second and following segments with expanded ends and rounded in 

 section becoming after the fifth flattened laterally and much broader 

 in lateral view. 



Radials even with the edge of the centrodorsal in the median line, 

 but extending well up into the interradial angles and entirely separat- 

 ing the bases of the IBrj ; IBrj oblong or slightly trapezoidal, twice as 

 broad as long, widely separated laterally; IBr2 pentagonal, about as 

 broad as long, the lateral edges slightly shorter than those of the 

 IBrj and making with them a broadly obtuse angle. 



Ten arms about 55 mm. long; first brachial nearly oblong, about 

 twice as broad as long externally, interiorly in contact basally ; second 

 brachial about the same size but longer externally and shorter 

 internally; third and fourth brachials (syzygial pair) about as long 

 as broad; next two brachials approximately oblong, half again as 

 long as broad, the following becoming obliquely wedge-shaped, some- 

 what longer than broad, and gradually increasing in length distally, 

 the terminal brachials being twice as long as broad. The division 

 series have slightly prominent and finely spinous distal ends; after 

 the sixth the brachials develop strongly overlapping and very spinous 

 distal edges. 



Pi 10 mm. long with about thirty-nine segments, those after the 

 fourth being about as long as broad; the long terminal comb con- 

 sists of about twenty-five long curved teeth set closely together; Pj 

 6 mm. long, with a similar comb; P3 6 mm. long, with a comb consist- 

 ing of eighteen teeth; P^ very slender, 6 mm. long, with a comb of 

 twenty-one teeth, occupying rather more than its distal half; P5 very 

 slender and delicate, 4 mm. long, without a comb; following pinnules 

 gradually increasing in length, the distal pinnules, which are very 

 slender with greatly elongated segments, being 6 mm. long. 



The color is yellowish brown. ''

COMASTER (?) SCITULUS, new species. 



Centrodorsal thin discoidal, the dorsal pole flat, 1.5 mm. in diameter. 



Cirri XIX, 10-12, 5 mm. to 6 mm. long; first segment short, second 

 somewhat longer than the diameter of its expanded ends, third two 

 to two and one-half times as long as its expanded ends, fourth the 

 longest, about four times as long as the diameter of its proximal 

 end, a transition segment; following segments becoming very rapidly 

 shorter, and at the same time becoming laterally compressed and 

 increasing in lateral diameter, the penultimate segment being twice 

 as broad as long; fourth and following with thickened distal dorsal 

 edges and small sharp subterminal dorsal tubercles, which become : 

 central on the antepenultimate; opposing spine prominent but , 

 small, terminal, erect, or nearly erect, in height equal to about one-
