Indian Deep-sea Asteroidea. 103 



four large spinelets, each with a large pedicellaria and often 

 also a bunch of small pedicellarue attached by ligament to its 

 base, and which, deep in the roof of the furrow, bifurcates to 

 give origin to a pair of large bunches of pedicellaria3, twelve 

 to twenty in each bunch ; all the adambuh^cral plates are 

 covered with spinelets and small pediceliarite on their narrow 

 actinal edge. 



Madreporiform plate large, with coarsish radial striations. 



Colour in the fresh state " deep salmon-colour throughout, 

 spines a little paler" {G. M. GiJes). 



Bay of Bengal, 1300 to 1380 fathoms, Glohigerina-OOY^Q. 



This large and very beautiful species is readily distinguished 

 by the extraordinary development of its pedicellarite, espe- 

 cially by the two large casspitose masses of these organs which 

 are borne on every alternate adambulacral jjlate between tlie 

 bases of the tube-feet, and by the large pedicelhiriaj (much 

 more conspicuous than any of the spines except those on the 

 plates of the two most actinal rows) arranged in regular 

 longitudinal and transverse parallel series along the rays. 



It was named by Messrs. Wood-Mason and Giles after 

 Commander Alfred Carpenter, R.N. 



38. Zoroaster Barathri^ sp. n. 



Kays 5. li=16r. R = about 180 millim. in tlie 

 type specimen. 



Disk extremely small, not differentiated from the bases of 

 the rays, tumid ; rays extremely long and finely tapering, 

 semicylindrical. 



Abactinal surface of disk with large, close-set, subhexagonal 

 primary radials and interradials surrounding an apical mass 

 formed of a dorso-central and radial underbasal plates, all of 

 equal size; all the plates are very closely covered with 

 capillary spines, and the small depressions which intervene 

 between the plates are perforated for one or two papuUe and 

 bear from one to three pedicellaria, of wliich one is sometimes 

 slightly enharged. 



The rays have a longitudinal mid-radial row of large tumid 

 hexagonal plates coserial with the large primary radial, and 

 on each side of it six (in the interbrachia seven, at the end of 

 the rays five) parallel rows of smaller plates, very close-set, 

 tlie lowest row abutting on the adambuhicrals ; tliese plates 

 also tail into close-set transversely parallel series, and all are 

 densely covered with capillary spines that become gradually 

 longer and more slender in each successive row from the
