PUGET SOUND CRUSTACEA. 263 



Doderlein, by whom they were collected in the same neighbor- 

 hood. The resemblance in both cases is so exceedingly close 

 that in spite of the imperfection of the Puget Sound specimen I 

 have no hesitation in adding P. pisiim to the list of species in- 

 habiting both sides of the North Pacific. It is recorded from 

 Japan by De Haan and Ortmann, and Mr. R. I. Pocock informs 

 me that there is a specimen in the British Museum from the 

 Philippine Islands.

The great number of closely allied species of Eiipagiinis oc- 

 curring in the region under consideration, and the imperfect 

 manner in which many of them have as yet been described, ren- 

 der the determination of the species a matter of difficulty in the 

 absence of named specimens for comparison. In this respect I 

 have derived great assistance from a valuable collection of ma- 

 rine invertebrates recently presented to the museum of Univer- 

 sity College by the Smithsonian Institution. In one or two of 

 the cases where this help was not available I have marked with 

 a query the names of species whose identification did not appear 

 to be beyond doubt. The largest and commonest species of 

 Eiipagiinis in Puget Sound, at first referred to as E. alaskensis 

 Benedict in Messrs. Harrington and Griffin's paper on the Inver- 

 tebrates of Puget Sound (Trans. N. Y. Acad. Sci., 1897, 159) 

 is apparently, as mentioned in i\Ir. Harrington's paper on com- 

 mensal nereids (ibid., p. 214), the E. annatus of Dana, which, 

 however, Stimpson has identified with the earlier E. ocJiotcnsisoi 

 Brandt (Stimpson, Proc. Acad. Nat. Sci. Phil., 1858, p. 236).
