or trifid; a large sessile bivalved pedicellaria occupying furrow margin of first plate, extending whole 

 length of plate; a similar pedicellaria occurring frequently on other plates of the series; on actinal 

 surface of each plate a robust spine just behind the furrow spines, which it greatly resembles, though 

 a trifle shorter; tin- spine either bluntly tipped, compressed, or curiously wrinkled, and reduced I" 

 a small conical tubercle, a mere specialization of one of the granules, on those plates in which a 

 pedicellaria replaces the furrow series; general surface of plate covered with irregular plate-like 

 granules similar to those of the actinal intermediate plates. 



Month plates fairly large; furrow spines 3, flattened, the inner flaring and hatchet-like though 

 irregular; an odd spine at inner angle of the combined plates; one much smaller spine on actinal 

 surface adjacent to outer furrow spine; surface of plate covered with 1' longitudinal (interradial ) rows 

 of flattened plate-like granules which diverge atid partially surround the actinal spine, being much 

 smaller toward the inner angle; these granules quadrate or pentagonal, and their surface sunken a 

 trifle, then raised in a small low boss in the center. 



Actinal interradial areas large; a single row of intermediate plates extending very nearly to tip; a 

 second series I the length of ray; a third very nearly as far; a fourth nearly half, and so on; plates adja- 

 cent to adambulacrals largest, elongated transversely, ami more regular than the others, though far 

 from regular themselves; most of them hearing a long bivalved sessile pedicellaria (4 mm.) not more 

 than 0.5 mm. high, placed transversely or obliquely transversely, forming a very conspicuous series 

 on either side of the adambulacral series and extending about half the length of ray; Hat, oblong, or 

 irregular granules surrounding them, the whole somewhat convex in appearance; a number of the 

 granules with a subcorneal prominence in the center, the other intermediate plates bearing a centra) 

 conical tubercle, surrounded by several low conical granules which grade into the flatter, plate-like 

 granules toward the periphery of the plate, these granules resembling those of the abactinal surface in 

 shape but not free on tin' edges. 



Madreporic body fairly large, somewhat convex, irregular in outline, situated nearer center than 

 midway to margin; striations deep, irregularly interrupted; anal opening surrounded by a cluster of 

 bead-like granules. 



Color in life, scarlet vermilion.

Lophaster furcilliger, new species. 



Rays 5. R = 70mm.; r = 16mm.; R = 4.38r. Breadth of ray at base, 18 mm. 



Rays rather long, tapering from a narrow base very gradually to pointed extremity; disk rather 

 small; abactinal surface convex on rays and disk; interbrachial angles narrow and acute; ambulacra] 

 furrow very wide and open. 



Abactinal surface beset with paxilke which have rather' long I L'-M mm.) slender pedicels, with a 

 capitate summit beset with numerous 1 I'll or even more) long, delicate, glassy spiculiform spinelets, 

 flattened, flaring and bifurcate at the tip, arranged in a glomerular tuft on the subglobose tip of the 

 pedicel; these spinelets about 1 to 1.1' mm. in length and radiating in all directions; paxilke largest on 

 disk, decreasing in size toward end of ray; papuke numerous. 



Supermarginal paxilke well developed ami larger than abactinal except on outer 3 of ray, where 

 the two are about equal; well spaced and with stouter and longer (3.5 mm. | pedicels than tin' abac- 

 tinal paxilke, the spinelets being usually trifurcate. lnferoinarginal paxilke still stouter, about T.\ in 

 number from median interradial line to extremity of ray. 



Adambulacral plates short and broad, with wide intervals between successive plates, the suture 

 being wider than the length of exposed surface of plate; furrow series consisting of 4 spinelets at 

 base of ray, which are soon reduced to 3, their to 2 beyond middle of ray, and finally to 1; these 

 spinelets rather long, delicate, skin-covered and united lor J or i their length by a web; when there 

 are 1. they are graduated in length toward theadoral, which is shortest; when there are 3, the middle
