ELEUTHERODACTYLUS LOCUSTUS Schmidt 



Elcuthcrodactylus locustus Schmidt, Ann. New York Acad. Sci., vol. 28, p. 174, 

 1920. 



U.S.N.M. no. 78925 from El Yunque, Puerto Rico, June 27, 1929, 

 I assign with some hesitation to the above species, the type of which I 

 have not seen. The specimen in hand agrees with Schmidt's descrip- 

 tion except for the tympanum, which in the type is said to be " scarcely 

 distinct, one-fourth the diameter of the eye ", while in the present 

 specimen it is quite distinct and is over one-third the eye diameter. 

 My specimen measures 21 mm from snout to vent. It is dark brown, 

 with only faint traces of the dark interorbital band and some dark 

 rhombic markings on the labial regions. 



ELEUTHERODACTYLUS PORTORICENSIS Schmidt 



Eleuthcrodactylus portoriccnsis Schmidt, Amer. Mus. Novit., no. 279, p. 2, 1927. 



U.S.N.M. nos. 78923-4, an adult female with a number of hatching 

 eggs taken at El Yunque, Puerto Rico, June 27, 1929 : 



.... The strangest find was a frog — treetoad — with a mass of eggs in a 

 rolled-up pahn leaf, which she seemed to guard. The eggs were on the point 

 of hatching and began at once, on being exposed, to vibrate, and yielded their 

 young, which turned out to be not tadpoles but small jumping frogs. I gathered 

 a number of these, as well as the parent. 



This observation as to the egg mass being guarded by the female 

 has been made by two collectors — by Gundlach (Peters, Monatsb. 

 Akad. Wiss. Berlin, 1876(1877), p. 709) and by Bello y Espinosa 

 (Martens, Zool. Garten, vol. 12, p. 351, 1871) — and the dates on which 

 they found the developing eggs. May 24 and July 8, are borne out by 

 the date of the present find, June 27.
