in the same bleached and weathered state, only one of them 

 having a clear rosy tinge at the apex. It is noted, as well as 

 A. constrictus, as occurring in the Rungun valley, and, being 

 evidently abundant, ought, like A. stranyulatus, to be found 

 alive in damp masses of fallen leaves. 



AlyccEus Urnula, B. 



Several specimens in a bleached state accompany the collec- 

 tion, one of them reaching 6 mill, in length, and allowing a 

 more full comparison with the nearly allied Burmese A. Amphura. 

 Dead specimens may be distinguished from the latter by the 

 shorter sutural tube, the slightly expanded, not double peri- 

 stome, and by the absence of a slight angular compression round 

 the umbilicus, — a character which I neglected to note in my 

 description of Amphora. A. Urnula is an inhabitant of the 

 Rungun valley. 



When we find that a single valley below Darjiling furnishes 

 eight out of the nine species which it has been my good fortune 

 to describe from that neighbourhood, what an accession to the 

 genus may not be expected from further researches in that 

 quarter, in the vales of Xipal, and especially in Bootan, stretch- 

 ing towards the more humid region of the Khasia range, which 

 has supplied, from a single spot, two other distinct species of 

 this most interesting little genus ! 



7. Diplommatina Pullula, n. s. 



Testa iniperforata, ovato-turrita, oblique confertim costulata, fulves- 

 centi-albida, versus apicem rubella, spira subturrita, sutura ini- 

 pressa, apice obtusiusculo ; anfractibus G-7 convexis, antepenul- 

 timo tumidiore, ultimo antice valde ascendente, costulis remotioribus 

 irregularibus ; apertura subverticali, vix superne spectante, oblique 

 obovali, peristomate duplici, iuterno porrecto expansiusculo, externo 

 subreflexo, marginibus callo appresso expanse junctis, columellari 

 verticali planato intus acute unidentato basi angulato-rotuudato, 

 dextrali valde arcuato. Operc. ? 



Long. 3, diam. 1^ mill. 



Habitat in valle Rungun, ad latus occidentale. 



In form and size between Huttoni and folliculus, Pfr. ; dex- 

 trorse like the latter, though agreeing with the former in having 

 the tooth apparent on the columellar lip. The tooth is as strong, 

 in comparison with the size of the shell, as in the other more 

 Eastern species of the North Indian ranges. The more consi- 

 derable rise of the last whorl on the penultimate is a feature also 

 observable in the large Dipl. MacGillivrayi, xldams. The colu- 

 mellar base is deficient in the sharp angle observable in the 

 larger Khasia diplocheilus and Darjiling pachycheilus ; and its
