1876.] collected during the Dafla Expedition. 179 



with sides rather flat, penultimate and antepenultimate whorls about equal, 

 the last whorl has the constriction in the middle of the aperture, and ascends 

 to it. Apertiu'e vertical, columellar margin angular below, the tooth well 

 developed and placed low down ; outer margin rounded. Peristome thick, 

 doiible, both lips continuous and well reflected on outer margin. 



Alt. 0-24, diam. 0*14, diam. apert. 008 in. 



Hab. — In forest on the peaks of Toniputu and Shengorh, very 

 abundant. 



This species is conspicuous from its large size and tumid flat- sided 

 fomi. I have named it after Lieut. H. Home, R. E., who, with his company 

 of Sappers, rendered so much assistance in clearing the peak on which 

 I first found this shell ; and it is with feelings of extreme regret that I 

 have to record the death by sun-stroke a few months after of this able, 

 zealous, fine young officer. 



DlPLOMMATITSTA LEVIGATTJS, n. Sp., PL VII, Fig. 7. 



Shell dextral, tumidly fusiform, colour pale horny, very smooth through- 

 out, slight close colouration on the four apical whorls. Spire rather rapid- 

 ly diminishing towards the apex, this is rather sharp in some specimens. 

 Suture moderately impressed. Whorls 7, antepenultimate the largest and 

 swollen, the penultimate constricted in front of the aperture, the last 

 ascends but slightly and is puckered on the posterior margin, corresponding 

 with the angidar projections of the outer lip. Aperture vertical ; peristome 

 solid, double, the inner lip continuous, circular, the columellar process or 

 tooth moderate, the outer lip with an undulating margin, square below, 

 with angular projections, two below and one on the upper outer margin. 



Alt. 0-15 in. 



Hab. — The Dikrang valley, Dafla Hills. 



This is a very distinct form from any I am acquainted with : the waved 

 margin and angular expansions on the outer lip are its most peculiar cha- 

 racters, and mark at once its distinctness.

Hab. — Dafla Hills. The small variety like that of the Naga Hills. 

 Only two obtained, the shell appearing to be rare on this side. 



Stkeptattlus Blanfoedi, Bs., PL VIII, A, Pigs. 2, 3, & 4. 



Hab. — Harmutti, the Tanir ridge, and Dikrang valley ; one only from 

 7000 feet, — an abundant shell in the low ground. 



The true typical form ranges from 1000 to 4000 feet as a rule. There 

 are, however, two other forms, one of which has been alluded to by Mr. W. T. 

 Blanf ord in his paper on the ' Classification of the Cyclostomacea of
