Our collections contain specimens from the following Localities: Albatross station -I2s."> (Chignik 

 Baj v 4268 (Afognak Bay), 4276, 4277, 4278, and 4279 all in Uitak Baj . and 3653 Bering Sea). The

from many stations in Bristol Hay. 



A female 2.5 inches long, from station 127'.). August ti. contained 105 nearly ripe eggs, measuring 

 about 18 to the inch. Of the 15 specimens from Alitak Bay, 2 are males which exhibit a markedly 



fuller development of the dorsal fins than the others. A small thread-worm was found in the abdominal 

 cavity of one specimen.
