unequal number, then one more in the non-prominent combs, instead 

 of one less, as in multipes); adambulacral spines longer. R=95 mm.; 

 r=60 mm. (measured to edge of actinostomial membrane); R=1.5r; 

 r=50 mm., measured to edge of paxillar area; breadth of paxillar area 

 at interradias, 50 to 57 mm. (=60% or less of R, while in multipes it 

 equals 80%, or more, of R. 



Type.— Cat. No. 37,016 U. S. N. M. 



Type-locality.— St&iion 5656, Gulf of Boni, Celebes (3° IT W S., 120°

Hymenaster rhodopeplus new species. 



Diagnosis. — Closely resembling H. nobilis Sladen, but difiering in hav- 

 ing 7 instead of 6 rows of paxillae to each ray, in having a stouter and 

 longer adambulacral spine (much longer than aperture papilla), and in 

 having 2 acicular suboral spines to each plate (instead of 1, resembling 

 an aperture papilla). Marginal contour pentagonal; R=82mm.; r=55 

 mm.; breadth of paxillar area at base, 35 mm.; distance from center of 

 disk to margin of paxillar area on interradial line, 30 to 32 mm. 



Type.— Cat. No. 37,017 U. S. N. M. 



Type-locality. —Station 5606, Gulf of Tomini, Celebes (0° 16'' 28^^ N., 

 121° 33^ 30'^ E.), 834 fathoms, green mud. 



Hymenaster bartschi new species. 



Diagnosis. — Very similar to H. pullatus, but differing ,in having the 

 paxillar areas of the 5 rays separated interradially nearly to the oscular 

 valves, and in having numerous spiracula in the supradorsal membrane, 

 there being a series of band-like spiracular areas along either side of the 

 paxillar areas extending toward the interradial line. General contour 

 originally probably nearly pentagonal, produced at the corners into 

 attenuate tips. R— about 70 mm. Supradorsal membrane very thin and 

 transparent between the numerous, conspicuous, criss-crossing muscle 

 bands. Pseudopaxillae in 7 rows, the median and adradial rudimentary, 

 with 1 to 3 tiny spinelets ; the 2 lateral series with 3 or 4 spinelets to each 

 paxilla. Furrow spinelets 3, flattened at the base and tapering to a 

 point, the adoral slightly the longest (1.5 to 1.75 mm.). Actinolateral 

 membrane broad, rather thin, deep brown in color ; twelfth to seven- 

 teenth actinolateral spines the longest. 



Type.— Cat. No. 37,018 U. S. N. M. 



Type-locality.— Station 5428, Sulu Sea, off eastern Palawan (9° 13^ N., 

 118° 51^ 15'^ E.), 1105 fathoms, green mud; bottom temperature, 49.7^ 

 Fahr. 



Named for Dr. Paul Bartsch of the U. S. National Museum. 



Zoroaster ophiactis new species. 



Diagrnosis.— Closely related to Zoroaster alfredi Alcock, from which it 

 differs in having longer rays, stouter, conical, carinal spines, relatively 

 smaller papular pedicellarise, ungrooved spinelets, less numerous adambu- 

 lacral pedicellarise, and in lacking, deep in the furrow, the 2 large bunches
