Mr. W. H. Benson on new Species of Pupa and Ancylus. 139 
Theobald. Pupa Himalayana, Hutton (Annals, Dec. 18638), an 
elongate and strongly sculptured shell, is the only edentate 
species previously described from the Himalayan region. 
Pupa Eurina, B. 
P. testa perforata, ovato-cylindrica, solidiuscula, suboblique stria- 
tula, rufo-castanea, nitidula; spira ovato-cylindrica, apice obtuso, 
sutura impressa, submarginata ; anfractibus 7-73, convexis, ultimo 
antice ascendente; apertura semiovata, subobliqua, edentula; 
peristomate expansiusculo, albido, margine dextro extus postice 
incrassato. 
Long. 23, diam. 1 mill. 
Habitat ad Tribeni Ghat fluminis Gogra. Detexit W. Theobald. 
This shell closely approaches the edentulate variety of P. mar- 
ginata, Drap. (muscorum, L.), in form and aperture. It is much 
larger than the British specimens of that species, and more 
solid, and may easily be distinguished by its decided perforation, 
instead of beg merely rimate, and by the margination of the 
suture. The specimens sent by Mr. Theobald were all derelict, 
and some are deficient in colour. 
Pupa Ofella, B. 
P. testa vix rimata, globoso-ovata, confertim striatula, albido-vitrea, 
translucente, polita; spira subovata, superne convexa, apice ob- 
tuso, sutura impressa ; anfractibus 4, convexis, ultimo antice non 
ascendente ; apertura vix obliqua, angulato-ovata, 4-dentata, plica 
parietali mediana curvata duplici subdenticulata intrante, dente 
columellari marginali magno crasso bicruri palatalibusque 2 mar- 
ginalibus (superiore infra elongato, inferiore acuto) munita; peri- 
stomate incrassato. 
Long. 14, diam. 1 mill. 
Habitat prope Liberiam Africze occidentalis. 
This minute shell (long mislaid) has been several years in my 
possession: it fell out of the interior of one of several shells 
from Liberia, and appears to have been overlooked by collectors, 
and not to have been obtained by the describers of species from 
that part of Africa. The shell is in excellent condition, and its 
animal had probably crept with it into the aperture of the de- 
serted shell of another species. There is a bright red appearance 
internally, which leads to the belicf that a portion of the animal 
is scarlet, as in Ennea bicolor and several Mauritian Pupe. 
Ancylus Ceylanicus, B. 
A, testa suboblonge conoidea, antice convexa, postice concayva, extus 
tenuissime radiato-costulata, costis subremotis elevatioribus munita, 
striis confertis concentricis decussata, viridescenti-cornea, margine 
lato, lutescenti-cornea, apice submediano, subelongato, postice at-
