 har Buer og S-formede Naaie. 



Desmacidon clavatum, n, sp. 



Et aflangt Hoved paa en rund Stilk; denne hvid, 

 Hovedet gult (Tab. II, Fig. 11). I Stilken saavelsom i 

 Hovedet ac 2 og trac Naalé samt særligt i Periferien af 

 Hovedet, men ogsaa spredt inde i samme anc 2 6 (Tab. M, 

 Fig. li;. 



Findested. 



Station 51. 



Desmacidon nucleus, n. sp. 



JSTøddekjernestor, brunlig Svamp med glat Overflade. 



Den har trac Naale, der krydse hinanden i alle Retninger 



og med sine Spiclser rager ucl over Overfiaden. Denne er 



ellers dannet udelukkende af ane 2 6 Naale, der her ligge 

 tæt pakkede; men som ogsaa åndes forresten spredt inde i 

 Svampen (Tab. III, Fig. 1, Tab. VI, Fig. 17). 



Findested. 



Station 48. 



Desmacidon giganteum, n. sp. 



En meget stor, ca. 22 cm lang Svamp, der i den nedre 

 Del dannes af en Stilk af spiralsnoede Naale, udenpaa 

 hvilke der tindes en ca. l mm tyk blødere Skorpe, og hvis 

 øvre Del er noget tykkere og besat med en Masse papille- 

 formige Udvæxter, der er tykkere for Enden end veel Basis 

 (Tab. VII, Fig. 8). 



Svampen er svagt gulfarvet. Den spiralsnoede Axe 

 bestaar udelukkende af lange ac 2 og trac JNTaale [og i den 

 gultfarvede Skorpe ligesom i dens papilleformige Udvæxter 

 forekommer samme Slags Naale, men af mindre Kaliber, 

 samt ane 2 6, ligesom hos den foregaaende fornemmelig sam- 

 menhobede i Periferien (Tab. II, Fig. 12, 13). 



their structure, or in the form of the spicules, except in 

 regard to one species which has, besides anchors and bows, 

 also, S-formed spicules. 



Desmacidon clavatum, n. sp. 



An oblong head on a round stem. The head is yel- 

 low, and the stem is white in colour (PI. II, fig. 11). Both, 

 in the stem and in the head, ac 2 and trac spicules ; also, 

 especially, in the periphery of the head, but also inside 

 of it, ane 2 6, spicules are found (PI. II, fig. 11). 



Habitat. 



Station No. 51. 



Desmacidon nucleus, n. sp. 



A brownish sponge, of the size of a nut kernel; with 

 a smooth surface. It has trac spicules intersecting each 

 other in all directions, and having their apices projecting 

 beyond the surface. This is, otherwise, formed exclusively 

 of anc 2 6, spicules, which are, here, placed closely packed, 

 but which, also, are found dispersed inside the sponge (PI. 

 Ill, fig. 1, PI. VI, fig. 17). 



Habitat. 



Station No. 48. 



Desmacidon giganteum, n. sp. 



A very large sponge, measuring nearly 22 cm in length, 

 and whose inferior part consists of a Jstem of spirally 

 twisted spicules ; outside of which, there is found a thick 

 softish crust, about l mm thick; but with the superior part 

 somewhat thicker, and beset with a multitude of papilla- 

 shaped warts whose extremities are thicker than the base (PI 

 VII, fig. 8). 



The sponge is pale-yellow in colour. The spirally 

 twisted axis consists, exclusively, of long ac 2 and trac spic- 

 ules, and in the yellow-coloured crust, as also in the papilla- 

 formed warts, the same kind of spicules appear, but of 

 smaller calibre; also anc 2 6, which are, as in the pre- 

 ceding specimen, principally, collected together in the peri- 

 phery (PI. II, figs. 12, 13).
