DISCUSSION OF SPECIES AND THEIR DISTRIHUTION. 309 



paxUlits being only a fifteenth nf the total length, while in zoarchiiti it is one ninth. The 

 head iin)a.rillus is one-seventh of the total length, while in this si)C(;ies its lengtli is con- 

 tained ')% times. The coloration is also very different from that o{]>ii.vill>(s, the latter being 

 a nuiform brown, while zoarchm has a black blotch at the beginning of the dorsal, and the 

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

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

 mottlings. 



LYCENCHELYS, Gill. 



Lycencheli/s, Gill, Proc. Acail. Nat. Sci., Phil.a., ISSl, 180. 



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

 from twelve to twenty-four times its height.

\ Lyccnchrh/s witli 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 4i times in the length of the head. Body everywhere scaled, 

 head and fins 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 grayish brown.

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

 gill-opening a series of rather do.sely 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 (-eases, 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, Ijecoming obsolete 

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

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

 forms here no accompanying line. 



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

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