I now proceed to give descriptions of the new species represented 

 in the present Collection, and notes on others previously described. 



I. HOLOTHUEIOIDEA. 



It is remarkable that the collection of Holothurians should be 

 so very scanty; Mr. Bassett- Smith tells me that it always struck 

 him "as being a most remarkable thing that in the 100 odd 

 dredgings on the Macclesfield Bank and China Sea only two minute 

 specimens were obtained." 



n. CRINOIDEA. 

 Ettdioceinus GKANTiLATirs, sp. nov. (Plate XXIII.) 

 Like E. indivisus ^ in having the first two brachials united by 

 syzjgy and the first pinnule on the left side of the second brachial. 



^ As pointed out by Brock (Zeit. f. w. Zool. xlvii. p. 530), this species is 

 omitted by Mr. Lyman from his ' Challenger' Eeport; I doubt if research will 

 ever find another case of omission. It may be useful to add the original 

 reference ; it is Arch. f. Nat. xxxvi. (1870) p. 249.
