22 U.S. NATIONAL MUSEUM BULLETIN 278 



collected in the Mediterranean Sea, off Havana, Key West, and 

 Beaufort, North Carolina. 



Ruffo (1938) cites this species as occurring off Brazil and Guiana; 

 however, in personal correspondence he has advised me that he was 

 referring to C. acutifrons s. lato and not specifically to C. andreae. 



Mayer's specimens from his localities 3-7 were obtained from the 

 Copenhagen Museum. I have selected a lectotype and an aUolecto- 

 type from locahty 4, 38°10' N., 64°20' W. 



Caprella hermudia Kunkel, 1910 



Caprella bermudia Kunkel, 1910, pp. 108-110, fig. 42. 



Remarks. — Kunkel's description of this species is inadequate to 

 separate it from C. equilihra. It has not been included under C. equilibra 

 because I have not been able to examine the type material. Inquiries 

 at most of the larger museums in Europe and North America have 

 not revealed their location.
