below lateral line not numerous, about ten large and perhaps twice as many small 
ones; cheek with two or three small dark spots and numerous line punctulations; a 
few small spots on top of head; dorsal fin with about a dozen small spots or blotches; 
adipose fin dark-edged; caudal fin well spotted, the spots more or less evidently 
arranged in five vertical rows; other fins plain; tip of lower jaw dark. 
A specimen, 7 inches long, from the same place, differs from the smaller one in 
having the large vertical blotches less distinct, and the other spots more numerous, 
especially on dorsal, adipose, and anal fins, and on toil of head; the spots on the cheeks 
are also less distinct. 
Twenty specimens, each about 44 inches long, from Atlantic Creek in Two-Ocean 
Pass, show no marked ditterences from those from McClellan Creek. The spots are a 
little larger in some specimens ; the large blotches seem a little less distinct than in the 
larger, but much the same as in the smaller specimen from McClellan Creek. Those 
from Atlantic Creek are a little more slender than the others. 
A specimen 2§ inches long, from Atlantic Creek, about one mile from its mouth, 
does not differ in color from those taken in the same creek at Two-Ocean Pass. 
Sixteen specimens, 4 to 6£ inches long, from Pacific Creek, in Two-Ocean Pass, 
can not be distinguished from those of the same size taken in Atlantic Creek, a few 
yards away. 
Three examples taken in Pacific Creek, about 7 miles below the pass, and meas- 
uring 54 and 64 inches in length, have the spots less numerous and larger, agreeing in 
this with the Atlantic Creek specimens. 
A specimen 14 inches long from Pacific Creek, about 25 miles below the pass, 
presented the following life colors : Above, dark greenish, very dark on head, lighter 
posteriorly ; paler on sides, nearly white on belly, but with some dark washings. No 
spots on top of head, very few on body in front of dorsal, more numerous behind; ten 
or eleven small round spots on cheek. Sides of head with red or pinkish wash, old 
gold at upper edge of opercle and a blotch of the same behind the eye. Shoulder 
above pectoral reddish; throat white, with red gash; rim of lower jaw washed with 
dark. Pectorals dark wine color ; ventrals and anal red. Spots on body nearly round. 
Another specimen, 114 inches long, from same place, was, in life, dark-greenish 
above, silvery on the sides, but with an underwasli of yellowish; belly white; few, if 
any, spots on head or on back in front of dorsal, and but few on anterior half of body, 
while they are rather thick under the dorsal and quite thick along the back between 
the dorsal and caudal fins ; not over fifty spots altogether below* the lateral line; dorsal 
and caudal fins well spotted; two dark blotches on cheek; opercles pinkish, yellowish 
at top ; red gash on throat not heavy ; pectorals dark, ventrals and anal yellow. 
Another specimen, 12 inches long, was yellowish like the one just described, but 
had the spots more numerous and not so nearly round, each spot being made up of 
two or more short black lines joined in such a way as to make the spots appear 
somewhat star-shaped at first glance. 
An examination of about thirty large individuals from this place seemed to show 
that they may be separated into two groups : one more slender, and yellowish in color ; 
the other less slender and with little or no yellow. The star-shaped spots seemed to 
be more common among the yellow examples, but all were not so marked, nor was 
this style of marking absent from the other form.
