eac'li H central tuft of capillary spinelets, the tufts and their 

 constituent .s{)Inelets being enlarged in a mid-radial row. 

 The papuUii are In four rows, two on each side of the mid- 

 radial line, the inner row on each side extending from the 

 centre of the disk to the tip of the raj, and the outer extending 

 continuously only about halfway along the ray, and thence 

 onward in a broken series. In young specimens there are 

 only two rows of papulic, one on each side of the mid-radial 

 line. 



The papular pores, like the papuUu themselves, are of two 

 kinds ; all are encircled by a close palisade of spinelets, but 

 from three to six of the pores of the inner two rows are much 

 enlarged, to give exit each to a singularly long papula, and 

 these are encircled by spinelets of superior length ; the small 

 pores give exit each to a small short papula. 



The marginal plates, which lie in alternation with the 

 oblique rows of abactitial plates, are minute, and each is 

 edgetl with a tuft of spinelets and each has a very minute 

 scale-like platelet at Its base. 



The adambulacral plates have each a palmate furrow-series 

 of six spinelets and actinally an oblique or curved series of 

 three or four ca))illary spinelets; the mouth-])lates have a 

 furrow-series of eight or nine spinelets which increase in size 

 adorally and a suture-series of live or six capillary s])inelets. 



The actinal plates are in regular longitudinal and oblique 

 rows, and diminish in size from the actinostome to the 

 margin ; each plate carries a radiating marginal series of 

 capillary spinelets, four in a series near the actinostome, three 

 elsewhere.

36. Choitaster^ sp. 



\\\ our collection there is a small broken specimen of an 

 imdoubted Cha4aster which I do not at present venture to 

 describe. In appearance it corresponds with the figure of 

 Chcetaster miinitus^ Moblus (' Neue Seesterne des Hamburger 

 und Kleler Museums,' pi. I. figs. 1 and 2), and, so far as the 

 description [op. cit. p. o) of that species goes (a description 

 which, however, Is certainly incomplete). It corresponds with 

 it exactly. With Professor Moblus's form I should have 

 identified our species, had not Choitaster munituSj Mobius,
