Uniformly purplish black, somewhat paler on the belly. The 

 body is elliptico-oblong and much compressed, the height, compared 

 with the total length, being as 1 to A\, and the length of the head 

 to the total length as 1 to 5. 



The head is scaleless above, gelatinous, punctate, and arched. 

 The snout is abbreviate and abrupt, but does not form a quadrant 

 with the head, as is the case in S. Berthelotii. The opercle and sub- 

 opercle are scaly and striate, the striae ending at the margin in mi- 

 nute teeth. The preopercle is scaleless, the border being striate, 

 and the striae projecting as blunt teeth*. The eye is round, its 

 centre is placed about the middle of the height, and it is surrounded 

 by radiating grooves ; it is contained five times in the head ; the 

 space between it and the tip of the snout is equal to a diameter and 

 a half. The mouth is of moderate size, and the jaws are equal ; 

 each is set with a single series of small sharp teeth. There are no 

 teeth on the palatines or the vomer. The tongue is broad, smooth, 

 and white. 



The long scaly dorsal fin commences behind the root of the pec- 

 toral fin ; it is low in front, highest at the middle, and has an angular 

 termination. The spinous rays are not to be distinguished from the 

 others. The pectoral fins are pointed, and have broad roots ; they 

 are inserted below the middle of the height, and their fourth and 

 fifth rays are the longest ; they scarcely reach more than halfway 

 to the vent. The pointed ventral fins are inserted near together, 

 just under the posterior angle of the root of the pectoral fins. The 

 second soft ray is the longest ; this fin does not reach halfway to 

 the vent. The scaly anal fin is high in front and pointed behind ; 

 it terminates opposite, or perhaps a little behind, the termination of 



* In describing S. Berthelotii (Ichth. Canarienne, p. 45), M. Valenciennes says 

 that the opercle, subopercle, and interopercle are not scaly, whereas all the oper- 

 cular pieces are most certainly scaly.
