CRANGON ALASKENSIS ELONGATA Rathbun. 
Crangon alaskensis elongata RATHBUN, Proc. U. S. Nat. Mus., XxIv, 888, 
1902. 
The typical C. alaskensis described above passes by insensible grada- 
tions into a form occurring off the coast of California and Oregon, which 
differs from it as follows: The rostrum is longer and 
narrower. The outer flagellum of the antennules falls 
considerably short of the antennal scale. The scale is 
much longer than in the typical form, being equal to the A 
length of the carapace exclusive of the rostrum. The 
fourth segment of the abdomen shows signs of carination, ="

Dimensions.—Length of ovigerous female from tip of ae a al 
rostrum to tip of telson 55.7 mm.; length of carapace 13.5 mm.; length 
of antennal scale 11.6 mm. 
Type locality.— Off Santa Barbara, California, 29 fathoms, stations 2970, 
2971 (Albatross). 
Distribution.—This species occurs in abundance off the west coast of 
the United States. It has been taken by the A/sazross at thirty stations 
in 9-278 fathoms, off California, Oregon, Washington, and British Colum- 
bia, and in Strait of Fuca and Puget Sound. The southern limit is off 
Wilmington, California. It has also been collected in Monterey Harbor 
by Dr. W. H. Dall, and at Pacific Grove by Mr. J. O. Snyder. 
Variations.—The more northern of these specimens (those off the coast 
of Washington more especially) have the scale not quite so long as the 
types, but still equal to about four fifths the length of the carapace; the
