GASTEROPODA. 3 



Helix 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. 



Pupa muscorum, Mutter. Supplement, Tab. I, fig. 7, a, b. 



Localities. Red Crag, Butley. Fluvio-rnarine Crag, Bramerton. Post-glacial, 

 Clacton and Stutton. 



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 muscorum of Linne still exists, 

 and perhaps may never be cleared up, but the muscorum of Miiller appears to be admitted, 

 and this name is entitled to precedence before that of marginata, Mont. 



LimnjEa Pingelii ? Moller. Supplement, Tab. IV, fig. 4. 



Lymnjsa Pingelii (Lymnophysa Pingelii, Beck) in Moller, Ind. Moll. Groenl., p. 5. 



" Testa ovato-elongata ; spira conica, acutiuscula ; anfr. 5; sutura profundiori ; aper- 

 tura dimidio testae longitudinis breviori ; rima umbilicali angustiori. L. 6, 5'".'' — Moller. 



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, b, 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 L. Holbollii, 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. 



Melampus fusiformis, S. Wood. Crag Moll., vol. i, p 12, Tab. I, fig. 14 (as Cono- 



vulus mgosotis), and Supplement, Tab. I, fig. 1.

Localities. Red Crag, Sutton. Fluvio-marine Crag, Thorpe, in Suffolk, and
