Lycodes paxillus. 



Lycodes paxillus, Goode and Bean, Proc. U.S. Nat. Mu,^., 1880, vol. ii. p. 44; 1881, p. 477. 



Known at first from a single specimen, 14| inches long, which was caught on the 

 Le Have Banks in about 300 fathoms, and subsequently from others obtained off the New 

 England coast in 365 and 487 fathoms.

Lycodes paxilloides. 



Lijcoiles paxilloides, Goode aud Bean, Bull. ilus. Conip. Zool., 1883, vol. x. p. 207. 



Obtained by the U.S. steamer "Blake" off the coa.st of Massachusetts in from 304 to 

 466 fathoms. 



Lycodon us. 



Lyeodonw!, Goode and Bean, Bull. Mus. Comp. Zool., vol. x., 1883, p. l'08. 



Form of a slender Lycodes. Body with rudimentary scales ; each ray of the dorsal 

 and anal supported laterally by a pair of sculptured scutes. Caudal distinct, not fully 

 connate with the other vertical fins. Ventrals jjresent. Gill-opening narrow ; branchios- 

 tegal membranes broadly joined to the isthmus. Teeth as in Lycodes. Pseudobranchia^ 

 apparently present. (Jill-rakers present, in moderate numlicr. Air-bladder and pyloric 

 coecn apparently al)sent. 



Lycodonus m indjilis. 



Lycddonut! wifahiUs, Goode and Bean, Bull. Mus. Comp. Zoiil., vol. x., 1883, p. 208. 



The eye is two-fifths of the length of the head ; the maxillary reaches to the front of 

 the pupil. The dorsal fin commences somewhat behind the base of the pectorals. 



A single mutilated specimen, measuring 4.^ inches in its imperfect condition, was 

 obtained by the U.S. steamer " Blake," in lat. 38" 20' N., long. 73° 23' W., at a depth of 

 470 fathoms. 



(jlymnelis, Reiidi. 



Two species' only are known; one from the Arctic Ocean, the other (Gymnelis picta) 

 from the Straits of Magellan. 



o 



' 1 think Hr. Collett is in error when he identilics Gymnelis picUi (Giinth., Fish., vol. iv. p. 324 and Proc. Zool. Soc. 

 Land., 1881, pi. ii. tig. b) with Gymnelis viridis; it is very likely an Antarctic species, well distinguished by the 

 number of its fin-rays. The change of colour, which takes place during growth, seems to be common to Gymnelis, 

 Maynea, and souie species of Lycodes, and cannot be lield as evidence of specific identity.
