There is also the possibility of relationship with two other fossil species, viz. 
Hemithyris plicigera (Shering) and H. australis, Buckman, from the Miocene-Oligocene 
beds of the same island.

Hab.—Station 346; lat. 54° 25’ S., long. 57° 32’ W. (Burdwood Bank), 56 fathoms. 
December 1, 1903. Sea bottom, Bryozoa. ‘Temperature 41°°8 F. 
Obs.—Several dead examples of a small species of Liothyrina were trawled at the 
above station at 56 fathoms. 
The largest example (Pl. I. fig. 9) measures: length, 15°5 mm.; breadth, 
13 mm., and agrees very closely with the specimen figured by FiscHER and OEHLERT 
(op. evt., pl. viii. fig. 23) under the name of Terebratula (Lvothyrina) moseleyi, Dav. 
The two vascular sinuses show very clearly in the interior of the ventral valve, as in 
their figured example. The dorsal valve of this specimen is also interesting as showing 
a very distinct trace of a median septum, as well as a strongly developed hinge apo- 
physis, which occupies a considerable portion of the posterior end of the valve. 
Other noteworthy features are the remarkable thickness of both valves, and the 
abundance of coarse growth lines, which would lead one to infer that the shell had 
attained an adult, or even a gerontic, condition. 
Most of the other examples, though smaller in size, also show a considerable 
thickness in their shells, which renders the test quite opaque. 
All are similar in form, being somewhat pyriform, and attaining their maximum 
diameter a little anterior to the middle of the valves. 
The colour of the specimens is milk-white.
