DISCUSSION OF SPECIES AND THEIR DISTRIBUTION. 299 



ANARRHICHAS, Linnfeus. 



Anarrliichas, Autedi, Linn.eus, Syst. Xat., etl. x, 1758, i, 247 (typo, Anarrhlchas hipun, L.); ed. xil, 1766, n,

 Beax, Proc. U. S. Nat. Mua., ii, 1879, 212. 



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

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

 I)remasillary not protractile; jaws with very strong conical canines anteriorly; lateral teeth 

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

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

 series. Gill-membranes broadlv joined to the isthmus ; no lateral line. Dorsal fin rather 

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

 caudal flu developed, free from dorsal and anal; no ventral fins; pectoral fins broad, placed 

 low; air-bladder present; no pyloric cojca. {Jordan and Gilbert.) 



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

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

 of this species do not serve to distinguish it from A. latifrons. Tiie species known on the 

 American coast as A. latifrons is evidently the latifrons of Steenstrup' and CoUett,^ and we 

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



KEY TO THE SPECIES OF ANARRHICHAS. 



A. Banded species. 



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



A. LUPUS 



hh. Greenish, with 14 deep green cross-bauds; operculum having a green or blue spot; head, back, and 

 sides above mingled bluish and rod. Height of body contained about 5J times in its length. 



[A. FASCIATUS] 



AA. Species without bauds, 

 c. Spotted (in life). 



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



palatine '. A. MINOR 



cc. Uuicolored. 



e. Brown; D. 84; C. 17; scales none; nostril midway between eye and mouth; he.ad con- 

 tained 2J (!) times in total length; 6 canines in upper jaw [A. orientalis. Pacific] 



ee. Dark brown ; vomerine scries longer than palatine, and extends farther back ; D. 81 ; C. 

 20-21; scales few; nostril nearer eye than mouth; head contained 4i— 4f times in total 



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



dd. Brown, oliscurely 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, Llnnjsus. (Figure 269.) 



Anan-hichas lupus, Lin,n.eus, Syst. Nat., i, 1766, 430. — De Kay, Nat. Hist. N. Y., Fishes, 1842, 158, pi. x\i, 



fig. 43. 

 Anarrhiclias romerinus, Stoker, Hist. Fisli. Mass., 1867, 99, pi. xviii, fig. 1. 



This is a banded species, with a general hue of bluish gray, with 9-12 darker cross- 

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



On the New England coast it isft'cquent in the deep waters and approaching the shore, 

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