AMPHIDROMUS, GROUP XII. 203 



Described as a variety of A. contrarius, but as von Moellendorff 

 has pertinerftly pointed out, it differs from that species in the import- 

 ant character of having a weak, thin-edged parietal callus, and no 

 nodule near the posterior angle of the aperture, nor raised ledge 

 below. I do not think it especially related to contrarius.

" Smaller than typical filozonatus, rather more solid ; last whorl 

 grayish-brown, with a yellow band around lower part ; upper whorls 

 white, with dark brown stripes interrupted by a narrow pale yellow 

 band. Alt, 28, diam. 14 mill." (Fulton).

I agree with von MoellendorfF that there is little ground for unit- 

 ing this with the Javan A. filozonatus. It may prove a variety of 

 maculatus.

Shell sinistral, elongate-conic, rather thin. Very lightly striatu- 

 late, rather glossy. Pale yellow with diluted-brown streaks, interrupted 

 by one or several zones of the ground color above, continuous on the 

 last whorl, the apex violet black, following 1J whorjs uniform red- 

 dish. Whorls 7-j, rather flat, the suture narrowly appressed. Aper- 

 ture three-sevenths the length of the shell, the parietal wall covered 

 with a rather broad reddish callus, palatal interior pale, showing the 

 bands through ; peristome slightly thickened and expanded, whitish ; 

 base slightly rose-tinted, columellar margin rather wide, white, dis- 

 tinctly differentiated from the parietal callus (Mortens). 



Length 44, diam. 17, aperture 15 mill.
