The total tylus cundalli, gossei, pantoni are native fauna of is both far its in- anuran Jamaica discussed, as as ternal (within Jamaica) and external (other Antillean islands) re- lationships are concerned, and a zoogeographic picture of differenti- ation from two major evolutionary centers in Jamaica is presented in reference to the frogs of that island. The frogs of Jamaica were last reviewed by Lynn (1940). At that Lynn 17 time, recognized species of anurans on the island of Ja- maica, of which three (Bufo marinus, Eleutherodactylus “martini- censis", E. “ricordi”) were consideredintroduced species. Taxonomic and distributional LYNN'S work few: these papers subsequent to are include LYNN & DENT (1942, 1943), LYNN (1954), GOIN & COOPER and GOIN in of three GOIN (1950), (1953). However, a series papers, (1950, 1954, 1960) discussed the genetics and evolution of several of insofar these of Jamaican species Eleutherodactylus; as aspects their biology are concerned, the Jamaican membersof the genus are consequently better known than are those of other Antilleanislands. Our interest in Jamaican frogs stems primarily from four col- lections made in Jamaica in the past decade: Schwartz (with David C. Leber and Ronald F. Klinikowski) collected on the and A second collection island between 9 June 7 August 1961. was made by Richard Thomas between 29 June and 10 September 1967. Schwartz, with James A. Rodgers, Jr., collected very briefly in Jamaica in 1969. Finally, we (in the company of Dale E. Becker and Michael T. Felix) collected in Jamaica between 1 and 25 August 1970. The result of these efforts is slightly over 2,000 freshly collected and carefully documentedand preserved specimens, all of which add of the her- materially to our knowledge Jamaican The of the is summarize petofauna. purpose present paper to new data and to bring the knowledge of Jamaican frogs closer to that of the frogs of other Greater Antillean islands. 52 the We acknowledge assistance offered the senior author on 1961 by C. Bernard Lewis of the Institute of and the of Jamaica, cooperation our companions, Messrs. Becker, Felix, Klinikowski, Leber, and Rodgers, in the field. We are especially Richard Thomas for grateful to allowing us to report on his Jamaican material. All specimens are in the Albert Schwartz Field Series (ASFS).

We are grateful to Ronald I. Crombie of the United States National Zoological Park for pointing out the priority of crucialis Harlan over lichenata Gosse for the giant Jamaican hylid. We have had no field experience with E. alticola, a species known only from high elevations in the Blue Mountains of extreme eastern marinus Jamaica, and, although we heard Bufo vocalizing and saw individuals on the roads collected many at night, we no specimens and thus have no new data to p~esent on this bufonid. But we do information all other have new on Jamaican anurans. These new data information distribution altitudinal include on variation, (both and and geographic), ecology, vocalization; especially pertinent are data in coloration and pattern in living specimens and measure- of both which in have ments sexes, most cases never been reported.

As is in far as possible a linear series, we have attempted to each arrange the species within genus in what seems to us a reason- able Our ideas based phylogenetic sequence. are primarily upon the work of Dunn on the hylids and Goin on the leptodactylids the but have (especially gossei group), we departed to some slight extent from Goin's suggested relationships. Our interpretations are noted in the text and are detailed in the discussion section of the present paper. 54 Our distribution the known of the maps attempt to present rangs various species and subspecies of Jamaican frogs. Hyla brunnea Gosse Hyla brunnea is the second largest of the Jamaican hylids, and the is distributed the both species widely throughout island, geo- graphically and altitudinally (Fig. 48). Our twenty-five largest males (all with nuptial pads) have the following measurements: snout-vent length 42.1-50.6 (45.6); head length 16.0-18.7 (17.4); head width 16.0-19.2 2.9-3.8 5.9-7.8 (17.6); tympanum (3.4); eye (6.7); naris to eye 5.2-6.8 (6.0); femur 17.6-22.8 (19.7); tibia 20.0- 25.8 (22.3); fourth toe from inner metatarsal tubercle 15.1-20.7 (17.9). The largest 25 females measure: snout-vent length 60.4-75.8 (65.7); head length 21.7-27.0 (23.7); head width 22.4-29.2 (24.8); tympanum 3.8-5.5 (4.5); eye 5.9-7.8 (6.7); naris to eye 7.3-10.5 (8.4); femur 26.2-34.3 (28.9); tibia 29.6-38.6 (32.3); fourth toe from inner metatarsal tubercle 24.1-32.8 Lynn (26.5). (1940: 20) gave 72.0 mm as the measurementof the largest frog (presumably female) which he had available, and our largest female slightly exceeds his in snout-vent length. Lynn (1940: 20 and pi. I) discussed and figured the variationin dorsal color and pattern in H. brunnea. The species is exceptionally variably in dorsal pattern, with some specimens unicolor and whereas others marked with patternless or virtually so, are large and dark The colors irregular blotches or mottling. primary involved in the dorsal pattern are browns, with the ground color usually a medium brown and the pattern, if present, some darker shade, in almost black. Usual dorsal colors some cases are in the vicinity of PI.
