The spocinu'ii, which is yoiinp:, as»;reos vorv well with Philippi's 

 figure of ii young' shell, but in sucli forms eouipurisou with a ratlier 

 obscure figure may always leave some doubt; Boettger has figured 

 a verj' complete speciiuen from the Gunung Salak ; 1 can gee no 

 difference in my other specimens from Java, as far as concerns shape 

 and sculpture, but of course the characters of aperture rcimiiu 

 undecided.

Hab. — Babakan, March, 1911. One specinum. 



Agreeing in shape and rather coarse sculpture with tlie e.xisting 

 figures and with specimens I could compare, the only difference is 

 that the specimen has in all five bhickisli streaks, one large preceded 

 bj^ a narrow one above the point of junction of the ])eristome, one on 

 the back of the last wliorl, and two narrow ones on tlie penultimate 

 wliorl; of these latter two I find lu) ineutiou in literature. A. penrrsiis, 

 which is a many-streaked species, is much smoother. Y. d. Jiuscli 

 has not described this species.

ITab. — Nusa Kambangan, March, 1911. One specimen. 



A little larger than Mousson's type (19 instead of 17 mm.) and 

 without the blackish top, but otherwise perfectly agreeing with his 

 desci'iption. The species seems to be rather variable in shajjc and 

 colour-markings. I possess several specimens with and without dark 

 top, with and without the brownish band in the aperture, (piite 

 white and with a peripheral baud, but all agree in their principal 

 characters.
