Vertigo pusiila var. albina. — Shell translucent white.— 

 Through the kindness of Mr. R. Standen, of Owens College, 

 Manchester, I have been favoured with a very beautiful and 

 perfect example of this interesting variety, one of several he has 

 been so fortunate as to find. It is, I believe, new to science, 

 and as yet unrecorded and unnamed, and is a welcome addition 

 to the British list. The specimen in my possession is in all re- 

 spects, except colour, identical with the typical form, possessing 

 the size, shape, number and arrangement of teeth as is usual in 

 the species. This variety was found by Mr. Standen associated 

 with typical V. pusiila^ V. angustior, and other uncommon 

 species amongst rejectamenta at Portsalon, near Letterkenny, 

 in Donegal County, at the latter end of May of the present 

 year. — J. W. Taylor, June 20th, 1893. 



On a variety of Cypraea cruenta Gmel. — In my 

 survey of the genus Cypraea, 1888,* a very striking variety was 

 differentiated under the name of C. cruenta Gmelin var. coloba 

 (Kolof3os Curtus). This form is always, so far as my experience 

 goes, very highly coloured, the base especially being bright 

 salmon pink, the lowest anterior tooth highly developed and 

 somewhat projecting, the shape more rounded than the type, 

 and the whole shell dwarfed in comparison with the normal 

 cruenta. Mr. Ford has, in the Feb. number of the 'Nautilus,'! 

 this year {1893), given a very succinct and accurate description 

 of this variety ; but, having overlooked the remarks in the 

 'Survey' above referred to, has re-christened the variety as var. 

 greegori of C. cruenta, the name co/oba having priority of five 

 years. A figure is given of this form, both in the 'Survey' and 

 in the 'Nautilus' (vol. vi., pi. ii.), and also in Sowerby Thes.
