150 VERRILL 



nodosa, not more than one-fourth its diameter. The upper and 

 lower marginals are wide apart ; the upper row is mostly single ; the 

 lower, mostly double ; the peractinal and the first subactinal row are 

 double; the imperfect synactinal row is single so that there are 

 about eight pretty regular and even ventral rows proximally. All 

 these spines and the adambulacrals are shaped as in the specimens 

 already described. 



Rather large, acute-ovate, dermal major pedicellariae are numerous 

 between the actinal and marginal rows, and large clusters of smaller 

 ones are abundant on the adambulacral spines. Papulae are exceed- 

 ingly numerous in large groups on the dorsal and lateral areas. 



The Asterias epichlora of M. de Loriol (non Brandt, op. cit, 

 1897) is doubtless identical with this species, and is not the true 

 epichlora of Brandt, which was evidently the common small greenish 

 Sitka species, and probably identical with A. saanichensis De Loriol 

 (op. cit., p. 23, pi. n, figs. 3-3^ 4, 5). This has been discussed under 

 A. epichlora. 



The differences that he found, in comparison with Stimpson's 

 description of troschelii, are variable characters in this species, as my 

 descriptions above will show. Some of the specimens studied by me 

 agree well with the one figured by M. de Loriol and came from the 

 same district. 



The geographical range of this species is extensive. I have 

 studied specimens from Mendocino, California, and Yakutat, Alaska. 

 It was taken by the Harriman Expedition on the Alaskan coast, at 

 Sitka, Wrangel, Orca, and Yakutat. Mr. J. F. Whiteaves, of the 

 Canadian Geological Survey, sent me specimens from the Straits 

 of Georgia, Malaspina Inlet, Discovery Passage, and Queen Char- 

 lotte Islands. Dr. C. F. Newcombe sent many specimens from Vic- 

 toria and Esquimault Harbor, some of large size. I have also 

 examined specimens from Puget Sound (Kincaid) and several other 

 localities. Departure Bay, British Columbia (H. J. Young, Canadian 

 Geological Survey, 1908), many large and small; Gulf of Georgia 

 (A. Agassiz, Mus. Comp. Zool.), a good series. 



EVASTERIAS TROSCHELII Var. RUDIS Verrill, nov. 



The three large specimens (h, i, /) about equal in size and form, 

 from British Columbia, appear to belong to this species, though they 

 have larger and swollen rays, and much coarser dorsal spines. One 

 of these has the radii 36 mm. and 252 mm. ; ratio, 1 : 7. The 

 specimens are flattened in drying, the dorsal skeleton being weak, 

 and this makes the rays appear broader.
