Type Locality.—Off Pribilof Islands, Bering Sea, 51 fathoms (‘‘ Albatross’’ 
station 3441). 
Distribution—Bering Sea to San Diego, California, 9 to 309 fathoms. 
Remarks.—The rostrum in normal individuals does not extend beyond the 
eyes; in many cases, however, it is evident that the rostrum has been broken off 
or injured and later renewed, the new rostrum having a narrow, elongated, and 
ascending tip, exceeding the eyes but of variable length. In other respects these 
abnormal forms do not differ from the types (Rathbun). 
Biological Survey of San Francisco Bay.—Crago communis was 
taken only at the most distant as well as the deepest of the outside 
stations, D 5788; twenty-five specimens in 60 to 68 fathoms; tempera- 
ture 9.3° to 11.3° C; salinity 34.0 to 34.2. Crago resima also was 
recorded from this station only; both C. alaskensis elongata and 
C. spinosissima were also taken here.

Characters.—The first five abdominal segments are smooth, the first and second 
segments have a thickened band along the posterior margin, in front of which 
there is a slight transverse depression; the fifth segment has an obscure median 
carina, with a short depression on either side at the anterior end; the sixth segment 
has two prominent carinae and a corresponding median depression; the telson has 
a slight median suleus. Eyes of moderate size. Second segment of antennular 
peduncle three times as long as the third. Rostrum long, narrow, pointed, 
advanced beyond the eyes, ascending at an angle of about forty-five degrees, 
slightly curved, and prolonged downward in a thin, compressed plate, which appears 
spatulate in a side view. The development of this plate is dependent on age; 
specimens 20 mm. long show no evidence of it. Hands shorter than in C. com- 
munis, about three times as long as wide, anterior margin also more longitudinal 
than in C. communis. Antennal scale about four-fifths the length of the carapace 
exclusive of the rostrum, spine exceeding blade.
