Henrx rysa, ‘ Crag Moll.,’ vol. i, p. 4, Tab. I, fig. 1, must for the present retain that 
name. I have not been able to find an existing species to which it can be referred. ‘The 
specimen I figured was then unique. Mr. Canham has obtained from the “ diggers” at 
Waldringfield a second individual, which, he says, came out of the Red Crag at that locality.

A specimen of this species has recently been found in the Red Crag at Butley by Mr. 
A. Bell, which I have had figured, and another by Mr. Harmer at Bramerton; each of 
these shows a tooth in the aperture. My specimens from Clacton and Stutton are nearly 
all endentulous. I have given to this shell the above name, having previously used it in 
my former ‘ Catalogue.” ‘The confusion respecting the true muscorwm of Linné still exists, 
and perhaps may never be cleared up, but the muscorum of Miller appears to be admitted, 
and this name is entitled to precedence before that of marginata, Mont.

Locality. Red Crag, Butley. 
This specimen was found in the Red Crag at Butley by Mr. A. Bell, and I have assigned 
it, though with doubt, to the above-named species ; it is shorter and more inflated than 
any of our British species. This specimen is in the cabinet of Mr. Reed, of York, Fig. 
8, 6, Tab. I, ‘ Crag Moll.’ vol. i, may, perhaps, be referred to the same species, and fig. 
8, a, of the same plate may be what Moller described as Z. Holbolliz, which is more 
elongated, and it has a larger umbilicus. I have several specimens of this from Butley- 
These appear to represent the existing northern forms of this genus.
