It is found in its restricted form, rather abundantly at a few 
Stations, mostly in Area 1.

In abundance this species almost equals T. squamata, and is rather 
more widely distributed. The specimens, as usual, have the primary 
chambers of a dark colour. 
There are but few records of the occurrence of this species outside 
the British Isles. Brady gives no ‘ Challenger ’ Stations, but in the 
‘ Summary of the Scientific Results ’ it is reported from Stations 
237 and 323. Berthelin reports it from Belgium, Cherbourg, and 
from Bourgneuf and other places in the Bay of Biscay. Robertson 
procured it from the coast of Spain, and Goes from the Baltic. The* 
‘ Gazelle ’ stations from which it was obtained are not named.

This variety differs from the type not only in the indentation of 
the chambers, but also in its tendency to the nautiloid form of growth. 
It occurs sparingly at a few Stations in the Malay Archipelago.

This species is very abundant, and occurs at several Stations in 
both Areas. The punctation or reticulation of the interior surface is- 
not apparent. 
In the ‘ Gazelle ’ examples, which are from West Africa and West 
Australia, the aperture is porous. Goes reports it from the Pacific 
and the Caribbean Sea.
