208 AMERICAN JOURNAL 



This monograph, which is very carefully worked up by the 

 principal authority on the subject, contains descriptions of two 

 hundred and twenty-three species, of which a large number are 

 herein first described by Mr. Marrat. 



Perhaps some of these new species will not stand, as the cha- 

 racters are very confused and evanescent in this genus, requir- 

 ing many specimens to ascertain the variations in some of the 

 species.
