PHILIPPINE LAND SHELLS BAKTSCH. 



11 



Shell elongate-ovate, whorls moderately rounded, marked by in- 

 cremental lines only. The first three whorls have a narrow, black 

 band appearing above the suture, while the rest is white. The 

 remaining turns are yellowish white, profusely spotted with irregu- 

 larly shaped blotches of chestnut brown, which are bordered by a 

 lighter area and usually preceded by a white area. There are no 

 strongly developed varicial streaks; if shown at all they are indi- 

 cated as mere faint lines. 



The type of A. maculiferus was collected by Hugh Cuming in 

 Misamis Province, Mindanao. The material which I have examined 

 comes from the same region. The following table gives additional 

 data as to number of whorls and measurements : 



AMPHIDROMUS MACULIFERUS CATAGANENSIS, new subspecies.

 pi. 100, figs. 2-3. 



Shell ovate, dextral, or sinistral. Whorls well rounded, appressed 

 at the summit and marked by lines of growth only. Sutures strongly 

 constricted. Aperture moderately large; outer lip expanded and 

 reflected ; inner lip almost vertical, slightly twisted and reflected over 

 the narrow umbilicus ; parietal wall covered with a moderately thick 

 callus. The first two volutions are bordered with a narrow black 

 band at the suture, the rest being white ; the next two are yellowish 

 white, while the succeeding may have the same ground color or they 

 may be suffused with a rosy blush and are marked by irregular, wavy, 

 somewhat protractive, brown axial bands and a few irregularly 

 placed, scattered spots of brown which are usually preceded by a 

 lighter area. 



The type and two specimens of this species were collected by Lieut. 

 Col. Edgar A. Mearns at Catagan, Mindanao, on the Mount Mai-
