I have little to add to the very full accounts of the many varieties of Deltocyathus itcdicus contained in the 

 memoirs cited. ... It is very remarkable that none of the specimens obtained by us were attached, and that 

 only one shows any trace of ever liaving been attached. This one specimen [from Station 285, South Pacific, 2375 

 fathoms], liowever, is large, and though somewliat imperfect, has a most distinct pedicle and scar of attacliment, and 

 evidently remained fixed up to a period of full maturity. — (Moseley, Zool. Chall. Exp., part 7, pp. 145, 146.) 



- Solenosiiiilia variabilis is a very widely-spread and characteristic deep-sea form, and varies exceedingly. JIany 

 specimens dredged by us were dead, old, and much broken, but always recognisable by the peculiar mode of branching 

 and the texture of the crenenchym. — (Moseley, Zool. Chall. Exp., part 7, p. 181.) 



^ Of the stalked Crinoids Rhizocrinus has the farthest northern range (08° N.), but it has not been met with more 

 than once (Station 122), or possibly twice (Station 323), south of the equator, and is limited to the Atlantic and Carib- 

 bean Ocean. — (Carpenter, Zool. Chall. Exp., part 32, p. 136.) 



' The form of the calyx in this species [Bhi::ocrinus lofotcnsis] varies veiy considerably ; for it is nearly hemi- 

 spherical in some specimens and much elongated in others. These last have the best developed arms ; and to some 

 extent, therefore, the forms with a low and wide cup must be regarded as premature. But differences of development 

 will not entirely account for the variation, as the calyx of a young specimen found by Sars is distinctly higher (longer) 

 than liroad. — (Carpenter, Zool. Chall. Exp., part 32, p. 261.) 



^ Of Dytuster exilis and its two varieties, carinata and ijracitis, Sladen writes : — The variety carinata resembles the 

 type more nearly than the variety ijracilis does. The wide separation of the geographical positions of the type and its 

 two varieties is of the greatest interest, and bears evidence to the enormous range of the Ihjtastcr exilis form, and of tlie 

 comparatively small amount of variation exhibited by this type in what may well be spoken of as extreme limits of 

 position. The type comes from the Pacific, off the western coast of South America, the nearly allied variety carinuUi 

 from the North Atlantic, off the eastern coast of the United States of America, whilst the more divergent variety — 

 if, indeed, it be not a distinct species — was dredged in the South Atlantic, westward of Tristan da Cuuha.— (Zon/. CIkiII.
