mouth very large; jaws squarely truncated behind; teeth uniserial, those of the 

 upper jaws moderate, of lower jaws enlarged and largest at sides; dorsal and anal 

 almost symmetrical, dorsal commences in front of eye on snout, scarcely deflected on 

 blind side; caudal slightly pedunculate and convex; pectorals subequal and with a 

 subtruucate free margin; ventral nearly equal, the left on the preanal ridge, the 

 right lateral, both with the inner rays connected by membrane to the body; inter- 

 brauohial membrane imperforate ; gill-rakers tubercular and surmounted by blunt 

 <lenticles. 



Type C. fiinbriata The scales on the eyed side are regularly cycloid with the 

 nucleus some distance from the posterior margin and with numerous radiating 

 striic. The gill rakers are quite characteristic. 



The si)ecies about to be described is distinguislied from the type of 

 the genus by its shorter head, smaller and closely adhering scales, 

 larger teeth, the little- produced anterior dorsal rays, and by the oblique 

 posterior margin of the pectorals.

CYCLOPaETTA FIMBRIATA. 



AlKJut two-tiftlis niituralsize. 



In C. Jimhriata the scales are rather large and deciduous, the teeth 

 small, the anterior rays of the dorsal considerably produced, and the 

 l)osterior margin of the pectoral is subtruncate. It has been thought 

 well to publish a drawing of the type of the genus (see fig. 2) in this 

 paper. 



CYCLOPSETTA CHITTENDENI, new species. 



On April 4, 1892, the Museum received from Dr. John F. Chittenden, 

 of the Victoria Institute, Port of Spain, Triiiidnd Island, a single 

 specimen of the species here described as new and named in liis honor.

 D. 82; A. 02. Scales ca., 90. Gill-rakers 8+3 to 4, very short, tuber- 

 cular, almost as broad as long.
