near the aperture having no counterpart in any otlier form with 

 which I am acquainted. In other respects it is somewhat similar 

 to A. diagonius, m the strong thick peristome and closely-wound 



whorls."

 figs. 5-5 c. 



Alyc^us eoxundatus, n. sp. No. 2543 B.M. Type. (Plate 

 CLIV. fig. 6.) 



Locality. Dafla Hills. 



Shell well umbilicated, globosely conoid, with a strong epidermis ; 

 sculpture indistiuct and somewhat irregular, fine costulation on 

 upper whorls, close and fine on the swollen portion near the rather 

 long sutural tube ; colour umber-brown ; spire moderately high, 

 apex fine ; suture impressed ; whorls 4, rounded, between the 

 sutural tube and the aperture there is a slight swelling, this part 

 quite smooth ; aperture irregularly oval, slightly angulate above ; 

 peristome simple, double, somewhat thickened on lower margin, 

 curved on the columellar side, slightly reflected. 



Size : maj. diam. 4"8 ; alt. axis 2-2 mm. 



The shell is very similar to A. syllieticus. 



ALTCiEus EUGOSTTs, n. sp, No. 2G41 B.M. Type. (Plate CXLI. 

 figs. 7, 7 a.) 



Locality. Burroi Gorge, Dafla Hills {Godivin- Austen). 



Shell globosely conical, umbilicus much constricted ; sculpture, 

 well defined, close costulation next the suture, becoming for a short 

 distance behind finer and then at once becoming strong and distant 

 on the upper whorls ; colour whitish ; spire high, conical ; suture 

 well-impressed, the sutural tube not very long ; whorls 5, well 

 rounded, the last crossed by a single strong ridge between the 

 constriction and the aperture ; aperture angularly oval, oblique ; 

 peristome much crenulated, on the outer and lower margins double ; 

 columellar margin subobliqiie, curving. 



Size ; maj. diam. 3'0 ; alt axis 1-8 mm. 



I have compared this species with Alycmus crispatus from the 

 Western Khasi, Garo Frontier, and with crispatus, var. from the 

 Diyung Valley near Asalu (vide plate iv. figs. 1 & 2, J. A. S. B. 

 vol. xl. 1871), and although a close ally, it differs considerably 

 from both, being much more conical, and with a diS"erent con- 

 stricted area.
