DECAPODS 101 



Walker says of this species that " the rostrum reaches a little beyond 

 the end of the peduncle of the inner antennse," 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). 



Hippolyte taylori STIMPSON, Jour. Boston Soc. Nat. Hist., vi, 500, 1857. 

 Heptacarpus Taylori HOLMES, Occas. Papers Calif. Acad. Sci., VII, 199, pi. 

 Ill, figs. 52, 53, 1900, and synonymy. 



Distribution. Son. 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 (Albatross\ 

 Point Loma (Albatross], 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. 



SPIRONTOCARIS PICTA (Stimpson). 



Hippolyte picta STIMPSON, Ann. Lye. Nat. Hist. N. Y., x, 125, 1871. 

 Heptacarpus pictus HOLMES, Occas. Papers Calif. Acad. Sci., VII, 200, pi. ill, 

 figs. 54 and 55, 1900, and synonymy. 



Distribution. Monterey Bay to San Diego, California. Specimens are 

 in the National Museum from Monterey Bay (Albatross], Pacific Grove 

 (H. Heath, John C. Brown), Catalina Harbor (W. H. Ball), Lajolla 

 (Albatross], San Diego (various collectors). 



SPIRONTOCARIS PALUDICOLA (Holmes). 



Heptacarpus paludicola HOLMES, Occas. Papers Calif. Acad. Sci., VII, 201, 

 pi. in, figs. 56, 57, 1900. 



Distribution. Humboldt Bay (Holmes) to San Diego, California. 

 Specimens are in the National Museum from San Diego (Albatross], and 

 from either Monterey or Catalina Harbor (Dall). 



Since this paper went to press, a Spirontocaris from Pearson, Wash- 

 ington, has been received, through R. W. Doane, which seems to be un- 

 described. It has the coloration of S. picta, a rostrum similar to that of 

 S. paludicola, while the epipods are as in S. sitchensis.
