Eyes and color on the right side (except in P. stellatus, which is indif- 
ferently dextral or sinistral). Body ovate, elliptical, compressed; head 
moderate, sometimes tnberculate; mouth small, the small, narrow max- 
illary reaching front of eye or beyond; blind side with one (rarely two) 
series of close-set, conical or incisor-like teeth ; colored side of both 
jaws usually toothless. Scales small, ctenoid or cycloid, often imper- 
fectlj* imbricated, sometimes tubercular or obsolete. Lateral line 
nearly straight, or more or less arched anteriorly, simple, or with an 
accessory branch. Gill-rakers small, widely set. Species very numer- 
ous in northern seas. {-Xsupw, side; vrjzr-gg, swimmer.) 
a. Lateral line with an accessory dorsal branch, long or short. 
b. Lateral line straight or with a slight arch.

Uniform light olive brown ; the young somewhat spotted with 
blackish. Body elongate-elliptical; snout very prominent, much pro- 
truding, forming an abrupt angle with the descending itroflle; depth 
of head opposite middle of upper eye about equalling distance from 
middle of orbit to snout; eyes large, separated by a very narrow, high 
* If we were to attribute to some of the characters the same generic value as in 
other Pleuroneclidce, we should be obliged to establish a genus for almost every species, 
and to separate lishes which evidently form one natural group” (Giiniher, iv, 438). 
The curvature of the lateral line is here subject to much variation ; the accessory 
lateral line, characteristic of so many Pacific species, disappears by degrees, while the 
gradations in dentition and squamation are .so numerous as to be apparently useless 
for generic chai’acters. We are unable to follow Dr. Giinther in referring to Plcuronee- 
tea, the species of Glyptoceplmlua and Cynicogloaaiia, which seem to us to represent a 
well-differentiated type.
