194 VERSILL 



Stout, enlarged distally, truncate, and mostly grooved or gouge- 

 shaped at the end. They are much crowded and stand mostly five or 

 six to a plate. 



The inferomarginals are similar in form, a little longer, and mostly 

 stand two or three to a plate, in oblique groups. There is a well 

 marked channel between these and the superomarginals, but no 

 intermarginal rows of spines. A similar regular channel separates 

 the inferomarginals from the adambulacrals. These channels are 

 both occupied by large papular areas, with clusters of small papulae, 

 and by rather large, acute major pedicellariae. 



The adambulacral spines stand mostly two and three to a plate, 

 alternately, every other plate bearing a rather long, tapered, furrow- 

 spine. Most of their other spines, on the actinal side, are stout, 

 enlarged distally, and grooved or gouge-shaped on the outer side. 



The minor pedicellariae are few and very small. They are entirely 

 lacking on most of the dorsal spines, and very few occur on the 

 marginal spines. 



The major pedicellariae are frequent both on the actinal and on the 

 lateral areas, but not abundant. They are few and scattered on the 

 dorsal surface. The larger are compressed, acute-lanceolate, some 

 more acute than others ; the smaller ones are short-lanceolate or 

 ovate. 



The jaws are elongated and rather compressed. The two upper 

 apical spines are stout and bear small clusters of acute major pedi- 

 cellariae; the lower ones are much smaller, bent, acute. There are 

 two spaced pairs of stout epiorals. 



The type is from St. Michael, Alaska (L. M. Turner, 1874-76, 

 No. 3821, U. S. Nat. Mus.).

Rays five, rather short, wide at base, depressed, tapering rapidly, 

 rather acute, bordered by a fringe of superomarginal spines. Radii, 



20 mm. and 58 mm. ; ratio, about 1:3; breadth of rays at base, 



21 mm. 



The dorsal spines are well spaced, rather scattered, but on the 

 sides of the rays forming pretty evident radial rows ; median row 

 distinct but not prominent. They are short, stout, about twice as
