AMPHIBIA NS AND REPTILES OF BEXAR COUNTY 15 



20. Hyla versicolor chrysoscelis Cope. Western Tree Frog 



Hyla femoralis chrysoscelis Cope, Bull. U. S. Nat. Mus., 



No. 17, 1880, p. 29. 

 Five specimens from Helotes were in the Marnock col- 

 lection. These specimens are perfectly smooth above and resem- 

 ble in every particular typical specimens of chrysoscelis from 

 the type locality. This is the common Hyla of middle and 

 northern Texas. 



21. Eleutherodactylus latrans (Cope) 



Robber Frog: Barking Frog 

 Lithodytes latrans Cope, Bull. U. S. Nat. Mus., No. 17 



1880, p. 25. 

 This interesting amphibian was described from specimens 

 collected at Helotes by Marnock. Judging from the number of 

 fine examples in the Marnock collection, it is not at all un- 

 common. 



22. Syrrhopiis marnockii Cope Marnock's Frog 



Syrrhopus marnockii Cope, Am. Nat., Vol. 12, 1878, p. 253 

 The type locality for this species is given as "near San 

 Antonio, Texas" but the types were really from the vicinity of 

 the Marnock homestead on Helotes Creek. Like Eleutherodacty- 

 lus latrans, this frog inhabits limestone bluffs. Although dis- 

 covered more than forty years ago, it has not been found in any 

 other locality. 



23. Rana catesbeiana Shaw Bullfrog 



Rana catesbeiana Shaw, Gen. Zool., Vol. 3, Pt I, 1802 



p. 106, fig. 108. 

 The bullfrog is a common species in Bexar County. 



24. Rana pipiens Schreber Leopard Frog 



Rana pipiens Schreber, Naturforscher, Vol. 18, 1782, 



p. 185, pi. 4. 

 Generally distributed throughout the county. Very 

 abundant in the San Antonio and Salado rivers and in Helotes 

 Creek and other small streams. 



25. Gastrophryne texensis (Girard) Texas Toothless Frog 



Engystoma texense Girard, Proc. Acad. Nat. Sci. Phila., 



1859, p. 169. 

 Cope did not recognize this tiny species and recorded the 

 toothless frog of Bexar County under the name of Engystoma 

 carolinense, which is entirely distinct from Girard 's species. 

 Texensis is distributed in suitable localities all over Bexar Coun- 

 ty. I have eight from Helotes, several from the St. Louis College 

 grounds and a number that I personally obtained while on 

 clamming trips along the San Antonio and Salado rivers. Cope 

 mentions carolinense ( ?) from the city of San Antonio.
