1. Dussumieria stolifera. 



Body elongate, slender, moderately compressed, with the shape and 

 general appearance of slender species of Stolephorus ; belly not com- 

 pressed to an edge. Snout very sharp, tapering, the jaws equal; cleft 

 of mouth little oblique, the maxillary reaching slightly beyond front of 

 eye, about 2 J in head. Teeth minute, but evident in both jaws. Eye 

 large, 2^ in head. Insertion of dorsal slightly nearer tip of snout than 

 base of caudal ; the fin high, the longest ray two-thirds length of head. 

 Insertion of ventrals under fourth or fifth ray of dorsal. Anal low. Yen- 

 trals nearly half as long as head, slightly shorter than pectorals, which 

 do not reach their base. 



Head 3|in length; depth 5J. D. 11; A. 17. Scales rather large, ca- 

 ducous, probably about 36 in a longitudinal series, judging from the 

 impressions on the skin. 



Color.— Translucent green, pale below; sides with a well-defined 

 silvery baud as in Atherina or Stolephorus, about one-fourth depth of 

 body and a little broader than pupil; a double row of dots along back 

 before dorsal fin, and a single row behind dorsal; fins plain. 



Very abundant in schools in the surf about Key West, in company 

 with Stolephorus hrowni. All the specimens seen were of about the 

 same size, about If inches in length. It is probable that it does not 

 attain a larger size. 



We should identify our specimens with Clupea lamprotcenia Gosse, 

 from Jamaica, were it not for the difference in the numbers of fin rays. 

 2 Tylosurus sagitta. 

 Very closely allied to Tylosurus scajmlaris J. & G. 

 Body slender, not compressed, as broad as deep ; caudal peduncle 

 not strongly depressed, its depth about equaling its width ; no keel on 

 caudal peduncle ; the lateral line not black, and not more conspicuous on 

 tail than elsewhere. 



Jaws slender, of moderate length, the upper jaw from eye contained 

 ^ times in length, and containing length of rest of head I4 times. Di- 

 ameter of eye about 1^ in interorbital width, 2^ to 3 in postorbital part 

 of head, about 7i in upper jaw forward from eye.
