 last ; the fifth tooth has a canine-like form, a little more prominent 

 than the preceding, and curved forward ; the sixth small, conical, 

 vertical in position, and widely separated from the fifth.

3. On the Species of Craspedocephalus which occur in 

 THE Province of Bahia, Brazil. By Dr. Otho Wu- 



CHERER, CORR. MeMB. 



In a former paper, containing the first portion of a list of the 

 Ophidians which I had been able to collect in this province, I abs- 

 tained from certain remarks on some species of the above genus 

 until I should have collected more ample materials to corroborate 

 them. 



In the first place, I was struck by the fact that all the specimens 

 of " Jararaca " which had up to that time come to my notice were 

 very similar and belonged to one species, Craspedocephalus atrox. 

 Having collected more than thirty specimens, I proceeded to examine 

 them more closely for comparison. Dr. Gray, in the ' Catalogue of 

 Viperine Snakes in the Brit. Mus.' 1849, comments on the difficulty 

 of separating the species of this genus. His diagnoses do not agree 

 exactly with those of Schlegel in his ' Essai,' nor with those of 

 Dume'ril and Bibron in their ' Erpe'tologie Generale,' I may therefore 

 be excused if I oflFer the following remarks on my specimens. In 

 my former paper I stated that I had neither seen Craspedocephalus 

 lanceolatus nor C. brasiliensis. At the present time I have examined 

 very nearly forty specimens of " Jararaca," all of which, except three, 

 agree sufficiently in every character, and are, according to the de- 

 scriptions of herpetologists, referable to C. atrox. These three spe- 

 cimens show certain slight differences which justify a doubt of their 

 specific identity with the others. 



Dr. Gray mentions C. atrox as having seven upper labial shields. 

 Schlegel, in his ' Essai,' i. p. 189, and again ii. p, 535, describes this 

 species as having eight labial shields ; still this may perhaps be con- 

 sidered a mistake, for in his plate 19 of the above work C. atrox is 

 represented as having only seven upper labial shields. Dumeril and
