on the contrary all the other specimens I have taken associated 

 with it are the most strongly banded I have ever seen. As this 

 shell is so very distinct in appearance from the two described 

 species of British Paludinje...! propose, until decided whether 

 it be a distinct species or not, naming it Paludina achatina 

 \==vivipara of modern authors] v. efasciata." The navae e/asdata 

 has thus priority and supersedes Jeffreys' name unicolor. This 

 form will now stand as Paludhia vivipara v. efasciata Pickering.

Variation in the coloration of Planorbis con- 

 tortus Linn. — Collecting shells a few months ago (during June) 

 in a small pond near the Black Hills, York Road, Leeds, I was 

 astonished to see a small Planorbis^ which proved to be P. con- 

 tortus Linn., of a bright pink or scarlet color, and which was so 

 conspicuous as to attract my attention as the animal was feed- 

 ing on some plants at some distance in the pond. Having 

 secured the specimen I found that the pink color of the shell 

 was due to the color of the animal, which was of a bright scarlet 

 or carmine. — W. Nelson, Aug. ist., 1883. 



Planorbis complanatus monst. terebrum Turton. — 

 This singular form of P. complanatus is of a regular coni- 

 cal shape with very deep sutures. It is figured by Woodward in 

 his " Manual of the Mollusca," — from a specimen found near 

 Rochdale — and also by Tate in his " British Land and Fresh- 

 water Shells," and was first described by Turton as Helix terebra, 

 and afterwards by Brown as Helix cochlea. Mr. W. Jeffery, of 

 Ratham, Chichester, has been so fortunate as to find a specimen 

 in a pond in his neighbourhood which he has most generously 

 sent to me alive for the collection of the Conchological Society. 

 The specimen has the normal number of whorls and is about 5 

 mill, in diameter with an altitude of 7 mill. The animal does 

 not appear to differ from the normal form. — J. W. Taylor, Sep. 

 6th, 1883.
