Kugleformet eller oval. med iigjevn, graa Ovfiflade, 

 hvori undertiden er fastiicftet Svampespikler, der stritter i 

 alle Retninger. Vreggen inid, tyk. Det indre Kammer 

 indeholdende en mere eller mindre fast, kornet Masse. 

 (Se Flanellen Figg. 1—4). 



■Paa 2 Stationer meget vidt fra liinanden, nemlig 

 Station 35 og Station 295 faiidtes endel kugleforinede eller 

 ovale Klumper, i Regelen niero eller mindre d;ekkede af 

 udstraalende Svampespikler, radiært kan det ialfald ikke 

 altid kaldes, det ser meget mere ud som om de strittede ud til 

 alle Kanter, idet nogle er temmelig lange, andre afbnikne 

 et Stykke fra eller helt inde ved Roden, iivor de viser sig 

 som en mork Ring med en lys Frik i Midten. Disse 

 Spikler iiar i det indre af Klumpens livide, lose Vægge 

 tabt sin Konsistens og fuldstændig smeltet sammen med 

 det ovrige Materiale, ganske tint. glindsende Sand, til en 

 kompakt Masse. 



Det ydre har en skidden graa Kulor, modsat Tliolo- 

 sina biilla, der er mere hvidlig. og undertiden sees hvide 

 skalfragmenter fastheftede til Ydervæggene. Brudfladerne 

 derimod ligner aldeles paafaldende ThoJosiiia huIJa. 



Materialet er som for nævnt af en hvid Konsistens 

 dog sees paa nogle Exemplarer den yderste 3die Del eller 

 Halvdel af Væggens Gjennemsnit at være graa. 



T Klumpees Indre sees der altid en mere eller 

 mindre fast, kornet og gulbrun Masse. Undertiden danner 

 denne en løs, af mange smaa Mellemrum afhrudt Sulistans, 

 der fylder hele den indre Hulhed eller ogsaa viser den sig 

 som en kompakt, afrundet Blok af et forholdsvis lidet 

 Volum. 



Paa to andre Stationer, nemlig 87 og 326, fandtes 

 nogle andre Klumper, der adskiller sig fra de ovenfor om- 

 talte derved at Svampespiklerne mangler, Væggenes Brud- 



Chrithionina abyssorum n sp. 



Spiierical or oval, witb uiieven. gray surface, on 

 which there are soraetimes sponge spicules sticking out in 

 all directions. Wall wliite, thick. Tiie inner chamber 

 containing a more or less tinn, granular mass. (See plate, 

 figs. 1 — 4). 



At 2 stations, at a great distance from one another, 

 namely Station 35 and Station 2t)5, a number of sperical, 

 or oval lumps were found. generally more or less covered 

 with outward-streaming sponge spicules, wiiicii could not 

 always, at any rate. be said to be radial; they appear 

 rather to bristle out in all directions, some being long, 

 others broken off a little way from, or closc to the root, 

 whei-e they look like a dark ring with a light dot in the 

 centre. In the interior of the white, loose partitions of 

 the lunii), tliese spicules have lost their consistency, and 

 become completely nierged in the other material, very fine, 

 glittering sand, into a compact mass. 



The exterior is of a dirty gray colour, unlike TJio- 

 losina hulla, whicii is whiter, and fragments of shell are 

 sometimes seen attached to the outer walls. Fractured 

 surfaces, on the other hand, bear a most striking reserab- 

 lance to Tholosiiia biilla. 



The material, as before nientioned, is of a white 

 consistency, altiiougli in some specimens, the outermost Ys 

 or Va of the section of the wall is found to be gray. 



In the interior of the lump there is always a more 

 or less firm, granular. yellowish brown mass. Sometimes 

 this is a loose substance, interrnpted by a number of 

 small intervals, and filling the entire inner cavity ; or it 

 appears in the form of a compact, rounded block of com- 

 parativelly small bulk. 



At 2 otlier stations, wiz. 87 and 32G: were found 

 other lumjis dififering from those already inentioned, in the 

 abseuce of sponge spicules, and in the fact that the frac-
