In one sample I saw a form whicli I think must be referred 
to this species.

p. 560. PI. 20, f. 23, 1887. 
The specimens observed differed from the quoted figure by 
Daday in being somewhat more lengthened. 
1 (rr) — 6 (rr).

This species varies much in length and shape of its inferior 
end. Some of the specimens observed may be referred to the form 
figured by Daday 1. c., PI. 19, f. 9, being longer and more 
cylindrical than usually in northern specimens. Thus they approach 
to T. Lobiancoi Daday 1. c., p. 553, PI. 19, f. 27 but none of my 
specimens was so long as figured by Daday 1. c. PI. 19, f. 27. 
2 (rr) — 6 (rr) — 10 (rr). 
Area: Apparently an ubiquitous neritic form. 
10. T. Mortensenii Schm. n. sp. 
House skort , globose or subglose, covered 
by agglutinated foreign bodies; moutli widened, 
infundibuliform. 
Length 41 g. 
Breadth 28 g. 
Diameter of mouth 53 p. 
This species may be compared with T. 
campanula from whicli it is easily distin- 
guished by the shape and smaller size of the

house. I name it in memory of my fellow-traveller, Dr. Th. Mor¬ 
tensen, who collected most of the plankton-samples examined. 
1 (rr) — 2 (rr) — 5 (rr).
