1778. CYNOSCION JAMAICENSIS (Vaillant & Bocourt). 

 (MONGOLAR DRUMMER.) 



Head 3 ; depth 3| (4f with caudal) ; eye 4 in head. D. X-I, 26 or 27 ; A. 

 1, 9 ; scales 63 ; snout 3f in head, longer than eye ; maxillary to below middle 

 of pupil, 2 in head ; lower jaw projecting ; depth of head over hinder mar- 

 gin of eye, If in its length. A single large canine in front of upper jaw, 

 4 or 5 small teeth on side of lower jaw, other teeth few and small; 

 tongue free at end and sides, with a broad median groove; slit of poste- 

 rior nostril nearly vertical. Gill rakers 3-J-7, the longest \ eye. Opercu- 

 lar flap extending beyond upper base of pectoral; preopercle with a 

 membranous margin. Dorsals contiguous; membrane of anal scaled 

 almost to tip, that of dorsal about halfway. Scales weakly ctenoid, 

 those on top of head irregular in size. Pectorals about equal in length 

 to ventrals, 1| in head; caudal doubly concave, middle rays longest. 

 Curve of lateral line gradual, becoming straight behind the fourth dorsal 

 ray. Color in alcohol, very dark olive above, the entire sides with golden 

 luster, paler below; dorsals, pectorals, and caudal lightly punctate, 

 lower fins colorless. This species is closely related to Cynoscion obliquatus, 

 differing in having the caudal doubly concave, and the anal with but 9 

 rays, and especially in its much more robust form. Jamaica. Here 

 described from 4 specimens 8 to 10 inches long, sent us by Rev. Joseph 

 Seed Roberts, of Kingston, Jamaica.

1779. CYNOSCION NOTHUS (Holbrook). 

 (BASTARD WEAKFISH.) 



Head 3-|; depth 3|; eye 4; snout 44-. D. X-I, 27 to 29; A. II, 9 or 10; 

 scales 6-58 to 62-7. Caudal weakly double concave ; body rather deep ; 

 eye very large, equal to interorbital width; body more compressed than 

 in other species, the back somewhat elevated ; snout rather short, not very 

 acute, mouth smaller than in related species; maxillary 2-J- in head, reach- 

 ing to below posterior margin of pupil ; gill rakers long and slender, 4-J-9, 

 the longest ieye; lower pharyngeals very slender ; dorsal fins contigu- 

 ous ; membrane of soft dorsal scaled to its tips ; scales weakly ctenoid ; 

 lateral line much curved anteriorly, becoming straight under seventh 

 dorsal spine. Color grayish silvery, thickly punctulate above and on 

 sides to level of pectorals, then abruptly silvery, a row of dark points 



*The following is the substance of the original account of Cynoscion jamaicensis : 

 Head 4; depth 4*. D. X-I, 25; A. 11,9. Scales 6-59-18. Body moderately elevated; 

 lower .jaw projecting; snout nearly 3 in head ; maxillary reaching nearly to opposite mid- 

 dle of eye; eye equal to interorbital space, 4 in head; preopercle rounded; scales moder- 

 ate; lateral line rising anteriorly almost to upper fourth of depth of body, becoming 

 median under fourth soft ray of dorsal; soft dorsal scaly. Vent at end of third fifth of 

 total length. Dorsal spines' feeble, the fourth longest, "nearly head; anal spines very 

 weak, the second H in eye; pectoral If in head, reaching tips, of ventrals. Caudal 

 shortish, the middle rays longest. No pseudobranchia> (in type). Color plain silvery in 

 spirits, without markings. 

 Jamaica; one specimen m. 240 in length. (Vaillant & Bocourt.)
