New Species of Cuban Fish. 



notched, fmely denticulated ; the opérele witliout a spinous 

 point. The teeth are on one row, the canines rather long, and 

 behind them there are asperities ; the palatine arch has teeth, 

 and the tongue is rough. The lateral line has about fifty-five 

 scales, six rows above and fifteen below it; there are scales on 

 the opéreles and temples, the rest of the head naked. The 

 scapular bones show outside. There are very small scales on 

 the interstitial base of the soft rays of the vertical fins. D. 10, 

 14 ; A. 3, 8. 



The posterior borders of the dorsal and anal are rounded ; 

 the caudal lobes are elongated, but less so than in the M. 

 chrysurus / the pectoral is pointed, contained four and a half 

 times in the total lengtb. The three first spiny rays of the 

 dorsal gradually increase in length, the last, or tenth one, not 

 longer than the precediog ones. The soft rays of the dorsal 

 and anal are all branched and flattened. 



The color is a brownish green, the abdomen paler. Six 

 brown bands fall vertically from the back over the sides ; a broad 

 and interrupted stripe, of a greenish color, extends from the 

 upper part of the opérele to the base of the caudal, resembling 

 the Ocyurus chrysurus and aurovittatus. 



I have seen this fish but once, and I sent the specimen to the 

 United States, either to Prof. Agassiz or to Mr. Brevoort. It 

 bears my No. 163. 



Oymnothorax obscuratus, Poey. 



I found this fish but once in Ha vana, and sent the specimen 

 to Prof. Agassiz, to add to the rich ichthyological collections 

 which he has gathered in Cambridge. It is one of the same 

 group to which belong the species infernalis, erebus, rostratus, 

 etc., in my Synopsis. 



It is 618 mm., or 24.33 inches long ; the .anterior portion of 

 the body forming the trunk being to the caudal portion as one 

 to one and a third (270 + 348), which last is gradually more and 

 more compressed. The length of the head to the branchial
