DISCUSSION OF SPECIES AND THEIR DISTRIBUTION. 309 



paxilhis being ouly a fifteenth of tlie total length, while in ::oarehus it is one-ninth. The 

 head in 2)nxillus is one-seventh of the total length, while in this species its length is con- 

 tained ■'>'?! times. The coloration is also very different from that o{ parilliis, the latter 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, whicli in the young specimen form more 

 or less complete bauds, while in adult specimens these bauds break up into irregular 

 mottlings. 



LYCENCHELYS, Gill. 



LycencheJya, Gill, Proc. Acad. Nat. Sci., Phila., 1884, 180. 



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

 from twelve to twenty-four times its height. 



LYCENCHELYS MUR^NA, (CoLLETr), Gill. 



Lycodes munena, Collett, Forh. Selsk. Christ., 1878, No. 14, 15. 

 Lycenchelijs miirtrna, Gill, loe. cit. 



A Lycenclielys with body extremely elongate and slender; its greatest height con- 

 tained about 20 times, length of head nearly 8 times in the total length. The long diameter 

 of the eye is contained about -ii times iu the length of the head. Body everywhere scaled, 

 head aud fins naked. Veatrals comparatively close together, contained G times iu the length 

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

 ual examineil) uniform grayisli brown.

Lateral line present, but difficult to trace iu its entirety. From the upper augle of the 

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

 descends in a curve to a sliort 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 iu 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 eud 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 uo 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.
