E. CURVISTELLATA. 



2ia 



measuring 7-3-100 ,"• — uii an average 90 /< — in diameter (against 



50-70 ft of K owenl). The rays, both 

 principal and terminal, are somewhat 

 stouter. (Coaipare the annexed wood- 

 cuts with PI. VI, figs, o & G). More- 

 over, the smooth and finely attenuated 

 terminals, of which there are 3 or 4 

 (sometimes '">) to each short principal, are 

 near their free ends always more or less 

 distinctly curved, frequently in an almost 

 hook-like manner. For the rest of their 

 length, the terminals are nearly straight. 

 The bending takes place apparently 

 without any definite rule as to its direc- 

 tion. The termiuals belonging to the 

 same principal are sometimes bent all 



alike outwards, i. e., away from the axis of the principal. At 



other times they may be bent some outwards and some inwards, 



or in any intermediate direction.

Finally, let it be mentioned that the specimen contained in 

 its gastral cavity a pair of Sjiongtcola rcmisia, known also to in- 

 habit E. asperf/Uhuii, E. marshaUi and E. oiceni. Besides, I 

 have a specimen of Hyaloncma sieholdi harboring a pair of the 

 same Crustacea. The identity of the inmate may be taken as 

 suggestive of similar bathymetrical aud other conditions under 

 which the above-mentioned Hexactiuellid species live.
