Habitat.—All northern seas, southward in deep water to France, 
Sandy Hook, and San Francisco. 
The halibut, the largest and most widely distributed of all the 
Pleuronectide, is too well known to require discussion here. 
Genus I[V.—LYOPSETTA. 
Lyopsetta Jordan and Goss, Cat. Fish. N. A., 1885, 135 (exilis). 
Type: Hippoglossoides exilis Jordan & Gilbert. 
This genus contains but asingle species, a small, soft-bodied flonndet, 
of the waters of the North Pacific. In its Agate characters Lyop- 
setta is very close to Hippoglossoides, of which it might well be regarded 
a subgenus. The introduction of the name Lyopsetia is to be regretted 
from its close resemblance to Liopsetta, a word of similar sound, but 
very different meaning. At the time of the introduction of Lyopsetta, 
Tiopsetta was regarded as an obsolete synonym. 
ANALYSIS OF SPECIES OF LYOPSETTA.
