i893.] THE BRITISH NATURALIST. 81 



Physa fontinalis, has a similar variety (which may be called flava) in 

 which the animal is yellow, with the pink buccal mass showing 

 through the transparent tissues. This variety was found by Messrs. 

 F. G. Fenn and S. C. Cockerell at Herne Bay, in England, and I had 

 the opportunity of seeing living examples. The white variety of the 

 shell of P. fontinalis also occurs at Herne Bay, but, as in the case of 

 the Zonites, it is not coincident with the pigmentless animal. Finally, 

 Limncea palustris var. flava Pascal (Mem. Soc. Lin. du Nord de la 

 France) is a third variety in which the animal is unpigmented. 



Z. cupveus, Raf. This name has priority over fuliginosus, and 

 should be adopted.

Z. indebitatus var. umbilicatus, Singley, n. var. Mr. Singley has 

 kindly sent me this from Lee Co., Texas. It is the form figured in 

 Man. Amer. Land Shells, fig. 17.

Patula convexior, Ancey. Mr. Ancey has kindly sent me a description 

 and figure of his ingevsolli var. convexior, which he now regards as a 

 distinct species. P. convexior has the spire distinctly convex, and the 

 aperture broader and less lunate. The last whorl is more depressed. 

 Certainly convexior would appear to be distinct, but Mr. J. H. Thomson 

 submitted to me 13 specimens collected by J. D. Putnam at Summit 

 Canon, Mt. Nebo, Utah, which are apparently referred to convexior by 

 Mr. Ancey, and I was not able to distinguish them from Colorada 

 examples, except that they seemed a little square viewed laterally. 

 These specimens, Mr. Thomson informs me, were seen by Mr. Ancey, 

 and in the MSS. Mr. Ancey kindly sent to me Mt. Nebo is given 

 as a locality for convexior.

Helix Jwrtensis form minor, Moq. I received from Mr. J. H. 

 Thomson 21 examples of var. lutea from Gay Head, I. of Martha's 

 Vineyard, Mass. They are perfectly uniform in colour, being all 

 yellow and bandless — I never saw such uniformity in the species in 

 any other locality. They are smallish, and one example, having max. 

 diam. 17 mill., may be referred to var. minor.
