1859. GiRAUD, CuAKLES — Continued. 



that purposi' were prepared at the Smithsonian Institution under their supervision and care, 

 inehidin;; those aceonipanyiiii; the reports ol' Drs. Cooper and Hallowell, as shown by the 

 uniiiue serial numeration. In the mean time the characteristics of tlie new genera and sjjecies 

 appeared in tlie I'roceedinijs of the Academy of Natural Sciences of Philadelphia. (See above, 

 Nos. 34, 35, 36, 37, 39, and 03.) Professor Baird being personally in charge of the reports upon 

 "mammals'' and "birds," and Dr. Girard of the report upon "lishes," there was not sufficient 

 time to do justice to the report upon "reptiles." Dr. Girard being called abroad, the entire 

 task fell upon Professor Baird, who prepared all the data upon the subject, describing such 

 uew species as had not been characterized before. It is much to be regretted that plates xxiv 

 to xxxvi appeared with a merely nominal explanation, when a comparative discussion of all 

 the genera and species figured was contemplated by both of the herpetologists named. 



The following list enumerates the species which have beeu studied by Dr. Girard, under 

 whose direction the plates were proiiared.
