Mr. W. H. Benson on new Species of Pupa and Ancylus. 139 



Theobald. Pupa Himalayana, Huttoii (Annals, Dec. 1863), 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 itnpressa, submarginata ; anfractibus 7-7^, convexis, ultimo 

 antice ascendente ; apertura semiovata, subobliqua, edentula ; 

 peristomate expansiusculo, albido, margine dextro extus postice 

 incrassato. 



Long. 2^, 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 being 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. 1^, diam. 1 mill. 



Habitat prope Liberiam Africse 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 belir f that a portion of the animal 

 is scarlet, as in Ennea hicolor and several Mauritian Pupae. 



Ancylus Ceylanicus, B. 



A. testa suboblonge conoidea, antice convexa, postice concava, extus 



tenuissime radiato-costulata, costis subremotis elevatioribus munita, 



striis confertis concentricis decussata, viridescenti-cornea, margine 



lato, lutescenti-cornea, apice submediano, subelongato, postice at-
