national collection from the seas of Japan, which he believes to be at present an 

 undescribed species, and proposes to call PI. turritispira. This makes an approach to 

 the Crag shell, but it differs in having a finely cancellated exterior and a smaller and 

 shallower sinus in the lip. From the affinity which my shell bears to the existing teres 

 I have given it the name of tereoides.

Localities. Red Crag, Waldringfield, Sutton, and Butley. 



This species is given by Mr. A. Bell in his list of the " English Crags," and Mr. 

 Robert Bell has forwarded to me two specimens from Waldringfield with this name 

 attached, and I have myself found a similar one at Butley. There are also some specimens 

 in my collection in the British Museum. I give it with a mark of doubt.

Locality. Cor. Crag, near Orford. 



The shell figured is one of my own finding. Mr. Robert Bell had a very perfect 

 specimen showing the fine striae, but unfortunately it has been broken or I would have 

 had it figured. My specimen, however, shows traces of the striae, and I believe it is 

 correctly referred. Mr. Jeffreys in his list to Mr. Prestwich's paper gives this as a Red 

 Crag, but not a Coralline Crag species. I have not, however, been able to confirm the 

 reference of it to the Red Crag. 



Pleurotoma rugulosa, Phil. 



Mention is made at p. 46 of ' Supplement ' of some specimens from the Coralline 

 Crag that might be referred to this species. I have since, however, had reason to doubt 

 whether these may not be the young of some other species.
