L:ir;{i.'.st of ill! llu' Ni)rt!i .ViiiLMiitiiii spocies. IJody very Ixilky uiul 

 clumsy; It'frs tlii(!k \\\v\ slioii. .Iiiws lu^irly, if not qiiito, us wido as 

 {\w U'ligtli of cdonl of iii»iM'r j;i\v anil wider tiiaii tlio loiij^itiidiiial 

 axis of head; inii/-zlo s iWtniiiiMto ; sides ol»li(|ue. Nostrils ohliciuo, a 

 littlo below tlio cd;;e of tli<» cantliiis nostralis, half Wiiy between tho 

 ti|)ot snout and anterior caiitliiis of eye. Tyinpaniiin lar;4(^, sli^^litly 

 oviil, lonj^er diameter somewhat ol)li(|ue, eifual to the diameter of tho 

 eye; ;;raniilated and sli;;htly raised for the central two-thirds; smooth 

 exteriorly. Internal nares ellipticjal, transverse, wider apart than are 

 tlKM'xternal ; tiieircenteis opi)i>si!e a point about one-third from theoyo 

 to the outer nosti'il ; a siiallow ;;roove, extetidin,i,' to tho rami of tho jaw. 

 Vomerine teeth in f wo patches, with four or tiv(^ teeth in each i)at('h ; tho 

 liases of these anteriorly (»it])osite tluMU'nters of tiie inner nostrils, and 

 sei)arated from eaiih otiier by the s;ime interval as from the nare.s. 

 Hiistaehian tnbt's l.irj;(', nearly opposite tiie ocnters of lympanuin. 

 Ton;;iu^ elonj:ated, broadest at the stem. 



A fold of skin extends from fiie posterior ('anthus of the eye above 

 tlio tympanum, and<Mirvinj; round it proceeds directly downward to be- 

 hind the posterior extremity of the lower jaw ; it then passes ar()und tho 

 insertion of the fore-arm (distant about half the <liameter orbit) and is 

 lost on the breast. This fold is only consj)icuous to the lower end of 

 tlie tympanum ; it is aceompanit'd all the way hy a groove on its lower 

 e(lj,a', both being scarcely traceabhi beyond the point above mentioned, 

 excei)t in very wiiU preserved siu'cimens. Theie are no other folds of 

 skin; esi)ecially noneon the si(b> (»f (he back. The skin above is slightly 

 shagreeneil by moderate asperities, whicih increase posteri(nly. I>eneath 

 smooth. Tlu^ posterior laces of tho buttocks rugose-granulated. 



Tho tliird finger (the second from outsi<le) is h)ngest, then fourth, 

 first, and second. AH are without any membranes or web. Tho tibia 

 is not quite half tho length of body. The fourth t(»e is longest; tho 

 tliird ratlier longer than the liflh ; then second and lirst. All are cloft 

 (except as to membrane) nearly to the base of tho metatarsals, deepest 

 along the first and lifth. The web tills up the entire interval, extend- 

 ing from tip to tip of the toes; the outlines lu'arly straight when out- 

 stretched. 



The color above is olivaceous-brown, with darker blotches about lialf 

 tho diameter of the oyo distril)uted pretty uniformly; o(;casionally 

 in conta(!t ami conlluent; the outlines obsolete or n(»t clearly marked. 

 Tho buttocks ai'e similarly marked, witli tlie 1)lotches nearly black. Tho 

 jonits of tho fore leg have each one or two bars or blotches; those are 

 ntoro distinctly transveise on the hind legs, where there are three or 

 four on each joint. Membiane of himl foot finely mottled. The lower 

 l)arls, including groin, are silvery white, with similar coai*se blotches 

 or mottlingsof obs(!olescent brown, though not ((uito so much crowded 

 as above; this pattern pervades the whole inferior and interior faces of 

 body and limbs, leaving no portion unmarked. Tho tympanum is rather 

 darkest in the center.
