142 VERRILL 



mostly a little clavate and flattened. The inner one is slender, 

 tapered, and often bears a small cluster of acute pedicellariae. 

 Adoral spines are similar but longer. No large dermal major pedi- 

 cellariae were found.

The type of this is a very distinct form. The equal, crowded, 

 capitate dorsal spines, arranged in areolations and evident longi- 

 tudinal bands, are notable; the superomarginals, three or four to a 

 plate, are also peculiar. The open reticulation of the ossicles is per- 

 haps more important. 



LEPTASTERIAS EPICHLORA PUGETANA Verrill, subsp. nov. 



The type specimen from Puget Sound is very peculiar in appear- 

 ance. The dorsal spines are nearly equal, numerous, crowded, and 

 capitate. They are somewhat areolate, forming circles around the 

 very evident papular areas. The median radial bands are evident, 

 but not prominent. Both the marginal rows are double, with rather 

 stout obtuse spines. The peractinal row has similar short spines, 

 close to the adambulacrals. The skeletal ossicles are stout and 

 rather closely articulated. Large, erect, serrate major pedicellariae 

 are numerous on the sides of the rays. Radii, 10 mm. and 35 mm. ; 

 ratio, i : 3.5.

LEPTASTERIAS ( ?) DISPAR Verrill, sp. nov. 

 Plate xvi, figure 7. 



Disk moderately large, rays six, angular, depressed, rather short, 

 tapered rapidly. Radii, 8 mm. and 32 mm. ; ratio, i : 4. Dorsal 

 spines very unequal in size and form. The larger ones are stout 

 and strongly capitate, with large, round, finely spinulose heads ; they 

 form conspicuous but irregular median radial rows, two or three 

 often standing on one plate, and also small groups on the disk. 

 Smaller spines of various sizes, partly capitate like the larger ones, 

 and partly slender and tapered or slightly clavate, are scattered over 

 the surface, but mostly in imperfect submedian rows; larger speci- 

 mens might have them in regular rows. 



Marginal spines are similar to the larger dorsals, but not so stout. 

 They form pretty regular rows, one to a plate proximally, but mostly 

 two to a plate distally. Ventral spines are decidedly longer and
