long; extensive intermarginal series of plates; adambulacral armature 

 consisting of a zigzag series of 6 or 7 long bristling spinelets decreasing 

 in size from furrow edge, and in addition 1 spinelet deep in furrow; 

 actinal intermediate plates extending only about half length of ray. 

 E, 47 mm; r 9 mm; R 5,2 to 4,5 r; rays unequal. 



Queen Charlotte Sound, off Ft. Rupert Vancouver Island, 107 

 to 68 fathoms; bottom, soft green mud. 



This species is notable for the prominent fasciculate spinulation 

 and the conspicuous adambulacral spinelets. The spinelets are much 

 longer and sharper than in smiguinolenta, the groups much more spaced 

 on account of the open character of the skeleton, and the adambulacral 

 spinelets much longer. 



Henricia ciarla new species. 



Rays long, very slender, and flexible, tapering from a narrow base 

 to an attenuate, blunt, extremity ; rays subcylindrical ; abactinal surface 

 depressed; interbrachial angles abrupt, about 90", not rounded; disk 

 very small; plates delicate, forming a sinuous meshwork enclosing 

 smaller, lower, secondary plates (also more or less joined in a close mesh) 

 between which emerge single papulae; adambulacral plates with 35 to 

 40 spinelets (on proximal part of ray) and in the furrow 2 spinelets, 

 except on the proximal 6 or 8 plates where there are 3 to 5 in a vertical 

 series. R 54 mm; r 7 mm; R 7,7 r; breadth of ray at base, 7 to 9 mm. 



Off Santa Cruz Islaiid Cal., 475 to 510 fathoms. Bottom, black 

 mud.

Solasteridae. 



Solaster exiguus new species. 



Rays 7. R 25 mm: r 8 mm; R 3 r. Similar in general appearance 

 to S. paxillatus Sladen, but disk smaller, paxillae smaller, inferomarginal 

 plates more widely spaced and much narrower, with fewer longer 

 spinules, actinal interradial areas smaller (despite the fewer rays): 

 furrow spinelets 2 or 1, long; actinal adambulacral spinelets 3 to 5, the 

 comb slightly curved aborad at inner end, and middle spinelets longest. 

 Mouth plates small with 6 to 8 marginal and 2 to 5 superoral spinelets, 

 the former webbed basally, and the inner 2 or 3 enlarged into teeth. 



Off Anacapa Island, California, 603 fathoms. Bottom, green mud. 



The paxillae of this species are not so small as those of S. endeca or 

 S. borealis. They are spaced farther than their width, and are arranged 

 in definite longitudinal and oblique transverse rows. Each paxilla has 5
