682 CONTEIBUTIONS TO NORTH AMERICAN ICHTHYOLOGY IV. 



360.— SETARCHES Johnson. 



(Johnson, Proc. Zoiil. Soc. Lond. 1862, 11: type Seiarclies giintheri Johnson.) 



As here understood, this genus ditfers from Scorpcena in having less 

 than 12 dorsal spines and the scales cycloid, without skinny flaps. 

 Deep-sea fishes. Our species differs from 8. gUnfheri in the possession 

 of but ten dorsal spines instead of eleven. (Etymology not obvious.) 



1039. S. pacBiiatus Gooile. 



Body stout and deep. Fins high; vertical fins inserted well back, 

 the paired fins well forward. Interorbital width half the length of the 

 upper jaw, about equal to the orbit. Eye moderate, nearly 4 in head. 

 Scales comparatively large, regularly arranged, cycloid, with concentric 

 furrows and no dermal flaps. Cranial ridges developed about as in Se- 

 bastes. Preopercular spines very long; caudal truncate. Pectoral fin 

 long, 21 in body. Head 2^; depth 2f. B. X, C + ; A. Ill, 6. [Goode.) 

 Deep water off Rhode Island; known from a young specimen. 



(Goode, Proc. U. S. Nat. Mus. 1880,-480.) 



Family CVII («).— COTTID^. 

 {The Sculjnns.) 



Body moderately elongate, fusiform or compressed, tapering back- 

 ward from the head, which is usually broad and dejiressed. Eyes 

 placed high, the interocular space usually narrow; a bony stay con- 

 necting the suborbital with the preopercle, usually covered by the skin; 

 upper angle of preopercle usually with one or more spinous processes. 

 Teeth equal, in villiform or cardifonn bauds on jaws, and usually on vo- 

 mer and palatines; i)remaxillaries protractile; malillary without supple- 

 mental bone. Gills 3^ or 4; slit behind the last gill small, or obsolete; 

 gill-rakers short, tubercle-like or obsolete; gill-membranes broadly con- 

 nected, often joined to the isthmus. Body naked, or variously armed with 

 scales, prickles, or bony plates, but never uniformly scaled. Lateral line 

 present, simple. Dorsal fins separate or somewhat connected, the spines 

 usually slender, the soft part elongate; caudal fin separate, rounded; 

 anal fin similar to the soft dorsal, without sx^ines; i^ectoral fins large, 

 with broad procurrent bases, the rays mostly simple, the upper some- 

 times branched; ventrals thoracic, rarely entirely wanting, the rays usu- 

 ally less than 1, 5. Pseudobranchife present, at least in all our species. 

 Pyloric cceca usually in small number (4-8); air-bladder commonly 

 wanting. Genera about 40; species about 150, mostly of the rock pools
