ART. 5 LUZON LAND SHELLS BARTSCH 15 



The type, Cat. No. 219021, U.S.N.M., has 5 whorls and measures- 

 height, 43.6 mm.; greater diameter, 35.6 mm.; lesser diameter, 

 30.0 mm. 



The elongate form, very oblique, aperture and reduced color bands 

 characterize this race, which comes from Donsal, Sorsogon Province, 

 Luzon.

Shell rather large, subglobose, early whorl pale brown or white, 

 the later turns may be soiled white with a yellowish tinge, pale 

 straw-colored, wax yellow, or almost orange in general tone. In 

 all our shells there is a dark umbilical area and in all, even those 

 that appear unicolor, at least a slender thread of brown is apparent 

 at the summit. The peripheral zone of brown may be present or 

 absent, the same is true of the spiral band between the periphery and 

 the summit. All three spiral bands are broad and very pronounced 

 in some shells. Aperture large, broad. Peristome expanded, 

 thickened, and reflected, white. 



I have selected a dark colored specimen as type, Cat. No. 312955, 

 U.S.N.M., which is figured on Plate 7, Figures 4-6. This has 5 

 whorls and measures — height, 39.7 mm. ; greater diameter, 34.6 mm. ; 

 lesser diameter, 29.8 mm. Another specimen showing the full 

 banding is shown on Plate 7, Figures 7-9. 



This race, which also comes from somewhere in Albay Province, 

 Luzon, resembles most nearly Cochlostyla persimilis callipepla^ 

 from which its much larger size will distinguish it at once. 



COCHLOSTYLA PERSIMILIS PODAGRA, new subspecies 



Plate 8, Figures 7-9 



Shell helicoid, thin. Early whorls pale yellow, the succeeding 

 turns gradually becoming darker, grading to brownish green on the 

 last portion of the last whorl. The area about the umbilicus is 

 dark chestnut brown, a band of the same color marks the periphery 

 and another of the same shade is a little nearer the peripheral band 

 than the slightly paler one at the summit. In tlie type an additional, 

 very pale brown zone is present halfway between the band at the
