1888. J MOLLUSCA FROM BURMAH. 245 



mented with similar zigzag bands at equal intervals, but which do uot 

 extend to the peripheral band ; spire conical, apex fine ; whorls 5 ; 

 aperture subvertical ; peristome of a pale yellowish tint, very much 

 thickened to the extent of 4*5 millim. 



Size: maj. diam. 4 1*5, min. 32'0, alt. axis 18*5 mm. 



16. Cyclophorus, sp. inc. 

 Locality. Shan Hills. 



Size : maj. diam. 31'0, min. 'Ib'b, alt. axis 15*0 mm. 



In form tliis shell is nearest to C. excellens, Pfr., from Moulmein, 

 particularly as regards the umbilicus and height of spire ; its mark- 

 ings differ, and the size is much smaller. I hesitate to name this 

 single specimen ; a series of examples in fresh condition is required 

 for these shells, so variable in colour. 



17. PtEROCYCLOS ALBERSI. 



Localihj. HHndet, 1200 feet. 



18. Alvc^us (Dioryx) urnula, var. 

 Locality. Pingoung, Shnn Hills, 2500 feet. 



The only difference between this and tbe Assamese form is the 

 greater length of the sutural tube in the Burmese shell. 



19. AlCjEUS sphatti, n. sp. 



Locality. Ping nig, Shan Hills, 2500 feet. 



Shell pyramidal, closely umbilicated ; sculpture very fine close 

 costulation, more distant between the sutural tube and the peristome ; 

 colour white, w"th pale lemon tinge, or horny ; spire high, rapidly 

 decreasing to a^jex, which is rather pointed ; suture well impressed ; 

 whorls 5g, convex, the last swollen, slightly constricted at the 

 sutura' tuhe, which is very short and thick, less than one millim. in 

 length ; the whorl swells again to the aperture, this is circular, 

 obhque ; peristome double, slightly reflected ; operculum not seen. 



This species is quite new ; it might be at first taken for a small 

 variety of A. pyramidalis, Bs., from the Tenasserim valley, but the 

 sutural tube is in that species very thread-like and nearly 3 millim. 

 in length ; the aperture is also very different in form, and not so 

 simple and circular. 



20. Paludomus ornatissima, Bs. 

 Locality. Between Myingyan and Hlindet. 



21. Melania, sp. inc. 



A specimen in bad broken condition, 



22. Ampullaria paludinoides, Phil., var. 

 Locality. Khyang-nyat. 



The present example agrees with a specimen in my collection from 

 Pegu. 



23. Ampullaria olea, Reeve. 



Locality. Sban Hills.
