FROGS OF COLOMBIA — COCHRAN AND GOIN 399 



the back and on the dorsal surfaces of the limbs, and is palest gray on 

 the chin, chest, and belly. 



Remarks. — Another example (CNHM 54760, from Santa Cecilia, 

 Pueblo Rico, Caldas, at 800 meters on the Pacific side) has the dorsal 

 surface covered with round dark spots becoming smaller on the 

 limbs. The outer toes and fingers of this frog are slightly pointed, 

 a condition not existing in the described specimen (MLS 196); other- 

 wise, the two are quite similar. A much larger series is needed before 

 an estimate of variation can be given. 



As has been noted by B. Lutz and by Charles Walker (in lit.), 

 the specimens in the type series of Pseudohyla nigrogrisea, which 

 consists of one adult and five juveniles, are not Hyla but are damaged 

 Eleutherodactyl us. 



Specimens Examined 



COLOMBIA 



Caldas: Pueblo Rico, Santa Cecilia, 800 m., CNHM 54760. 

 Norte de Santander: La Selva, MLS 196. 



Eleutherodactylus surdus cabrerai, new subspecies 



Plate 52a-c 



Holotype. — AMNH 14009, an adult female from Andes, Antioquia, 

 Colombia, collected by Hno. Niceforo Maria. 



Diagnosis. — Head without bony ridges; vomerine teeth in two 

 very small, transverse, widely separated series behind choanae; 

 upper jaw projecting slightly beyond lower; diameter of eye a little 

 less than its distance from tip of snout; tympanum concealed; first 

 finger much shorter than second; toes faintly webbed, all with pro- 

 nounced lateral ridges; adpressed heel reaching a point between eye 

 and nostril. 



Description oj holotype. — No bony ridges on top of head. Vomerine 

 teeth in two very small, widely separated, transverse series behind 

 the choanae; frontoparietal area slightly depressed; tongue two- 

 thirds as wide as mouth opening, broadly cordiform, its posterior 

 border free and deeply notched; snout moderate in length, rounded 

 when viewed from above and in profile, the upper jaw extending 

 slightly beyond the lower. Nostrils dorsolateral, slightly projecting, 

 their distance from end of snout one-half their distance from eye. 

 Can thus rostralis rounded but distinct; loreal region deeply concave, 

 sloping outwards to the upper lip. Eye large, prominent, its diameter 

 a little less than its distance from tip of snout; interorbital diameter 

 a trifle greater than that of upper eyelid, distinctly greater than 

 interval between nostrils. Tympanum concealed, but with a depressed 

 area where it would have normally occurred. Fingers fairly long,
