FROGS OF COLOMBIA — COCHRAN AND GOIN 253 



Dimensions. — Head and body, 39.6 mm.; head length, 15 mm.; head 

 width, 15 mm.; femur, 18.2 mm.; tibia, 20.4 mm.; heel-to-toe, 30.4 

 mm.; hand, 12.8 mm. 



Color in alcohol. — A rather dark gray frog without much pattern. 

 Along the sides, where the dark gray of the dorsum merges gradually 

 with the cadaverish gray of the venter, inconspicuous small black 

 specks may be seen; a few similar specks are present on the lateral 

 margins of the shanks, feet, and hands. 



Remarks. — Dr. Dunn reported on the pattern variation as seen in 

 labialis, and we quote his discussion here (Dunn, 1957, p. 11): 



The most frequent coloration is a rather uniform bright light green above, 

 paler below and with blue in the concealed surfaces and, in large individuals, on 

 the belly also. A black line runs from the nostrils back over the tympanum to 

 widen and fade out on the body. This was the color of the types of labialis and 

 of vilsoniana. The black line may be lacking in some bright green individuals 

 (types of gularis). There is some ability for color change in individuals in life (in 

 tone, not in pattern), and most of the uniform specimens darken in preservation, 

 but there are also very dark olive green individuals (almost black) and the black 

 line does not show up in these either (types of creolica). 



Green individuals may be irregularly spotted with black on the whole dorsal 

 surface (type of servalina). Very frequently the green is not uniform, diffuse 

 black pigment producing darker sides and a darker dorsum, the two separated by 

 a light dorsolateral band, and the dorsum divided by a lighter and vaguer mid- 

 dorsal light line wider and more prominent posteriorly. These also may have the 

 black "servalina'" spotting. 



An occasional frog may not be any shade of green at all but a golden brown, 

 either uniform or with the lighter dorsolateral band. A combination of the striping, 

 the "servalina" spotting, with green and golden brown each forming irregular 

 parts of the background produces a very gaudy frog indeed. 



I have kept these different color forms alive for days and the individuals main- 

 tained their colors constantly, except for a little darkening or lightening of the 

 general tone. 



After having collected and studied the form in life in Bogota and 

 its environs, we can add nothing pertinent to the above discussion. 



We have seen the two specimens (MZUM 48283-4) that formed 

 the basis of Ruthven's (1922, p. 55) report of the species from Santa 

 Marta. While the two individuals do seem in general characters to be 

 perhaps related to the labialis group, they cannot, in our opinion, be 

 referred to either H. I. labialis or H. I. platydactyla. They do have a 

 patagium, but it is impossible, in their faded condition, to tell if it 

 was pigmented in life. One of the specimens seems to be immature; 

 the other is an adult female that measures 24.5 millimeters in head- 

 body length, appreciably smaller than adult females of H. I. labialis 

 or H. I. platydactyla. Likewise, the vomerine teeth series seem to be 

 shorter than in typical H. I. labialis. 



Two specimens in the British Museum (BM 1902.5.15.23-24) are 

 here referred to this form. One of the two is now pale gray with black,
