 spines 3, rather strong, the middle one largest; first dorsal spine slightly 

 longer than second, which is nearly or quite free from the soft rays; gill 

 rakers short and thick, about 8 developed. Color brownish, irregularly

*We have examined numerous specimens of this species, inclndinp; the original types of nigri- 

 pinnis, mamdalm, and deroidliis. There is no doubt whatever of the identity of these three. 

 li. viacidatus. Gill, is said to have 3 dorsal spines, but this is an error, the first (broken) soft 

 ray on the type having been counted as a spine. SVe have compared I{. nigripinnis witli R. his- 

 trispinns, and find the two apparently different, although very nearly related. In nigripinnis the 

 body is less deep, and there are 3 opercular spines, while the Atlantic species has usually but 2.
