lar than in Koehler's type, but the specimen is larger, which may ac- 

 count for the difference. j» 



Numerous papulae are guarded by simple pedicellariae consisting 

 of 2 to 4 sharp spinelets, which meet at a common point and resemble 

 somewhat the fasciculate pedicellariae of Pectinaster. Similar 

 pedicellariae are common in Asierr/iopsis pedicellaris. 



The inferomarginal plates are larger than the others, longer than 

 wide, and define the ambitus. I am in considerable doubt as to 

 whether this specimen, which is regenerating 4 rays is not really a 

 6-rayed N. hrevis Perrier. 



The smaller specimen has perfectly regular abactinal plates. 



Type-locality. — Cochin China (Cape St. Jacques). 



Distribution. — Known only from the type-locality, from off Leyte 

 (vicinity Surigao Strait), 57 fathoms, shells, and from near Jolo. 



Specimens examined. — Station 5478, off Tacbuc Point, Leyte 

 (vicinity of Surigao Strait), 57 fathoms, shells. 



Marongas Island, north of Jolo, from a coral head, small specimen.

Diagnosis. — Rays 5. R = 16 mm., r = S.5 mm.. R = slightly less 

 than 2 r. Proportions and form variable; a four-rayed specimen 

 has the following dimensions: R = 17.5 mm., r=13 mm.,; in the 

 latter the margin of ray curves outward and has a broad leaflike 

 contour. Species characterized by presence along radial line of a 

 zigzag series of 7 to 11 wartlike conspicuous protuberances composed 

 of 4 upright spinulate plates guarding a large papular pore; other 

 abactinal plates with divaricate tuft of 8 to 12 very delicate spine- 

 lets; actinal intermediate area with spaced combs of 3 to 5 delicate 

 sharp spinelets; furrow spinelets 5, webbed, the adoral set back 

 slightly from margin; subambulacral spinelets 1 or 2, near adoral 

 margin of plate. 



Desci^iption. — Body very thin and raised only along the radial 

 lines, where there are 7 to 11 large papular pores forming a zigzag 

 series and each guarded by 4 plates, the edges of which are raised 

 so as to form a little mound or wartlike protuberance. The free 

 edges of the plates, bordering the relatively large pore, are semicir- 

 cular and the free surface of the plate is nearly perpendicular. These 

 plates are covered with numerous short, terete, delicate, blunt spine-
