They capture prey with an adhesive net that is formed in a fraction of a second. The first naturalist to formally describe them was Lansdown Guilding (1797-1831), a British priest from the Caribbean island of Saint Vincent. His life is as little known as the history of the field he initiated, Onychophorology. This is the first general history of Onychophorology, which has been divided into half-century periods. The beginning, 1826-1879, was characterized by studies from former students of famous naturalists like Cuvier and von Baer. This generation included Milne-Edwards and Blanchard, and studies were done mostly in France, Britain, and Germany. In the 1880-1929 period, research was concentrated on anatomy, behavior, biogeography, and ecology; and it is in this period when Bouvier published his mammoth monograph.

Entomologie, Martin-Luther-King Pfalz 3, D-2000 Hamburg 13 Abstract: What is a modern monograph? The problem is tackled on the basis of a discussion of the compli- cated taxonomy of Onychophora. At first glance the phylum presents a very uniform phenotype, which led to the popular taxonomic use of the generic name "Peripatus" for all representatives of the group. The first description of an onychophoran, as an "aberrant mollusc", was published in 1826 by GUILDING: To date, about 100 species have been described, and Australian colleagues (BRISCOE & TAIT, in prep.), using al- lozyme electrophoretic techniques, have discovered large numbers of genetically isolated populations of as yet un- described Peripatopsidae. The taxonomic hislory is reviewed in brief. Following the principles of SIMPSON, MAYR, HENNIG and others, selected taxonomic characters are discussed and evaluated. Questions arise such as: how can the pioneer classification (sensu SEDGWICK, POCOCK, and BOUVIER) be improved? New approaches towards a modern monographic account are considered, including the use of SEM and TEM and biochemical methods.

THE PRESENT DISTRIBUTION OF THE ONYCHOPHORA, A GROUP OF TERRESTRIAL INVERTEBRATES. By AUSTIN H. CLARK CONTENTS Preface I The onychophores apparently an ancient type 2 The physical and ecological distribution of the onychophores 2 The thermal distribution of the onychophores 3 General features of the distribution of the onychophores 3 The distribution of the Peripatidae 5 Explanation of the distribution of the Peripatidae 5 The distribution of the American species of the Peripatidae 13 The distribution of the Peripatopsidae 17 The distribution of the species, genera and higher groups of the ony- chophores in detail 20 PREFACE A close study of the geographical distribution of almost any class of animals emphasizes certain features which are obscured, or some- times entirely masked, in the geographical distribution of other types, and it is therefore essential, if we would lay a firm foundation for zoogeographical generalizations, that the details of the distribution of all types should be carefully examined. Not only do the different classes of animals vary in the details of their relationships to the present land masses and their subdivisions, but great diversity is often found between families of the same order, and even between genera of the same family. Particularly is this true of nocturnal as contrasted with related diurnal types. As a group the onychophores have been strangely neglected by zoologists.

Abstract: Onychophorans, or velvet worms, are poorly known and rare animals. Here we report the discovery of a new species that is also the largest onychophoran found so far, a 22cm long female from the Caribbean coastal forest of Costa Rica. Specimens were examined with Scanning Electron Microscopy; Peripatus solorzanoi sp. nov., is diagnosed as follows: primary papillae convex and conical with rounded bases, with more than 18 scale ranks. Apical section large, spherical, with a basal diameter of at least 20 ranks. Apical piece with 6-7 scale ranks. Outer blade 1 principal tooth, 1 accessory tooth, 1 vestigial accessory tooth (formula: 1/1/1); inner blade 1 principal tooth, 1 accessory tooth, 1 rudimentary accessory tooth, 9 to 10 denticles (formula: 1/1/1/9-10). Accessory tooth blunt in both blades. Four pads in the fourth and fifth oncopods; 4th. pad arched. The previ- ously unknown mechanism by which onychophorans weave their adhesive is simple: muscular action produces a swinging movement of the adhesive-spelling organs; as a result, the streams cross in mid air, weaving the net.

    A REVIEW OF THE NEW WORLD ONYCHOPHORA WITH THE DESCRIPTION OF A NEW CAVERNICOWUS GENUS AND SPECIES FROM JAMAICA* BY STEWARTB. PECK Department of Biology, Carleton University Ottawa, Ontario KIS 5B6, Canada Few animals are as avidly sought and as rarely found by inverte- brate zoologists in the American tropics as are ony~ho~horans.Yet, attempting to determine any specimens which one is fortunate enough to find can be a frustrating experience because of the scat- tered and incomplete literature. In December 1972, while engaged in a survey of the invertebrate cave fauna of Jamaica, I discovered an eyeless and depigmented onychophoran. At that time, I knew that the only other known species olf cave-adapted (troglobitic) onychophoran, Peripatopsis alba Lawrence 1931, was from one cave in South Africa. To evaluate the status of the Jamaican troglolbitic species I undertook a review of the literature of New World Onychophora, and an examination of some 300 specimens in the collections of the Museum of Compara- tive Zoology (Harvard University) and the Institute of Jamaica. As a result, I have concluded that a summary of the literature on the systematics and distribution of New World onychophorans would be of interest, with the description of the new genus and species. General treatments of Onychophora morphology, anatomy, and biology are those of Cuenot (194g), Zacher (1933), Kaestner (1968), Barnes (1968) and the references cited in these and other invertebrate texts. The only systematic treatment of the Onychophora of the world is that of Bouvier (1905, 1907). Sedgwick (1908) reviewed the classification but did not formally add ,to it.

Mailing address: Biología Tropical. Universidad de Costa Rica. San José. Costa Rica (Rec. 4-VII-1994. Acep. 5-IX-1994) Abstract: A quantitative analysis of several onychophoran characteristics shows that in habitats with lower rain levels females reproduce at an older age, are more fecund and tend to have reproductive diapause where rain does not exceed a mean of 200 cm/year. These habitat characteristics are associated with the southern family Peripatopsidae. Sex ratio and parental investment per young are not correlated with general environmental conditions. A comparison of 72 species showed that larger species are often more variable in morphometry, but species with the longest females do not always have the longest males. Larger Peripatus acacioi females (Peripatidae: Brazil) produce more and heavier off spring. Intrapopulation morphology was studied in 12 peripatid species for which samples of between II and 798 individuals were available. In general, within populations the females are more variable than males in’ length and weight, but similarly variable in the number of legs. The number of legs has a low variability (1.73- 2.45%). length is intermediate (22.4-25.3%) and weight is very variable (49.41-75.17%). When sexes are compared within a population, females can have 14-8.9 % more leg pairs, and be 47-63 % heavier and 26 % longer than males.
