and contracted waist give the impression of a budding of the upper half of the specimen 

 from the lower. 



The colour is pale brown in spirit, and is due apparently to the abundance of 

 masses of cellules spheruleuses ; the specimens described by Topsent are grayish or 

 whitish. 



The ' Discovery ' specimens have, in parts, a hispid rather than a conulose surface, 

 the spicules standing above the level dermal membrane like sticks out of water ; but 

 in other places the surface is finely conulose. The oxeas are 642 x 18 n, those of the 

 'Belgica' being 630 x 18-20/ot. By deep staining of a portion of macerated skeletal 

 network a small amount of spongin becomes discernible at the nodes. The flagellated 

 chambers, 55 x 40ft, though rather large, are smaller than those of Topseut's specimens, 

 in which they are of unusual size, viz. 70 x 50 p. The second specimen is merely a 

 shapeless fragment. 



Dredged near Winter Quarters, off Hut Point, 25 fms. ; No. 12 hole, 25-30 fms. 

 The ' Belgica ' Expedition obtained several small specimens frortl 450 metres, in 

 Lat. 71 19' S., Long. 87 37' W.
