Tlu' species is stout and lieav.v in ItniM; llie lieail \eiy liroad nnil 

 niiieli (lepresscd. Tlie sliin is },nannlated I).v citntraction of the alcolml. 

 but in respd't lit jilaiids, pits, etc., appears niiicli like otiiei species. 

 Tliere is, lidwever, a de(!ide(l realiin' in ccitain particles wiiicli eiinvd 

 tlie paiotoid re;:ion, and are seen also on tlie top of tin- head alonj^ the 

 inner inarjiin of the orbit, and perliaps below the ev«'. I liaxc not 

 noticed this character in aiiv otiiei' species east of the itocky Mourdains. 

 The head is bioad, ovate, ratiier ]>oiiited anteiiorl.v. The inner and 

 outer nostrils are nearly the same distance apart. The tonjiiie is broader 

 than loiifj', more than half the width of tlie head, lillin;; the intersi)ace 

 of the same anteriorly. 



Tl»' teetli are in Ibnr very distinct patches, with d»'cided intervals. 

 Thoy form one tr.insveise series, nearly straij^ht (teiitraily (where they 

 are in a line with the posterior Ixtrder of the internal iiares), but ciirvin;; 

 slij,ditly backwards lateially. The two central patches aie wider than 

 the lateral, which vaiy a little in Icnutli and are separaled by iiii inlei- 

 val half the diameter of the inner nates. Their fjistance from the exte- 

 rior patches is al>oiit twice as j^reat, the center of the interval falliiii; 

 about ()pp(»site to the inner bolder of iiiiiei' iiares. The outer patches ex- 

 tend about half a diameter iteyond the outer border of inner iiares. 



The remaining;' external cliaractti'is of the speciincn are not dill'eieiit 

 from those of .1. lifiriinnit. 



The colors of the specimen are much obscured by bad preservation. 

 It appears to have b(>eii of a iiiiiforii) dark blackisli or bluish brow n, with 

 a sin;;!e sei'ics of lar^c transversely elliptical blotclics of yellow from 

 head to tip of tail, half on body and half on tail; the foremost one 

 rounded and ]>lac(Ml behind the eyes. Those of opposite sides nearly 

 meet on the back, and aic c(Uilliient on the iipi>er cdyv of tlu' tail. 



This is the only species I have .seen of the ■;ioiip in which a strictly 

 transverse series of palatine tee.th behind the eye is divided into Ibnr 

 {ironjis. 

 The only known specimen is the Ibllowinji :
