description of Stcherites dongatiis (31) are, besides that referred to, the 

 more slender form of the large styli, and the absence of a true 

 pedicel. In regard to the last point, several specimens of the 

 same species were collected during a subsequent cruise at a more 

 distamt and deeper position in the Channel. These all show the 

 typical slender pedicellate growth, characteristic of elongata, while the 

 spiculation of two specimens examined shows no appreciable difference 

 from the foregoing description, except that the numerical proportion 

 of tylote to simple styli in the dermal fasciculi is lower. 



The species has been recorded from the Bay of Biscay : one, 

 in 248 m. (Topsent, 38); one, in 180 m. (Topsent, in 10); Coast of 

 Eoussillon, two, in 94 m. (Topsent, in 10) ; Azores, eight, in 450 fath. 

 (Eidley and Dendy, 31).

At Position 46, one specimen, broken from attachment — possibly 

 Lcpralia ; forming an erect compact growth of 

 irregularly inosculating, more or less tubular 

 branches, the whole somewhat depressed laterally 

 and with some external resemblance to certain 

 broadly expanded forms of AlcijonicUum gelatino- 

 sum; with several oscula raised on low prominences 

 of 2-4 mm. in diameter. Height, 65 mm. Width, 

 62 mm. 

 „ 68, one broken specimen, on Zejyralia foliosa ; with 



massive basal portion, 50 x 40 mm, in extent, 

 tunnelled by tubular ramifications and sur- 

 mounted by at least one large tubular process, 

 60 mm. in height by 25 mm. in diameter, with 

 an osculum at summit, 9 mm. in diameter. 

 Depth, 47-52 fath. 



The texture of the first specimen is compact and rigid, and similar in 

 general appearance to Bowerbank's figures for the species ; that of the 

 second, except for a certain rigidity about the base, is quite the opposite. 

 In external characters the two specimens are quite distinct, but the 

 internal structure of both, including the form and dimensions of the 

 spicules, shows so little difference that there seems no justification for 

 separating them. The skeleton is composed of two distinct elements : —
