DECAPODS IOI 
Walker says of this species that “the rostrum reaches a little beyond 
the end of the peduncle of the inner antennz,” but this may be an error, 
as in the figure the rostrum is represented not much longer than the eye. 
Dimensions.— Length of female with ova 30 mm. (Walker). Length 
of female with ova 16.2 mm., length of carapace and rostrum 5.2 mm., 
of rostrum 2.1 mm. 
Distribution.—Sitka, Alaska, 10 fathoms, June 15, one @ with ova 
(Harriman Expedition). Puget Sound, 1895, 3 specimens (T. Kincaid), 
Puget Sound (Walker). 
SPIRONTOCARIS TAYLORI (Stimpson).

Heptacarpus Taylori HOLMES, Occas. Papers Calif. Acad. Sci., VII, 199, pl. 
Ill, figs. 52, 53, 1900, and synonymy. 
Distribution.—San Francisco Bay, California, to Magdalena Bay, 
Lower California. Specimens in the National Museum from Monterey 
(D. S. Jordan, 1880, and J. O. Snyder, 1895), San Pedro (Adbatross), 
Point Loma (A/datross), San Diego (Rosa Smith). 
One of the three females collected by Dr. Jordan has an abnormal 
rostrum, longer and more slender than in typical specimens, still not 
reaching the cornea; in other respects the individual agrees with its 
associates.

Since this paper went to press, a Spzrontocaris from Pearson, Wash- 
ington, has been received, through R. W. Doane, which seems to be un- 
described. It has the coloration of S. Aicfa, a rostrum similar to that of 
S. paludicola, while the epipods are as in S. sétchensis,
