spina. The ran' as a whole reaches its best development along the Aleutian chain, 

 the type locality of mvMspina. 



Typical examples are readily distinguished from leviuscula by their delicate and 

 more numerous, rather hyaline spinelets, ending in several delicate thorns. Varia- 

 tions with larger or smaller abactinal plates and slender to stout rays occur. I do 

 not think it is possible to distinguish a northern multispina from a southern spiculifera 

 and have accordingly united the two. 



HENRICIA ASPERA Fisher, pt. 1, p. 293. 



Bering Sea (Bering Island, Pribilofs, Aleutian Islands) south along the coast to 

 the Santa Barbara Channel, Calif.; 26 to 313 fathoms; mud, sand, pebbles, shells, 

 rocks. 



HENRICIA ASPERA forma ANNECTENS Fisher. 



Henricia leviuscula annectens Fisher, 1911, p. 291, pi. 70, fig. 2d; pi. 71, figs. 1, 3. 



ll< nricia leviuscula var. annectens Verrill, 1914, p. 224. 



Aleutian Islands to Santa Barbara Channel, Calif., 21 to 135 fathoms; rocks, 

 shells, sand, mud. 



This form in most respects is intermediate between aspera and leviuscula but 

 resembles aspera more than leviuscula. Specimens referable to this forma have been 

 taken also at station 3220, near Unalaska, 34 fathoms; and station 4784, near Attu, 

 Aleutian Islands, 135 fathoms. The range is probably coextensive with that of 

 aspera.
