To this species I refer with some doubt three cylindrical, 

 tubular specimens without oscular fringe; the specimens are 

 not at all compressed; the largest specimen has a length of 

 about 12 mm, the diameter is up to 2 mm, the body wall is 

 very thin, only 0*25 mm. The surface is only slightly hispid. 

 My reason for determining the species as pennigera is the 

 shape of the dermal rhabds which is chiefly agreeing with the 

 figure by Haeckel.

Of this species there are six specimens in the collections; 

 they are all sack-shaped, cylindrical or compressed, and they 

 have all a single osculum; the osculum is not quite bare but 

 in some of the specimens provided with a short fringe. (Spe- 

 cimens with a fringed osculum are also mentioned by Fri- 

 ste dt: Vega-Exp. vetensk. lakttag. IV, 1887, 410). The spe- 

 cimens are not large, the largest one has a height of 26 mm. 

 All specimens have the characteristic network, formed of strings 

 of small rhabds, in the gastral cavity. In two respects the 

 specimens seem to be somewhat different from the common 

 description of the species; first the subgastral quadriradiates 

 are present in very small number, and next the distal cones 

 are somewhat visible ; on account of these facts the sponge 

 must be very nearly related to Sycon lingua^ though the two 

 species are for the present placed in different genera. It must
