316 H. H. Godwin-Austen — On the Helicidse collected [No. 4, 



Glessula orthoceras, G.-Austen. Splendid specimens of this shell were 

 ohtained at Harmutti and in the Burroi Gorge, where it was very common. 

 The largest measure as much as 2*85 in length by 05" in major diameter. 



Glessula Gassiaca, Bs. Toruputu. 



Glessula Daelaexsis, n. sp., Plate VIII, Fig. 10. 



Shell elongately turreted, thick, obliquely striate, covered with a thick 

 olive-green epidermis with a few dark streaks. Spire turreted, slightly 

 convex in outline, apex blunt ; whorls 11, rather flat, specimens with 

 apex preserved shewing erosion of the surface. Suture well marked. 

 Aperture oblique, suboval, pale grey. Peristome acute, columellar margin 

 slightly curved and but little thickened. 



Alt. 1-9", major diam. 0-41", alt. ap. 0-42". 



Hab. — Shengorh Peak, rather abundant. This shell would appear to 

 have a close connection with G. erosa, H. Blf ., from Darjiling, but its much 

 longer form, greater number of whorls, and the different colour of its 

 epidermis (which is uniform throughout), at once distinguish it. As in 

 G. erosa the position of former apertures is distinctly indicated on the whorls. 



Bulimtts Masoni, n. sp. 



Shell sinistral, acuminately oblong, thick, side of spire rather flat, 

 whorls 7, smooth and shiny, under lens finely and spirally striate, colour sea- 

 green, intenser below the keel, paling towards the apex, the columella dark 

 purple, a narrow fillet of same colour borders the suture closely below, 

 commencing at the upper and outer angle of the aperture. Aperture oval, 

 angular above, lip slightly reflected. The last whorl slightly keeled. 



Alt. 1-2", major diam. 0-5". 



Hab. Dihiri Parbat, 2000 feet. Only two specimens were found. 



This handsome Bulimus is very similar inform to B. Sylheticus, Peeve, 

 but this latter shell is smaller, exhibits no trace of spiral striation, has its 

 surface more polished, while the columellar margin and outer lip is pure 

 white ; and in dozens I have collected no trace of a band is ever seen. In 

 colour too B. Sylheticus differs from the new form in being lemon-yellow with 

 a greenish tinge on the body whorl. Peeve, I notice, erroneously describes it 

 in the Conchol. Icon. Bui. 564 as bright yellow, and makes a great blunder 

 about its habitat, which is given as " Sylhet, Eastern Himalayah," Sylhet 

 being a district south of the Khasi Hills in the plains of Lower Bengal. 

 The true home of B. Sylheticus is the southern slopes of the Khasi and 

 Garo Hills ; the title is therefore unfortunately misleading. 



I have named this species after Mr. J. Wood-Mason, to whom I am 

 indebted for much valuable aid both in securing collectors and preparing 

 equipments for the field.
