Helicostyla woodiana reevi. The peristome is also much darker in the 

 present form. The spiral banding in the type would indicate that it is 

 probably as variable in this subspecies as in the other forms that consti- 

 tute Helicostyla woodiana. 



The type, Cat. No. 219029, U. S. N. M., comes from Paracale, Ambos 

 Camarines, Luzon. It has 5.5 whorls and measures: height, 75 mm.; 

 greater diameter, 59 mm. ; lesser diameter, 46 mm. 



Geophorus agglutinans Ieytensis, new subspecies. 



Shell similar to Geophorus agglutinans agglutinans Sowerby, but much 

 smaller, with the upper portion of the whorls bright chestnut brown, 

 excepting a narrow yellow zone at the summit and another at the peri- 

 phery. In Geophorus agglutinans agglutinans Sowerby, the upper surface 

 is bright yellow. The base of the present subspecies has a broad brown 

 band covering the anterior third, which is separated from the periphery 

 by a narrow yellow zone ; the rest is yellow. In Geophhorus agglutinans 

 agglutinans the base is inclined to be unicolor, or if a band is present it 

 is merely indicated. 



The type and another specimen, Cat. No. 219023, U. S. N. M., come 

 from Jaro, Leyte. The type has 5.5 whorls and measures: altitude, 8.3 

 mm. ; greater diameter, 13 mm. ; lesser diameter, 11.3 mm. Four addi- 

 tional specimens are in Mr. Webb's collection. A cotype of Geophorus 

 agglutinans agglutinans collected by Cummings at Dingle, Panay, has 5 

 whorls and measures: altitude, 9.5 mm.; greater diameter, 17.6 mm.; 

 lesser diameter, 14.7 mm. 



Vivipara cebuensis boholensis, new subspecies. 



Shell similar to Vivipara cebuensis but in every way much larger than 

 that form with the umbilicus much wider and much less covered. The 

 obsolete shoulder is more pronounced in the present form, while the fine 

 spiral sculpture is decidedly less developed. There is also a tendency 

 toward obsolete maleations on the last turn. 



We have seen two specimens of this subspecies from Bohol, the type, 

 Cat. No. 219002, U. S. N. M., and another specimen in Mr. Walter F. 

 Webb's collection. The type has lost about the first half turn, the 5.5 

 remaining measure: altitude, 36.5 mm.; greater diameter, 27.5 mm.; 

 lesser diameter, 22.5 mm.
