G82 COXTEIBUTIONS TO NOETH AMEEICAN ICHTHYOLOGY IV. 
360.— SETARCHES Johnson. 
(Johnson, Proc. Zool. Soc. Loud. 1862, 11: type Seiarches Johnson.) 
As here understood, this genus differs from Seorpccna in having less 
than 12 dorsal spines and the scales cycloid, without skinny flaps. 
Deep-sea fishes. Our species differs from S. giintheri in the possession 
of but ten dorsal spines instead of eleven. (Etymology not obvious.) 
1039. S. parmatMS Goode. 
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 develojied about as in Se- 
hastes. Preopercular spines very long; caudal truncate. Pectoral flu 
long, 21 in body. Head 2^; depth 2f. D. X, C + ; A. Ill, 6. [Goode.) 
Deep water off' Ehode Island; known from a young specimen. 
(Goode, Proc. U. S. Nat. Mus. 1830, 480.) 
Family CVII («). — COTTID^. 
{The Sciilpins.) 
Body moderately elongate, fusiform or compressed, tapering back- 
ward from the head, which is usually broad and depressed. Eyes 
placed high, the interocular space usually narrow; a bony stay con- 
necting the suborbital wdth the preopercle, usually covered by the skin; 
ui)per angle of preopercle usually with one or more spinous processes. 
Teeth equal, in villiform or cardiform bands on jaws, and usually on vo- 
mer and italatines; premaxillaries protractile; maxillary without supi^le-- 
mental bone. Gills 34 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 spines; pectoral 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. Pseudobran chioe present, at least in all our species. 
Pyloric coeca usually in small number (4-8); air-bladder commonly 
wanting. Genera about 40; species about 150, mostly of the rock pools
