MEXICAN TAILLESS AMPHIBL^NS 165 



among the specimens of this species now deposited in the United 

 States National Museum. 



Giinther's Hyla euphorbiacea was based on five specimens, which 

 are clearly identical with H. eximia. The following notes were made 

 on these cotvpes: 



B.M. No. 1930. 4. 10. 2: Collected by Auguste Salle at Cordoba in 

 Vera Cruz and figured by Gtinther in 1858; head-and-body length, 

 30.2 mm.; the hind limb being carried forward along the body, the 

 tibio-tarsal joint reaches to posterior margin of eye; normal color 

 pattern. B.M. No. 57. 10. 28. 51: From the Cordilleras of Mexico 

 and purchased from fi. Parzudaki; head-and-body length, 33.8 mm.; 

 the hind limb being carried forward along the body, the tibio-tarsal 

 joint reaches to center of eye; normal color pattern. B.M. No. 

 58. 11. 22. 5: From the Cordilleras of Mexico and purchased from 

 £. Parzudaki; label states that it was found "dried up" in 1906. 

 B.M. Nos. 1858. 6. 15. 4-8: From Hugh Cuming's Mexican collection; 

 head-and-body length, respectively, 39.8 and 40.3 mm.; the hind Hmb 

 being carried forward along the body, the tibio-tarsal joint reaches to 

 posterior margin of eye in one, and almost to center of eye in the 

 other; a black can thai stripe edged above ^^'ith white; and a post- 

 ocular lateral dark stripe edged above with white, which tends to 

 disappear on posterior half of side of body. 



The cotypes (B.M. Nos. 1901. 12. 19. 76-82) of Hyla nana Giinther 

 (pTeoccupied = Hyla smithii Boulenger) are likewdse referred to this 

 species. Dr. E. R. Dunn carefully checked a series of specimens of 

 H. eximia with the cotypes of H. nana and concluded that this species 

 was not valid. Converseh', H. W. Parker, who had previously exam- 

 ined the cot^^pes, wrote that H. smithii seemed to differ from both 

 H. eximia and H. gracilipes. The seven cotj^pes of H. nana [ = smithii] 

 were collected by H. H. Smith at Cuernavaca in Morelos. My own 

 observations on one of these cotypes are as follows: Head-and-body 

 length, 25.8 mm.; transverse diameter of tympanum, 1.2 mm.; 

 transverse diameter of eye, 2.5 mm.; anterior edge of eye to nostril, 

 2.6 mm.; the hind limb being carried forward along the body, the 

 tibio-tarsal joint reaches to anterior margin of eye; no tarsal fold; an 

 elongate inner, but no outer metatarsal tubercle; vomerine teeth quite 

 small and in two clusters between the choanae; side of head from tip 

 of snout to eye and from margin of upper lip to canthus rostralis 

 dark brownish black, but edged above with a narrow light line; a 

 black streak between eye and tympanum; behind tympanum this 

 dark lateral band tapers posteriorly to a narrow ribbon and disappears 

 on fianks; upperparts j-ellowish or olive-green; abdomen and under 

 surface of thighs yellowish; skin on abdomen and under surface of 

 thighs granular. The development of the vomerine teeth and the 

 size of these cot3"pes indicate that none of them are fully adult. The 

 largest individual lacks a tarsal fold and has a dark loreal region.
