Ascetta primordialis, Haeckel. 



Denne Svamp er fondet paa Station 35 i et mindre 

 og et større Exemplar og paa Station 275 et stort Nar- 

 dorusexemplar fastsiddende paa Roret fra Onuphis conchy- 

 lega. 



Ascetta blanca, Haeckel. 



Fra en ukjendt Station 2 Exemplarer, det ene 3™ 

 langt og 1,4™ bredt, det andet 1,4"" langt. Naalene er 

 større end de af Haeckel opgivne Maal, saaledes fandt jeg 

 Basalstraalen paa en Naal 0,308""" lang og de to orale 

 Straaler 0.244""", og Naalene er kun enkeltvis stumpe for 

 Enderne, Mesteparten har spidse Straaler.

Sycandra arctica, Haeckel. 



Exemplarer af denne Svamp er fondet i Saltstrommen 

 paa 90 Favnes Dyb og paa en ukjendt Station, samt paa 

 Station 40 og 283. 



Sycandra raphanus, Haeckel. 

 Findested. 



Station 35. 



Ascetta primordialis, Haeckel. 



One small, and one larger, specimen of this sponge 

 was found, at station No. 35; and at station No. 275. a large 

 Nardorus specimen was found, seated, firmly, on the tube 

 of an Onuphis conchylega. 



Ascetta blanca, Haeckel. 



Of this sponge, 2 specimens were obtained at a sta- 

 tion the record of which has been lost. The one specimen 

 measures, 3™ in length, and 1.4™ in breadth; and the other 

 specimen 1.4'"' in length. The spicules are larger than those 

 mentioned by Haeckel. I found, for instance, the basal ray 

 in a spicule, to measure 0.308""" in length, and the two 

 oral rays to measure 0.244'"'" in length. The spicules are. 

 only, occasionally, blunt at the extremities, and the greater 

 number have acuate rays. 



Leucandra Egedii?, Haeckel. 

 The classification of this sponge is uncertain.
