ANARRHICHAS, Linnpeus. 



Aiian-hichas, Artrdi, Linn.eus, Syst. Nut., t»\. x, 1758, i, 247 (typo, AnarrhicJmn hipiiK, L.) ; c<l. xii, 17GG, n,

 Bean, Proc. U. S. Nat. Mus., ii, 1879, 212. 



Body moderately elongate, covered with rudimentary scales; head scalcless, witLout 

 cirri, compressed, narrowed above, the prohle strongly deciirved; mouth wide, oblique; 

 premaxillary not protractile; jaws with very strong conical canines anteriorly; lateral teeth 

 of lower jaw either molar or with pointed tubendes; upper jaw without lateral teeth; vomer 

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

 series. Gill-membraues broadlv joined to the isthmus; no lateral line. Dorsal fln rather 

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

 caudal flu developed, fi*ee from dorsal and anal; no ventral tins; pectoral fins broad, placed 

 low; air-bladder present; no pyloric cteca. (Jordan ;\uil Gilbert.) 



A key to the species of Anarrhichas, prepari^d by Dr. Bean, is given. In this no ref- 

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

 of this species do not serve to distinguish it from A. lafifrons. The species known on the 

 American coast as A. hitifrons is evidently the latifrom of Steeustrup' and Oollett,'^ and we 

 can not see that it differs from A. dentlculntiis of Giinther^ or of Kroyer.* 



KEY TO THE SPECIES OF ANARRHICHAS. 



A. Banrted species. 



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



A. Lri'us 

 66. Greeaisli, with 14 deep green cross-bands; operculum having a green or blue spot; head, back, and 

 sides above mingled Ijluish and red. Height of body contained about SJ times in its longtii. 



[A. FASCIATUS] 



AA. Species without bands, 

 c. Spotted (in life). 



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



palatine A. MixoR 



cc. Unicolored. 



c. Brown; I). 84; C. 17; scales none; nostril midw.ay l)etwecu eye ami mouth; head con- 

 tained 2^ (!) times in total length; 6 canines in upper jaw [A. ORIENTali.s. P.acific] 



ce. Dark brown ; vomerine series longer than i)alatiue, and extends farther back ; D. 81 ; C. 

 20-21; scales few; nostril nearer eye than mouth; head contained 4A-4| times in total 



length; 4 canines in upper jaw [A. lepturo.s. Alaska] 



dd. Brown, obscurely .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, Lin.n.kus. (Figure 269.) 



Anarrhichas lupus, Linn.eus, Syst. Nat., i, 1766, 430.— 1)e Kav, Nat. Hist. N. Y., Fishes, 1842, 158, pi. xvi, 



fig. 43. 

 Anarrhichas romcrinus, Stoker, Hist. Fish. Mass., 1867, 9!), pi. xviii, tig. 1. 



This is a banded species, with a general hue of bluish gray, with 0-13 darker cross- 

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



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

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