Iiu/ian Deep-sea A.steroulea. 103 



four large spiiielcts, each with a large pediceUaria and often 

 also a hunch of small ])cdicellarite 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 ])edicellaria;, twelve 

 to twenty in each bunch ; all the adambulacral ])lates are 

 covered with spinelets and small pedicel lariie on their narrow 

 actinal edge. 



Madreporiform plate large, with coarsish radial striations. 



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

 spines a little ])aler " {G. M. Giles). 



Bay of Bengal, 1300 to 1380 fathoms, Glohigerina-oovM. 



This large and very beautiful species is readily distinguished 

 by the extraordinary development of its pedicellaria3, espe- 

 cially by the two large ceespitose masses of these organs which 

 are borne on every alternate adambulacral ]jlate between the 

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

 more conspicuous than any of the spines except those on the 

 ])lates 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, sj). n. 



Rays 5. R=1G r. R = about 180 millim. in the 

 type specimen. 



Disk extremely small, not differentiated from the bases of 

 the rays, tumid j rays extremely long and finely t:i[)eriug, 

 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 

 e(jual 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 papuhe and 

 bear from one to three pediceUaria?, of which one is sometimes 

 slightly enlarged. 



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

 hexagonal plates coserial with the large jjrimary ratlial, 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, 

 the lowest row abutting on the adambulacrals ; tliese plates 

 also fall 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
