REPORT ON THE DEEP-SEA FISHES. 81 



Lycodes paxillus. 



Lyeodes paxillus, Goode and Bean, Proc. U.S. Nat. JIus., 1880, vol. ii. p. U; 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. 



Lycodes paxilloides, Goode and Bean, Bull. ;Mus. Comp. Zool., 1883, vol. x. p. 207. 



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

 466 fathoms. 



Lycodon us. 

 Lyrodonus, Goode and Bean, Bull Mus. Comp. Zoiil., vol. x., 1883, p. '208. 



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 present. Gill-opening narrow ; branchios- 

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

 apparently present. Gill-rakers present, in moderate number. Air-bladder and pyloric 

 coeca apparently absent. 



lyycodonus mirahilis. 



Lrjcodonvs mirdbilis, Goode and Bean, Bull. Mu.s. 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 sj^ecimen, measuring 4j 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. 



Gymnelis, Reinh. 



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

 from the Straits of Magellan. 



■ I think Hr. CoUett is in error when he identifies Gymnelis picta (GUnth., Fish., vol. iv. p. 324 and Proc. Zool. Soc. 

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

 number of its fin-rays. The change of colour, wliich takes place during growth, seems to be common to (liimnelU, 

 Maynea, and some species of Lycodes, and cannot be held as evidence of specific identity.
