Reniera oblonga, n. sp. 



Svagt gultfarvede pølseformige Svampe med en ujevn 

 hullet og toppet Overtrade, der kun indeholder ac 2 , let 

 krummede Naale, der kryclse hinanden i alle Retninger.

Station ukjendt. 



Reniera velamentosa, n. sp. 



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

 med en Axe af noget fastere Konsistents, fra hvilken 

 der udgaar Bjelker til en meget tyncl Overfladehinde, i 

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

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

 Fig. 10 og Tab. VI, Fig. 3.

Reniera tnbulosa, n. sp. 



Et Brudstykke af en Svamp, en Plade, paa hvilken 

 der sidder 5 Bør af 2 — 3 cm Længde; da disse Bør aabne 

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

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

 sluttet en større Hulhed, ind i hvilken Børene har havt 

 sin Udmunding, idet disse siclste rimeligvis har været Svam- 

 pens Oscula. Det bringer en til at tænke paa Bev. for- 

 manns Beskrivelse af Oceanapia Jeffreysii 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, eler 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 2 spicules, slightly curved, and intersecting each other 

 in all directions. (PL II, fig. 5, PL VI, fig. 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 etc 2 spicules occur. Only such spicules are to 

 be found in the entire sponge. (PL I, fig. 10, PL 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 cm 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 l ; but in our fragment, no bihamate 

 spicules are found, only ac 2 spicules being visible (PL I, 

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

Station No. 1. 



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-
