FROGS OF COLOMBIA — COCHRAN AND GOIN 177 



it merges with the dark brown ventral and lateral color; another pair 

 of fine lines originate on each upper eyelid, pass medially and poste- 

 riorly to the middle of the head where they fuse, and continue poste- 

 riorly along the midline of the back as a broadening line that posteriorly 

 broadens to completely encompass the opening of the pouch, after 

 which it abruptly terminates. There are a few spots on each side of the 

 middle of the back. There is a fine dark line along the entire margin of 

 the upper lip. A few dark stripes cross, or nearly cross, the top of the 

 thigh; otherwise the tops of the limbs are cream with scattered dark 

 spots; there is a band of brown across each wrist. The entire venter, 

 underside of the limbs, and the sides of the body are a rich chocolate 

 brown. 



Color in life. — "Bright yellow with reddish brown and white marks," 

 according to original field notes shown to us by Hno. Niceforo Maria. 



Note on life history. — Two gray-green (in life) young, about 20 

 millimeters in head-body length, were "born after capture." They show 

 the same pattern as the parent. 



Remarks. — Although Dunn (1944b, p. 404) described this species as 

 having the derm of the head fused with the skull, the head is really 

 quite free. We can offer no suggestions as to the relationship of helenae. 



The specimens in the series MLS 268 (the type and two juveniles) 

 were the only ones examined. 



Gastrotheca aureomaculata, new species 



Figures 14-16 



Holotype. — CNHM 69701, an adult male, collected in Huila, Colom- 

 bia, at San Antonio, a small village about 25 kilometers west of 

 San Agustin, at 2,300 meters. 



Paratype. — CJG 2307, collected at Moscopan, Cauca, Colombia, 

 by Marte Latham. 



Diagnosis. — -A Gastrotheca without the cranial derm co-ossified with 

 the skull, without superciliary processes, without dermal appendages 

 on the heels, and with the intersquamosal shelf incomplete posteriorly 

 so that it does not form a complete, transverse, straight margin at the 

 back of the head. In preservative it is black with numerous small spots 

 of yellowish white, both above and below. In life the ground color is 

 inky blue but greenish gold spots are so thickly spaced that the frog 

 from a little distance appears bright green. 



From the other species of Gastrotheca now known from Colombia, 

 this new species can be differentiated from bufona and cornutum by 

 the absence of superciliary processes; from nicefori and medemi by 

 having the cranial derm free from the skull; and from helenae, mertensi, 

 and monticola argenteovirens by having the dorsum and venter thickly 

 covered with light spots.
