ALTCJiiTTS LAHUPAENsis, 11. sp. (Plate CXLI. figs. 3, 3 a.) 



Locality. Gaziphimi, Lahupa iSaga Hills, Munipur {Godwin- 

 Austen). No. 2656 13. M. Type, 



Shell globosely turbinate, umbilicus fairly open ; sculpture at 

 the sutural tube is fairly strong, regular, close costulation, becoming 

 gradually finer towards the apical whorls ; colour whitish or very 

 pale ochraceous ; spire depressedly conoid ; suture impressed, the 

 sutural tube short ; whorls 4|, well rounded, last crossed by a low 

 ridge between the aperture and sutural tube ; aperture ovate, 

 angulated above, rounded below ; peristome very solid, double, 

 very slight crenulation -visible on the outer margin but not inside 

 the aperture ; columellar margin nearly vertical, sinuate. 



Size : maj. diam. 4*0 ; alt. axis 1-8 mm. 



At a first glance, this shell might be taken for A. kJiasiacuf!, 

 G.-A., J. A. S. B. vol. xl. 1871, pi. iii. fig. 4, the type of which is 

 from the Garo boundary of the Khasi Hills ; but on placing the two 

 side by side, there is considerable difference in its size, longer 

 sutural tube, aperture not so circular and the peristome larger, so 

 much more thickened. 



An Ah/cceics, unfortunately a single specimen and imperfect, was 

 sent to Colonel Beddome by Mr. Muspratt, of the Assam Police, 

 from the Naga Hills, probably the Eastern. It appears to be a 

 new species and somewhat similar in appearance to A. lahvpaensis, 

 the sutural tube being short, but it is much larger, being 5'3 mm. 

 in major diameter. No. 287, Bedd. Coll. B.M. 



Alyo^us LEVIS, n. sp. (Plate CXXXYIII. figs. 3, 3 a.) 



Locality. Munipur, No. 2631 B.M. Coll. {Godivin-Avsten). 



Shell depressedly globose, umbilicus open ; sculpture : shell a 

 good deal worn, but very fine close costulation next the sutural 

 tube; colour bleached; spire conical, depressed; apex rounded; 

 suture moderately impressed, sutural tube long ; whorls 4^, 

 slight, constriction in front of tube and then slightly swelling 

 again ; aperture circular ; peristome double, simple, much 

 thickened; columellar margin rounded ; operculum black. 



Size : maj. diam. O'O ; alt. axis 2-7 mm. 



It is unfortunate that only one specimen occurred among the 

 shells I collected in Munipur, and the exact locality was not 

 recorded. It is in form exceedingly like a very large Alycwus 

 from Burma, A. maynus, but about half as small. 



Altc^tts logtakensis, n. sp. (Plate CLV. fig. 6.) 



Locality. Logtak Lake, Munipur (No. 2639 B.M. Coll.), on a low 

 hill near the northern shore. 



Shell closely urabilicated, globosely pyramidal; sculpture; distant, 

 strong costulation on the iij)per whorls, close, well raised, and 

 stronger at the sutural tube, and finely so anterior to it ; colour 

 whitish ; spire high conical, apex rather pointed, suture moderately
