210 Mr. W. H. Benson on new Species of Land-Shells, 
cimens, one of which exhibits the large dimensions recorded 
above. 
Helix Neherensis, B. 
HT, testa anguste et perspective umbilicata, depressa, lenticulari, 
oblique striatula, lineis concentricis vix impressis, confertissimis, 
superne et infra decussata; spira convexiuscula, apice planato, 
sutura marginata subcanaliculata; anfractibus 5, convexiusculis, 
ultimo ad peripheriam rotundato, subtus convexo, circa umbilicum 
excavato; apertura obliqua, late lunata; peristomate tenui, recto, 
marginibus callo tenui minutissime granulato junctis ; columellari 
subverticali, brevi, reflexiusculo. 
Diam. major 5, minor 4, axis 2 mill. 
Habitat ad Neher, Mahabaleshwar. Detexit S. B. Fairbank. 
This peculiar little species, which I have, at the suggestion of 
the discoverer, named after the place where it was found, appears 
to have escaped the observation of Mr. W. T. Blanford, who 
collected several new land-shells during a hurried search at the 
same locality, which is noted for its abundant rainfall durmg 
the monsoon. The delicate concentric lines are visible under 
a lens. 
Carychium Boysianum, B. 
C. testa subrimata, elongato-cylindrica, sub lente oblique minutis- 
sime striatula, translucente, nitida, albida; spira elongata, grada- 
tim attenuata, apice obtuso, sutura impressa; anfractibus 5, con- 
vexiusculis, subplanulatis; apertura subverticali, 1 longitudinis 
non equante, oblonge ovato-acuta; peristomate expanso, planu- 
lato, nonnunquam subduplici, margine dextro intus 1-tuberculato, 
parietali plica 1, columellari altera obliqua munitis, callo parietali 
expanso. 
Alt. 2, diam. vix 2 mill. 
Habitat prope urbem Agra, ad ripas fluminis Jumna. Detexit Capt. 
W. J. Boys. 
This species, discovered at the Taj, near Agra, by the late 
Capt. Boys, is closely allied to the Himalayan species C. Indicum, 
B., but is distinguished by its more elongated cylindrical and 
less rapidly attenuate form, and its flatter whorls, also by the 
narrower and more acute aperture, the right lip being straighter 
and less convex, and by the expanded parietal callus. 
Mr. Fairbank sent me a rough variety of Ancylus Verruca, B., 
of the Lower Himalaya and Rohilkhund, with the small variety 
of the Gangetic Planorbis nanus, which were taken by him in 
the Mahabaleshwar waters, with the shell imperfectly described 
by Mr. E. Layard, in the ‘ Proc. Zool. Soc,” for 1854, as Ancu- 
lotus carinatus, which bears some resemblance to Mr. Anthony’s 
North-American shell of the same name. I consider the Indian 
species to be a Melania. They were accompanied by a new
