Chrithionina abyssorum n. sp. 



Kugleformet eller oval, med ugjevn, graa Overflade, 

 hvori undertiden er fastheftet Svampespikler, eler stritter i 

 alle Retninger. Væggen hvid, tyk. Det indre Kammer 

 indeholdende en mere eller mindre fast, kornet Masse. 

 (Se Planchen Figg. 1—4). 



Paa 2 Stationer meget vidt fra hinanden, nemlig 

 Station 35 og Station 295 fandtes endel kuglef ormede eller 

 ovale Klumper, i Regelen mere eller mindre dækkede af 

 udstraalende Svampespikler, radiært kan det ialfald ikke 

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

 alle Kanter, idet nogle er temmelig lange, andre afbrukne 

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

 som en mørk Ring med en lys Prik i Midten. Disse 

 Spilder har i det indre af Klumpens hvide, løse Vægge 

 tabt sin Konsistens og fulclstændig smeltet sammen med 

 det øvrige Materiale, ganske fint, glindsende Sand, til en 

 kompakt Masse. 



Det ydre har en skidclen graa Kulør, modsat Tholo- 

 sina bulla, der er mere hvicllig, og undertiden sees hvide 

 skalfrag menter fastheftede til Ydervæggene. Brudflad.erne 

 derimod ligner aldeles paafalclencle Tholosina hulla. 



Materialet er som før nævnt af en hvid Konsistens 

 dog sees paa nogle Exemplarer den yderste 3die Del eller 

 Halvdel af Væggens Gjennemsnit at være graa. 



I Klumpees Indre sees der altid en mere eller 

 mindre fast, kornet og gulbrun Masse. Undertiden danner 

 denne en løs, af mange smaa Mellemrum afbrudt Substans, 

 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. 



Spherical or oval, with uneven, gray surface, on 

 which there are sometimes sponge spicules sticking out in 

 all directions. Wall white, thick. The inner chamber 

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

 figs. 1—4). 



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

 namely Station 35 and Station 295, a number of sperical, 

 or oval lumps were found, generally more or less covered 

 with outw T ard-streaming sponge spicules, which 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 close to the root, 

 where they look like a dark ring with a light dot in the 

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

 the lump, these spicules have lost their consistency, and 

 become completely merged in the other material, very fine, 

 glittering sand, into a compact mass. 



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

 losina bulla, which is whiter, and fragments of shell are 

 sometimes seen attached to the outer walls. Fractured 

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

 lance to Tholosina bulla. 



The material, as before mentioned, is of a white 

 consistency, although in some specimens, the outermost 1 / s 

 or V2 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, interrupted 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 other stations, wiz. 87 and 326: were found 

 other lumps differing from those already mentioned, in the 

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