DISCUSSION OF SPECIES AND THEIR DISTEIB1 TION. 299 



ANARRHICHAS, Linnseus. 



linarrhichas, Akiedi. Linn^us, Syst. Nat., od. x, 17.".*, i, l'17 (tj pe, Inarrhichas lupus, I-.): ed. xn, 1766, n, 

 130.— G&nther, Cat. Pish. Brit. Mus., in. 208.— Jordan and Gilbert, Bull, xvi, U.S. Nat. Mns., 781.— 

 Bean, I'roc. U. S. Nat. Mus., a, 1879, 212. 



Body moderately elongate, covered with rudimentary scales ; head scalcless, without 

 cirri, compressed, narrowed above, the profile strongly decurved; mouth wide, oblique; 

 premaxillary noi protractile; jaws with very strong conical canines anteriorly ; lateral teeth 

 of lower jaw either molar or with pointed tubercles; upper jaw withoul lateral teeth: vomer 

 extremely thick and solid, with 2 series of coarse, molar teeth; palatines with 1 or 2 similar 

 series. Grill-membranes broadly joined to the isthmus; no lateral Hue. Dorsal fin rather 

 high, composed entirely of flexible spines, which are enveloped in the skin; anal fin lower; 

 caudal lin developed, tree from dorsal and anal; no ventral fins; pectoral fins broad, placed 

 low; air-bladder present; no pyloric ececa. [Jordan and Gilbert.) 



A key to the species of Ana/rrhiehas, prepared by Dr. Bean, is given. In this no ref- 

 erence is made to A. denticulatus of Kroyer, because the slight descriptions which we have 

 of this species do uot serve to distinguish it from A. latifrons. The species known ou the 

 American coast as A. latifrons is evidently the latifrons of Steenstrup 1 and Collett, 2 and we 

 cau not see that it differs from A. denticulatus of Giiuther 3 or of Kroyer. 4 



KEY TO THE SPECIES OF ANARRHICHAS. 



A. Banded species. 



b. Bluish gray, with 9-12 darker cross-bands. Vomerine teeth extend farther hack than the palatine. 



A. LUPUS 

 bb. Greenish, with 11 deep green cross-hands; operculum having a green or blue spot; head, back, and 

 sides above mingled bluish ami red. Height of bod; contained about 5| times in its length. 



[A. FASCIATUS] 

 AA. Species without bauds. 

 c. Spotted (in life). 



d. Many large, round, black spots. Vomerine teeth extend nearly or quite as far back as the 



palatine A. minor 



cc. Gnicolored. 



e. Brown; 1>. 84; C. 17; scales none; nostril midway between eye and mouth; head con- 

 tained 2b (!) times in total length; 6 cauiues in upper jaw [A. oiuentalis. Pacific] 



ee. Darkhrown; \omeriue series longer than palatine, and extends farther back; D. 81; C. 

 20-121; scales few; nostril nearer eye than mouth; head contained 4 .J— if times in total 



length; 1 canines in upper jaw [A. lepturus. Alaska] 



dd. Brown, obscureh spotted with darker; vomerine teeth do not extend nearly so far back as the 

 palatine A. LATIFRONS 



In the measurement tables which follow the hundredths of length are calculated from 

 the total length without the caudal. 



ANARRHICHAS LUPUS, Lixx.uus. (Figure 269.)

fig. 43. 

 Anarrhichat vomerinw, Storer, Hist. Fish. Mass., 1867, 99, pi. xvm, fig. 1. 



This is a bauded species, with a general hue of bluish gray, with 9-1:3 darker cross- 

 bands. The vomerine teeth extend farther back than the palatines. 



On the Xew England coast it is frequent in the deep waters and approaching the shore, 

 particularly in winter. It is associated with many deep-water forms.
