genus recognized herein are closely related. But they differ in the number of gill rakers 

 on the lower limb of the first arch, viridis having 27—30 while lamprotaenia has only 

 19—24 (usually 20 or 21). That there is a difference between the species in the inser- 

 tion of the pelvic fin, as stated by Rivas (108: 3), I am unable to substantiate, as it 

 seems to be obliterated by the variations among specimens. However, according to four 

 viridis and seven lamprotaenia that remain almost fully covered with scales, in the former 

 39—41 oblique rows of scales cross the lateral band between the margin of the opercle 

 and the base of the caudal, whereas in the latter only 33—37 series cross this band. 

 The specimens of viridis at hand have much more prominent mucous canals and pores 

 about the head and on the anterior part of the body, but they may not be specifically 

 significant. 



It so happens, then, that even though T. H. Bean placed this species in the 

 wrong genus and family {Stolephorus^ family Engraulidae), his species still remains 

 valid (9: 22). 



Commercial Importance. This species is not known to be of direct commercial 

 importance. It has been reported as exceedingly common in Bermuda (9: 123; JJ: 37), 

 therefore it must be valuable as a forage fish. 



Range. Known only from Bermuda and vicinity. It congregates in schools like 

 lamprotaenia but ventures some distance offshore, as shown by the Grampus catch noted 

 above.
