PROCEEDINGS OF UNITED STATES NATIONAL MUSEUM. 59 
Lateral line deflected downwards suddenly at posterior extremity of 
second dorsal, thence posteriorly along center of caudal peduncle, and 
anteriorly parallel to dorsal outline; pores simple, 35-37. 
Body sealeless, entirely smooth. 
Color olivaceous above, lighter below; upper portion maculated with 
darker; fins with small dark spots on the membrane; a dark band 
across caudal. 
Two specimens (Nos. 1 and 3) from fresh water, near Saint Paul’s, 
Kodiak, collected by W. J. Fisher. In No. 1 the dorsals are separated 
by a considerable space; in No. 3 by a smaller space. One of these is 
in the United States National Museum, numbered —. 
Numerous specimens from the Aleutian Islands, collected by Captain 
Greenebaum, present no difference except in the more or less complete 
union of the dorsals, and their smaller size. The latter are probably 
half grown. 
As the fin-rays and other characters agree closely, I am inclined to 
think the separation of the dorsals either an individual character, or 
one due to greater age. 
Mr. Fisher’s examples were obtained in fresh-water lakes formed by 
the melting snows, and communicating with the ocean only by shallow 
outlets. This species differs from those of the genus found in the 
United States by its smaller mouth, lower fins, and the four soft rays 
in the ventrals. In all these respects it resembles the European Ura- 
nidea gobio.
