DISCUSSION OF SPECIES AND THEIR DISTRIBUTION. 309 



paxillus being only a fifteenth <>!' the total length, while in zoarchus it is one-ninth. The 

 head in pcucillus is one seventh of the total length, while in this species its Length is con 

 tained 5jj times. The coloration is also very different from thai of paxillus, t lie la iter being 

 a uniform brown, while zoarchus has a black blotch at the beginning of the dorsal, and the 

 sides are irregularly mottled with dark markings, which in the young specimen form more 

 or less complete bands, while iii adult specimens these bands break up into irregular 

 mottlings. 



LYCENCHELYS, Gill. 



Lyeenehelys, Gill, Proc. Acad. Nat. Soi., Phila., L884, 180. 



A genus closely allied to Lycodes, but baying a very elongate body, its length being 

 from twelve to twenty-four times its height. 



LYCENCHELYS .MUM'.vy (( ollett), Gill. 



Lycodes murwna, Collett, Forh. sdsk. Christ., 1878, X". it, 15. 

 Lyeenehelys murcena, Gill, loe. oit. 



A Lycenchelys with body extremely elongate and slender; its greatest height cou- 

 t a hied about I'll times, length of head nearly 8 times in the total length. The long diameter 

 of the eye is contained about 4A- times in the length of the head. Body everywhere scaled, 

 head and tins naked. Ventrals comparatively close together, contained (> times in the length 

 of the pectoral. Teeth in a single scries in both jaws. Color (in the single young individ- 

 ual examined > uniform -ravish brown.

Lateral line present, but difficult to trace in its entirety. From the upper angle of the 

 gill-opening a series of rather closely placed, very small pores (connected by a narrow line), 

 descends in a curve to a short distance behind the vent; after having reached nearly to the 

 base of the anal, it runs for a short distance nearly horizontally, whereupon it ceases, or 

 can not be followed in the same direction with certainty. Another lateral line, however, 

 begins about over the vent, and runs horizontally along the median line, becoming obsolete 

 toward the end of the tail. The pores herein are very small and more widely separated, and 

 can be seen only by close observation ; the short whitish line which runs through each pore, 

 forms here no accompanying line. 



Since the termination of the anterior descending lateral line is considerably behind the 

 origin of the upper horizontal lateral line, no connection appears to exist between them.
