M. Cumingii (KvQ.). M. rugosa (S,wa.\ns.). 



Shape Distinctly ovate-oblong Fusiform attenuated. 



Spire Obtusely turreted Sharply acuminate. 



Whorls Upper part angulated Upper part depressed. 



Ribs Distinct None; but strongly latticed 



with transverse longitudinal 

 ridges. 



Columella Four plaited Five plaited. 



Lip Outer lip very slightly crenate... Strongly crenate. 



base somewhat truncate base recurved. 



Coloration White, with orange blotches. .. White ; slight speckles and 

 and and black interrupted re- spots of brown ; no orange 

 markings volving lines or black lines. 



I have already stated what are probably the nearest allies of 

 M. riigosa ; as to M. Cumingii I doubt its belonging to the 

 subgenus Costellaria at all. It would rather seem akin to 

 M. patriarchalis (Lam.), a handsome and well known species 

 of the subgenus Pusia. It is gratifying to see my views con- 

 firmed by Herr Paetel, who has adopted this course in his 

 ' Conchylien Sammlung/ 1883. 



Again, while on this subject, I can hardly agree with Mr. 

 Tryon in also relegating M. clathrata (Reeve) to the rank of a 

 mere variety of M. Cumingii. This would appear one of the 

 most constant of all the Mitras ; of the many specimens I have 

 seen not one has ever seemed doubtful. The unusually deep 

 cancellations between the thick, obtuse ribs, and the conspicu- 

 ous brown band round the centre of each whorl, are unlike any 

 Mitra excepting M. {Costellaria) decora (Reeve), near which I 

 fancy it should be placed. 



Discovery of Helix harpa Say in Switzerland. — 



Mr. A. E. Craven has recently discovered this species in some 

 numbers at the Riffelalp, near Zermatt, at an elevation of 2,100 

 metres, under dead wood and especially under the bark of fallen 

 trees of Fimis pinea, a somewhat scarce tree in Switzerland. In 

 the Palearctic region H. harpa has been recorded previously 

 from Lapland, Finland, Norway, Sweden, and the Amour dis- 

 trict of Siberia. — J. W. Taylor, April loth, 1888.
