regular, massive lumps with much bottom material imbedded, 

 only one of the specimens has distinct papillae. The specimens 

 from Forsblad-Fjord are fragments, probably of the lower part 

 of the sponge, as they show no papillae; the latter specimens 

 have very large spicules, of a length up to 1'2 mm.

From Cape Dalton ^^/^ 1900, depth 9— 1Ï fathoms (The 



Amdrup-expedition 1900) we have a small fragment of a Beniera 



which in every respect seems to agree with Beniera folium, 



the spicules are of the same shape and likewise of a length 



of 0*19 — 0"21 mm, but the fragment is too small to allow a 



quite sure determination.

 As mentioned in "The Danish Ingolf-Exp." 1. c. we have 

 two small specimens from East-Greenland, 72° 40' lat. N., about 

 20° long. W., depth 100 fathoms (The Ryder-expedition 1891 

 — 92), but these have spicules, which are a little longer than 

 those of the original specimen, so that the identity is not sure. 

 Later on a specimen is brought home from Tasiusak, '^^/s 1902, 

 depth 30 — 50 fathoms (Kruuse); this specimen is quite agreeing 

 with that described by Levinsen; the spicules have a length 

 of 0'23 — 0'27mm, and a diameter of about 015 mm. The spe- 

 cimen has a length of 50 mm; it shows an osculum at the summit.
