H'SPsiBOAS HYPSELOPS, Cope, sp. nov. 



Of the group of H. crepitans Wied. The fingers are not webbed beyond 

 the basis of the proximal phalanges, except perhaps on the external one. 

 When the arm is extended, they reach a trifle beyond the groin. The 

 hind limb extended brings the heel a little beyond the muzzle. The 

 general form is slender ; the head broad and flat. The canthus rostralis 

 is distinct, but very concave, and the rostrals prominent on a narrow 

 truncate muzzle. The outline of the head is rather acuminate to the apex, 

 intermediate in form between H. crepitans and H. boans. The eyes are 

 very large and prominent, entering only 1.5 times in the rather elongate 

 muzzle. The tympanum is small, one-third the orbit in diameter and one- 

 half the interorbital width. Dermal free, margins none ; a slightly promi- 

 nent fold on the elbow and spur on the heel, only a prominence on the 

 other. Skin above smooth. Digital dilatations hardly .50 diameter of 

 tympanic membrane. 



Color, above bright chestnut brown, below i3ale violet ; no marks on the 

 head or back. Upper arm of the same color, as is a band on superior face 

 femur. Front and back of femur, sides .66 of distance to axilla, andintero- 

 anterior face of tarsus and metatarsus, with vertical black bands. They 

 are very distinct and wider on the front than the back of the femur ; the 

 latter connect faintly above. Three or four faint crossbars on tibia above. 

 Two black sijots on back of brachium, and one or two on front of ante- 

 brachium. 



Vomerine tooth series arched as in other species, tongue broad. Ostia 

 pharyngea very small, one-fourth choanse. 



Length of head and body, Om. 056 ; of hind limb, .091m ; of foot .OSSm; 

 of tarsus .02 ; width of jaws below tympanum .02 ; length from same 

 point (axial) .016. 



The acuminate muzzle, larger eye, and anterior femoral bars, distin- 

 guish this from the H. crepitans. The same characters separate it from 

 H. indris, with the additional ones of smaller tympanum and larger limbs.

*The name of the allied genus CincUdium, Journ. Ac. N. Scl. 1867, 200, having been used before 

 for a valid genus of plants, I propose to change it to Cincloscopus.
