Bartsch — New Murine Mollusks from the Philippines. 187 



extreme posterior portion smooth, the anterior three-fourths marked 

 by twelve incised spiral lines which become irregularly more closely spaced 

 from the suture anteriorly, and the spaces between them become regularly 

 more elevated, forming broad low rounded cords in the columellar region. 

 Aperture irregular, decidedly channeled anteriorly, posterior angle obtuse; 

 outer lip somewhat sinuous, reinforced by a strong callus within, which 

 bears twelve strong oblique denticles; columella with two oblique folds. 

 The extreme outer edge of the columcllar callus provided with seven strong 

 denticles; parietal callus becoming thickened toward the posterior angle 

 of the aperture. 



The type, Cat, No. 310,052, U. S. N. M., comes from the Batanes Islands. 

 It has 5 whorls remaining, and measures: altitude, 9.4 mm.; greater dia- 

 meter, 5.7 mm. 



I take great pleasure in naming this species for the Hon. Jaime C. de 

 Veyra, Resident Commissioner from the Philippine Islands, whose interest 

 in the natural history of our island possessions is aiding materially in 

 increasing our knowledge of their faunas. 



Sigaretus weberi, new species. 



Shell decidedly depressed, lenticular, pale yellow with a suffusion of 

 rusty red on the last turn. Nepionic whorls well rounded, smooth, very 

 small, the first turn and a half pale brown, the rest white. The nepionic 

 portion appears to coil very regularly and the turns increase but slightly 

 in size, while the whorls of the succeeding turns increase exceedingly 

 rapidly in width. Immediately after the nepionic whorls the upper surface 

 of the whorls becomes marked by numerous, closely crowded incremental 

 lines, which appear as slender threads under the microscope and in addi- 

 tion to this by very numerous very fine raised threads, the combination 

 of the two forming a clothlike texture. On the last quarter of the last 

 turn the spiral element becomes evanescent. The spiral sculpture is not 

 at all apparent to the naked eye on any part of the upper surface. Peri- 

 phery of the last whorl with a well rounded angle. Base marked by nu- 

 merous incremental threads, but without microscopic spiral sculpture. 

 Aperture, considering the outlines of the lips only, broadly oval, the outer 

 lip projecting as a broad clawlike element, while the inner lip is evenly 

 curved and very slightly reflected. If one looks at the shell absolutely 

 vertically the twist of the columellar edge appears as a slight perforation 

 that extends to the apex of the shell; parietal wall glazed with a thin callus. 



The type and another specimen, Cat. No. 219,050, U. S. N. M., were 

 collected by Mr. Weber at AJfonzo XIII, Palawan. The type has 4.1 

 whorls and measures: altitude, 7.1 mm.; greater diameter, 27.6 mm.; 

 lesser diameter, 18.6 mm. 



The National Museum collection contains this species from two other 

 localities; namely, Cat. No. 243,278b, U. S. N. M.,Pasig Beach, Manila, 

 and Cat. No. 240,292, U. S. N. M., Port Carlton, Busuanga. It is possible 

 that this is the shell which has been passing under the name of Turricula 

 planulata Recluz, which is an entirely different species, having its home 

 in the Seychelle Islands.
