forest in which all undergrowth had been cleared . The trail was about 50 m from the river. Species of bats collected over the river with our specimens of P. personatus included Rh ynchonycteris naso , Noctilio leporinus , Anoura caudifer, Choeroniscus interm ediu s , Lonchoph ylla thom asi, Artibeus cinereus , two large species of A rtibeus (currently under in­ vestigat ion to determine taxonomic relationships), Chiroderma trini­ tatum , Vampyress a brocki , Vampyrops helleri, Myotis albescens, Mo­ lossops abrasus, M . gree nhalli, and Molossus molossus. Species collected in the adjacent forest included Pteronotu s parnellii, Tonatia bidens, An oura cau difer, Carollia brevicauda, C. perspicillata , two large species of Artibeus, and Sturnira lilium . We follow the review of the famil y Mormoopidae by Smith (1972) in using Pteronotus for the generic name of personatus instead of Chilonycteris, as was used by Husson (1962, 1978). The name Chilo­ nycteris is considered by Smith (1972) to be a subgenus of Pteronotus. The subspecies P. p. personatus has been reported pre viou sly from 216 ANNALS OF CARNEGIE M USEUM VO L. 49 Costa Rica, Pan ama, Colombia, Venezuela, and Trinidad (Smith, 1972). External and cranial measurements of our two specimens (male fol­ lowed by female) are as follows: length of forearm, 48.4 , 48.9; greatest length of skull , 16.2, 16.7; condylobasal length, 14.8, 15.2; zygomatic breadth, 9.0, 9.1; mastoid breadth, 8.7, 9.1; postorbital breadth, 3.5, 3.5; length of maxillary toothrow, 6.6, 6.1; breadth across upper mo­ lars, 6.2, 6.0.
