83. Rypticus coriaceus (Cope). Black Soap Fish. 



Eleutheractis coriaceus Cope, Trans. Am. Phil. Soc, 1870, 467 (St. Martins). 

 Rypticus coriaceus, Jordan & Evermann, Fishes of North America, 1,233. 



Several specimens 5 to 6 in. long. One has three opercular spines. 

 Aside from the number of opercular spines, this species may be dis- 

 tinguished from the preceding by its more slender body, depth 

 li to \\ in head, and by the less projecting lower jaw. 



PRIACANTHID^.

LUTIANID^. 



86. Neomaenis griseus (Linnaeus). 



Labrus griseus Linnaeus, Syst. Nat., Ed. X, 1758, 283 (after Catesby). 

 Lutj anus griseus, Jordan & Fesler, Sparoid Fishes, 441. 



Apparently none of the American Lutianince, unless it be Lutianus 

 viridis, are congeneric with the East Indian type of Lutianus. The 

 naked vertex with a band of scales at the temples is found in the 

 American forms, while in Lutianus the top of the head is evenly 

 scaled. There is also considerable difference in the skull in the 

 species compared. For the American forms, typified by Lutianus 

 griseus, the name Neomcenis Girard may be revived. 



87. Neomaenis jocu (Bloch & Schneider). 



Antkias jocu Bloch & Schneider, Syst. Ichth., 310, 1801 (Cuba, based on

Sparis apoda Walbaum, Artedi Piscium, 111, 1792 (after Catesby). 

 Sparus caxis Bloch & Schneider, Ichthyology, 284, 1810 (Havana, after 

 Parra). 



Lutjanus caxis, Jordan & Fesler, Sparoid Fishes, 443. 



Nearly uniform gray, more or less dark above, with faint yellow 

 lines on side ; body with about six pale cross streaks sometimes very 

 distinct ; one or two rows of small dots from below eye forward to 

 edge of preorbital ; pectorals pale yellow, ventrals white, caudal and 

 spinous dorsal dusky, soft dorsal and anal pale. Faded specimens 

 may be readily distinguished by the very distinct fleshy fold which 

 fits closely against end of maxillary.
