and the epidermis appears to be darker ; the sculpture is precisely similar ; 

 the Museum possesses specimens of N. anceps from Tenasserim, also from 

 Moulmein. Dr. Anderson found N. arata tolerably abundant at Bhamo 

 and Ponsce ; the specimens from the latter locality are rather smaller and 

 are the var. minor of Blanford.

This species was found abundantly at Bhamo and in the second defile of 

 the Irawady. The specimens are quite undistinguishable from others in the 

 Museum from Mergui (typical locality) . I think it doubtful if Godwin- 

 Austen's N. atricolor from the Shisha Valley will prove really distinct. 



The figure in the Con. Indica, pi, 5, fig. 4, is not characteristic of the 

 species j it appears rather to represent N. vitrinoides.

A single specimen of this well-marked species was found at Bhamo ; 

 there are also specimens in the Museum from Pegu, Arakan, and Mergui.

This species a good deal resembles an Assam form ; its thicker and 

 more shining substance, less open perforation, less oblique j^eristome (which 

 is considerably more broadly reflected, nearly covering the perforation) , and 

 its possessing a whorl less will, however, distinguish it. Typical JST. Jiones- 

 ta, as admirably figured in the Con. Indica, pi. 90, fig. 10, is found at Pegu, 

 Moulmein, and Thyet-Myo ; var. andersoniana at Thyet-Myo, Sibsagar, 

 Naga and Khasi Hills, Chittagong, and East Cachar ; Dr. Anderson also found 

 it at Ponsee, Ava, Nantin, and 2nd Defile (Irawady). This variety is dis- 

 tinguished by its less depressed shape, it is scarcely if at all angled at the 

 periphery (the angalation being very distinct in type form), the j)eristome 

 not quite so broadly reflected over the perforation ; the substance and tex- 

 ture, perforation, shape of the aperture, and number of whorls are identical.
