352 REVIEW OF SPECIES OF BELONID^. 



erately prominent, coarsely striate. Vertex tlattisli, not depressed. 

 Temporal ridge without distinct notch behind eye. Two parallel ridges 

 on each side of occiput. No fold of skin across preopercle on lower 

 posterior margin. 



Cheeks covered with small scales in about 16 rows ; opercle covered 

 with similar scales which are scarcely smaller. 



iSTo gill-rakers. 



Dorsal tin of moderate length and height, the posterior rays low, 

 even in young specimens, the anterior lobe 1^ in postorbital ijart of 

 head ; base of the fin equal to eye and postorbital part of head. 



Anal a little higher than dorsal, and beginning a little farther for- 

 ward. 



Caudal slightly lunate, the middle rays a little shorter than upper ; 

 the lower a little produced, a little longer than i)Ostorbital part of head. 



Pectorals equal to postorbital part of head. Ventrals 1^ in post- 

 orbital part of head, their insertion midway between origin of middle 

 caudal rays and edge of preopercle. 



Color, clear greenish above, sides and below silvery; a narrow, 

 bluish silvery lateral streak, less distinct than in T. subtruncatus and T. 

 notatus, becoming wider and usually fainter under the dorsal. This 

 stripe is usually plainer in young examples. A conspicuous dark bar 

 on front of opercle. A dark median strij)e on back. Fins dusky 

 olivaceous, with no distinct black markings. Axil dusky. 



The synonymy of this species oflers little room for doubt. The de- 

 scription given by Bloch & Schneider amounts to nothing, but such as 

 it is, it is drawn from Schopf, and no doubt seems to exist as to what 

 Schopf had in mind. 



The synonymy, as well as the description given by Dr. Giinther, in- 

 dicates the confusion of this species with others, especially with T. 

 almeida. ~^o other author seems to have recorded T. marinus from the 

 West Indies, and we question its occurrence there. It is not found at 

 Key West or Havana.
