120 U.S. NATIONAL MUSEUM BULLETIN 288 



Until adequate material has been collected near Buenaventura, the 

 name pachydermus is provisionally retained. 



The original description (O. Schmidt, 1858, p. 257) is translated 

 as follows: 



[Diagnosis:] A Phirix with both anterior and posterior feet very robust; head 

 moderate; snout prominent; skin calloused, thick, color sulphur-yellow on whitish, 

 with blue lines on the back, on the femur, and also on the posterior femur. 



As we have already mentioned under generic characters, this animal has a 

 massive build in its flanks and limbs; in fact, the head, although of medium size, 

 shows this thickened characteristic. Its upper central part is horizontal and 

 deepened; the depth of the occiput is bordered by a pair of swollen borders, which 

 appear as the continuation of the equally swollen supraorbital borders. The nostrils 

 are almost as far from the rounded [dome-shaped], prominent snout tip as from 

 the inner eyelid. 



The forelimbs are unusually stout, the hands indeed as if stuffed, a rudiment 

 of the thumb [metacarpus] distinct and likewise a distinct although very flat 

 tubercle on the outer ball [palm] besides; first finger thick, short, and rigid, and 

 bending a little towards the second finger. On the tarsus of the hind foot are two 

 weak tubercles. Their web is so thick and, so to speak, leathery, that it gives 

 scarcely the impression of being a web. It is so stiff between the first three toes 

 that these cannot be laid side by side, and indeed the remaining toes do not 

 possess the usual mobility. The sole appears very broad and solid. The first, 

 second, third, and fifth toes are buried in the connecting web, the first and second 

 so that they appear only as a pair of blunt tubercles. The webbing forms a border 

 on the fourth toe from the level of the second articulation. 



The skin texture, resembling that of a pachyderm, is thick and marked with 

 weals. 



Color: The back shows, on a yellow ground, continuous irregular blue markings 

 which in the center enclose three light spots; a pair of continuations of these blue 

 lines are extended on the thigh. Another blackish blue mark, rather regular and 

 symmetrical, runs transversely over the posterior part of the back and on the 

 underside of the thigh. A distinct mention is merited of the blackish color of 

 the top of the first finger of the forelimb. The entire venter is yellow without 

 interruption. 



Size: Body, 53 mm.; forelimb, 40 mm.; hind limb, 75 mm. 



Habitat: Western New Granada, near Buenaventura, [Valle,] at an elevation 

 of 5,000 feet. Very rare.

Description. — MLS 143, an adult female from Paramo de las 

 Papas, Cauca, Colombia. Head as long as broad. Tongue two-fifths 

 as wide as mouth opening, oval, its posterior border free and unnotched; 

 snout short, broadly angulate when viewed from above, truncate in
