502 NEW SPECIES OF CALLIONYMUS. 



A mutilated specimen of tlie same species from the same region was re- 

 ceived iu 1886, and is mentioned in these Proceedings for 188C, page 

 476. 



This species is very different from C. pauciradiatus Gill, the only 

 species of CaUionymns thus far known from our coasts; the much greater 

 number of dorsal and anal rays, as well as the development of the pre- 

 opercular spine being good distinctive characters. 



I have named this species for Trof. Spencer F. Baird, to whom I 

 have been indebted for aids of manj' kinds iu connection with my studies 

 of American Ushes.
