Cope] l'^" [July 16, 



from the Rio Grande do Snl, Brazil. It is nearest the B. nieuwiedii, 

 Spix, but may be distinguished by the extraordinary character of the 

 silky fringes in the mouth as well as by the entirely different coloration. 

 In the latter respect it is rather more like B. diporus. 



Cnemidophortjs grandeksis, Cope, sp. nov. 



Char. Ten series of abdominal plates ; brachium plated ; two fronto- 

 parietals. Green with 2-3 white longitudinal lines on each side, a row 

 of brown spots between the two superior and above the more dorsal of the 

 latter. 



Description. The nostril is anterior to the naso-frenal suture. Infra- 

 labials four, separated from labials behind by one series flat scales (not 

 granules), mesoptychium entire, with 3-4 rows plates, some small ones 

 on the margin, except at middle. Supranasals in contact ; also the pre- 

 frontals. Frontal single, much angulate in front. Supraorbitals four, 

 not separated from frontals and frontoparetals by granules. Two pairs 

 wedge shaped parietals, interparietal narallelogrammic as large as one 

 pair. Scutellation minu.te, caudal scales strongly keeled. Brachials and 

 antibrachials continuous, latter in two rows only ; former continuous 

 with postbrachials, the two forming together five rows, all smooth. Nine 

 femoral pores. Anals continuous with abdominals, composed of one 

 large median plate, margined laterally and behind by six plates, the two 

 posterior marginals. 



Coloration. — The inferior lateral pale line is interrupted aud not well 

 marked ; sides pale green, between and above the superior lateral lines, 

 brown ; median dorsal line bright green. Nineteen brovvn spots between 

 nape and rump above upper line, those below rather fewer. Femur with 

 two pale streaks behind, tibia and fore-arm spotted in front. Belly and 

 throat uniform yellow. 



Habitat. The Rio Grande, Brazil, brought by Capt. George Harrington, 

 and presented to the Essex Institute, Salem, Mass., (No. 388,) Mi\seum 

 Academy Natural Sciences, Philadelphia. 



This species only resembles the C. murinus, D. B., and the C. hetero- 

 lepis, Tschudi in the increased number of its abdominal shields. In C. 

 murinus the brachium is altogether granular, while the C. heterolepis 

 differs in having but one frontoparietal plate, and only two parietals, 

 with frontoparietal smaller than either. It is from Peru. 



On account of the united frontoparietal shields I refer C. hypery- 

 thrus. Cope as type, and C. heterolepis, Tschudi, as second species 

 of a genus different from the present, under the name of Verticaria.
