6. E. quappella E. and E., is known froma single specimen from 
Cu’Appelle, the northertinicst point from which darters are as yet cer- 
tainly known. It is related to E. iowe and to E. jessie. 
Diagnosis.—Premaxillaries not protractile ; gill membrane scarcely 
connected ; ventral line with the median scales not enlarged; lateral 
line straight, developed on 19 scales; palate without teeth; anal fin 
considerably smaller than soft dorsal; humeral region without black 
process; cheeks with a few scales just below and behind eye; opercle 
with a few scales on its upper angle. Head, 4; depth, 54; dorsal, 
IX-9; anal, 1, 6}; scales, 3-53-7.

The only companion of Coregonus coulterii in the snow water of the 
Kicking Horse at Field, B. C., was a species of Cottus, of which sev- 
enteen specimens were obtained. These are probably to be referred 
to the description quoted above. This species seems to be an inhab- 
itant of the cold waters of Alaska and to extend along the Rocky 
Mountains and the Sierras to Lake Tahoe, where it is replaced by 
Cottus beldingii. Specimens of the latter species are not now at hand, 
so that a direct comparison can not be made. 
Head proportionately longer in the adult, about 43-4 in head. D. 
VIII or [X-16 to 18; A. 11-13; V.14. Pectoral reaching anal or 
past vent even in the largest specimens. Anus equi distant from tip 
of snout and base of caudal or nearer tip of snout. Ashy gray, with 
blackish blotches; no well defined cross bars except sometimes on the 
tail. Frequently a dusky blotch on anterior part of spinous dorsal 
and another near its posterior end; the fin sometimes wholly dusky, 
margined with white; pectorals soft, dorsal and caudal more or less 
barr 
5. Cottus onychus E. and E. 
Type.—A single specimen 82 mm. long; Calgary. 
This species is evidently closely related to C. pollicaris J. and G., 
from which it differs chiefly in having many prickles. 
Head, 34; depth, 63; D. VIII, 17; A., 13; VLt: PIs Tooth 
on vomer, none on palatines. Width of head equals its length to end 
of preopercular spine, its depth 2 in its length. Preopercle with an 
upturned claw-like spine, below which are two others much smaller, 
the anterior one having its point turned downward and forward. 
Eye 14 in snout, 4 in interorbital, 44 in head. Lower jaw projecting,
