NOTES ON A COLLECTION OF FISHES MADE IN ISS2 AND 1883 
BY CAPT. HENRY E. NICHOLS, U. 8S. N., IN ALASKA AND BRITISH 
COLUMBIA, WITH A DESCRIPTION OF A NEW GENUS AND SPE- 
CIES, PRIONISTIUS MACELLUS. 
By TARLETON H. BEAN, M. D., 
Curalor of the Department of Fishes in the United States National Museum. 
The United States National Museum has again received from Captain 
Nichols two collections of forty-eight species of fishes, many of which are 
additions to the fauna of Alaska, while one has hitherto been unknown 
to ichthyologists. The Alaskan species are all from the southeastern 
part of the Territory. The following are especially interesting: Triglops 
pingelii, Gymnacanthus galeatus, Cottopsis gulosus, Sebastichthys nebulosus, 
Sebastichthys nigrocinctus, Micrometrus aggregatus, and Somniosus micro- 
cephalus, all of which are now for the first time definitely recorded from 
the region under discussion. 
These collections, like all others received from Captain Nichols, are 
in excellent condition, and it is a matter for congratulation that the 
same efficient officer has again visited a region so rich in interest which 
has been so little investigated by collectors. 
The quotations are from the notes accompanying the collection, and 
the numbers in marks of parenthesis are from the inventory of Captain 
Nichols. 
1. Gasterosteus cataphractus (Pall.) Tilesius. 
31959 (138). Near Duncan’s Bay, Brit. Col., June, 1882. 
2. Gasterosteus microcephalus Girard. 
31960 (187). Mountain Lake, near Ward’s Cove, Alaska, October, 1882. 
3. Pleuronectes stellatus Pallas. 
31983 (166). Port Simpson, Brit. Col., June, 1882. 
32012 (165). Port Simpson, Brit. Col., June 29, 1882. 
4. Citharichthys sordidus (Girard) Giinther. 
31991 (143). Johnston’s Straits, Brit. Col., June, 1882. 
31992 (147). Safety Cove, Brit. Col., June 21, 1882. 
No. 31992 has the following radial formula: D. 96; A. 79. 
5. Lepidopsetta bilineata (Ayres) Gill. 
31993 (154). Carter Bay, Brit. Col., June, 1882. 
A “flounder with white spots” and with the following radial formula: 
D. 77; A. 58. Teeth in upper jaw, 8+22; in lower jaw, 104 23. 
I have had some hesitation in referring this example to the species 
named above on account of certain peculiarities which must be subse- 
quently considered.
