Ëchinoclathria Cart. 

 E. sp. 

 From Angmagsalik, depth 140 fathoms, the Amdrup-expedi- 

 tion 1900 has brought home a large, flabelliform species which 

 present the characteristic honeycombed structure. It appears 

 to be undescribed. 



Plocamia 0. Schmidt. 

 Two species of this genus have been collected at Cape 

 Tobin, depth 67 fathoms, and at Angmagsalik, depth 140 fathoms 

 (The Amdrup-expedition 1900). Further we have it from the East- 

 coast, without particular locality (The Ryder-expedition 1891 — 92).

We have two specimens of this species, both of flabelli- 

 form shape, but somewhat irregular; the skeleton has rather 

 strong fibres, composed in the common way of long and strong 

 "vermicular" spicules. The largest specimen has a height of 

 110 mm.

We have of this sponge two pieces, one being a lower and 



the other an upper part, both parts certainly belonging to one 



individual; below there is a short and robust stalk, to which 



some bottom material still adheres; from the stalk the sponge 



rises into a funnel-shaped part, but this shape disappears a little 



way above the stalk, and only one side of the funnel continues
