SHALLOW-WATER STARFISHES 223 



I have seen no specimens of it from much north of the Aleutian 

 Islands, which are usually considered its northern limit. 



I have studied specimens from Bering Sea, which are, perhaps, of 

 the same variety as some of those recorded by Fisher from the same 

 region. My arctic form, however, appears to be a variety of H. san- 

 guinolenta, which is much like .the Atlantic variety pectinata. 



Professor Fisher gives the range of his multispina as from Oregon 

 to Bering Strait and Kuril Islands, and from low tide to 238 fathoms. 



This species or subspecies appears to be closely related to, and may 

 be the same as Henricia densispina (Sladen, 1878, p. 432, pi. vm, 

 figs. 5-9, as Cribrella), from the Straits of Korea, 40 fathoms. 



The latter also has two spines on the furrow margin and several 

 graded pairs back of them, with very numerous, crowded, rough, 

 thorny spinules on the close marginal and dorsal plates ; papular areas 

 small, mostly with isolated or few papulae. 



The Japanese species, figured, but not described, by Ives (op. cit., 

 1891, p. 212, pi. ix, figs. 1-4) as Cribrella sanguinolenta, is not that 

 species. It belongs to the section of the genus having a pair of spines 

 on the furrow margin, but it has fewer on the actinal surface. Its 

 dorsal ossicles are narrow, very openly reticulated, bearing spinules 

 in about two rows, and surrounding unusually wide papular areas. It 

 may be called HENRICIA JAPONIC A. 



HENRICIA LEVIUSCULA, var. DYSCRITA Fisher 



(as a subspecies). 



Plate xii, figure 6. 



Henricia leviuscula dyscrita FISHER, op. cit., 191 ib, p. 289, pi. LXXIV, figs. 

 1-5- 



Form and general appearance intermediate between leviuscula and 

 multispina; abactinal ossicles smaller than in the latter, with similar, 

 but fewer, delicate spinules and usually larger papular areas, larger 

 than the pseudopaxillae. The abactinal spinules end in several deli- 

 cate points. 



Adambulacral plates carry about fifteen spinules ; two intra-fur- 

 row spinules occur, if at all, only near the tip of the ray. 



Dr. Fisher records this form from eighteen localities in 21 to 80 

 fathoms, from Monterey to Southern California. South of Monterey 

 " it predominates everywhere over leviuscula." 



Two specimens from Sitka (coll. Harriman Expedition) seem to 

 agree closely with this form in all respects. (See pi. xii, fig. 6.) 

 Others are from British Columbia.
