Jeffreys. 
Yar. 1. Macandrei ) F. & H. 
A produced form, of which several specimens were 
dredged by MacAndrew 15 miles south of Mizen 
Head, south of Ireland. The form approaches that 
of L. hulimoides ) d’Orb., but the shell is smaller 
and more delicate than in that species and the suture 
more deeply cut. 
[Yar. 2. Jeffreysii , F. & H. 
Only a single u very young shell” was found. 
Stated by Jeffreys himself to be only the young.]

It was also procured in the North Atlantic in the * Yalorous’ 
expedition, by the ‘ Challenger ’ off the Azores, and by the 
c Travailleur ’ in the Bay of Biscay.

Pelseneer (‘ Challenger ’ Beport) records this species, which 
occurs in all the oceans except the Arctic and Antarctic, as 
u found by the first i Porcupine ’ expedition, 1869.” I do not 
know whence he procured the information, as I have no remem- 
brance that Jeffreys has recorded it. It may be that speci- 
mens are preserved in the British Museum. It depends upon 
the station at which it was found whether it can be included 
in our lists.]
