OBSERV. The few specimens of this species, caught at the southern 

 extremity of the Peninsula of Bengal, being immature, it is but after 

 a long and protracted examination and comparison with the descrip- 

 tions of the writers upon this subject that we have come to their iden- 

 tification. The task has proved the more difficult as we lack an accurate 

 figure of the adult animal. The only one extant is given by Daudin, 

 under the name of B. bengalensis, which is identical with B. scaber, 

 figured by the same author, but so poorly as to render it of no avail 

 in a. critical point of view. 



In order to afford naturalists the means of identifying with accuracy 

 the species now before us, we have caused figures to be made, 

 although the specimens are immature. Should we have mistaken
