The tail is a little slioitrr than the hoilv ami licati (iiicasiiriii^- IV<»m 

 postciior extrcinit.vol' vent). It is oval in cross section, widest, helow, 

 tlion^jli without any riil^je or crest. It is little liiylier tliiiii Itroad at the 

 anns, hut heconies more and more compressed to the tip, the upper and 

 under outlines remiiiniii;^ nearly parallel for a consideraldc^ distance. 

 The anal .slit is proloujjed into a }:roove, which extends heiieath the, tail 

 (o its very tip. 



The limhs are lari^ely developed and the toes ver.v lonp-, Thedifjils 

 arc cylindiical, depressed, without any lateral or itasal weh. The third 

 linj^cr is longest, then the second, fourth, and tirst. It is one third the 

 Icn^jth of aim from elliow. The fourth toe is louj^est ; then flu^ third 

 (l)iit little sliorlci), second, tilth, and first ; it is contained altont two and 

 one-half times in (he length of leu from knee. The expanse of the out- 

 stretched toes is very nearly etpial to thedistance from snout tothe uroin. 

 The lenj;lh of the lindts vaijes a little ; when extended on the sides they 

 may scarcely meet or considerably overlap. 



The toufi'ue is thick and Ihvshy. much as in .1. jtuurtutiim. 



The teeth are in four patches; the two central in a nearly stiai^iht 

 line, or foiniiiij; in smallei- individuals a very obtu.se /\ , the aniile ante- 

 rior but not pn.ssiii}; the posterior l)orderof the interim I imr«'s. Thesi<les 

 of th(^ V are perhaps slijjhtly c(»nca\(' anteriorly. This patch or line 

 extends to the innei' nares. and is there continuous with the lateral 

 patches, which are slioit, nearly straij^ht, about one t'ouith tlu' cen- 

 tral patch, and form the iJOfjterior border of tlu- inner nares. These 

 are larye. far back, and widely separated. 



In .il(M)h(»l, aftei' lon^' immersion, the specimen is nearly uniform fi^iht 

 liver brown, paler l)eneal4i, without any spots.
