Reniera oblonga, n. sp. 



Svagt gultfarvede pølseformige Svampe med en ujevn 

 hullet og toppet Overflade, der kun indeholder ne' 2 , let 

 krummede Naale, der krydse hinanden i alle Retninger.

Reniera velamentosa, 



n. sp. 



En aflang, brun Svamp, meget los i sin Bygning, 

 med en Axe al' noget fastere Konsistents. fra hvilken 

 der udgaar Bjelker til en meget tynd Overtladehinde, i 

 hvilken der lindes talrige Aabninger i et Net af ac 2 Naale. 

 Der findes i hele Svampen kun saadanne Naale. Tab. I,

Reniera tubulosa, n. sp. 



Et Brudstykke af en Svamp, en Plade, paa hvilken 

 der sidder 5 Ror af 2 — 3"" Længde; da disse Ror aabne 

 sig paa Underfladen af Pladen, ser det ud, som om denne 

 kun var en Del af en større Væg, der kunde have om- 

 sluttet en større Hulhed, ind i hvilken Rørene har havt 

 sin LTdmunding, idet disse sidste rimeligvis har været Svam- 

 pens Oscula. Det bringer en til at tænke paa Rev. Nor- 

 manns Beskrivelse af Oceanapia Jeffreys!/' 1 ; men der findes 

 i vort Brudstykke ingen bihamate Spikier, kun ac 2 Naale.

Reniera membranacea, n. sp. 



Et temmelig stort, tyndt, gjennemskinnende Blad med 

 hvidlige, toppede Fortykkelser. Det dannes af ac 2 sp. 

 Naale, der ligger temmelig tæt pakkede og krydser hinanden i

Reniera oblonga. n. sp. 



Faint-yellow coloured, sausage shaped sponge, with 

 an uneven, conically pitted surface, which contains only, 

 ac - spicules, slightly curved, and intersecting each other 

 in all directions. (PI. II, tig. 5, PL VI, tig. 2).

No record. 



Reniera velamentosa, n. sp. 



An oblong, brown coloured sponge; very loose in 

 structure, and having an axis of somewhat firmer consistency, 

 from which rods proceed to a very thin superficial mem- 

 brane, in which numerous apertures forming a reticulation 

 composed of ac 2 spicules occur. Only such spicules are to 

 be found in the entire sponge. (PI. I. tig. 10, PI. VI. fig. 3).

Station No. 262. 



Reniera tubulosa, n. sp. 



A fragment of a sponge, consisting of a plate upon 

 which there are seated 5 tubes, measuring 2 to 3"" in 

 length. As these tubes debouch on the inferior surface of 

 the plate, it appears, as if the fragment was only a portion 

 of a larger wall which may have enclosed a larger cavity 

 in which the tubes have had their discharge ; as they have, 

 presumably, been the oscula of the sponge. This causes 

 one to reflect on the Rev. A. M. Norman's description of 

 Oceanapia Jeffreysii ' ; but in our fragment, no bihamate 

 spicules are found, only ac' 2 spicules being visible (PI. I, 

 fig. 12, PI, VI. tig. -4).

Reniera membranacea. n. sp. 



A rather large, thin, translucent and soft sponge, with 

 whitish conical tumefactions. It is formed of ac 2 sp. spicules, 

 which are placed, pretty closely packed together, and inter-
