300 PARTULA, NEW IRELAND, ETC. 



narrowly, deeply, umbilicate ; pale grayish yellow, but slightly 

 shining. Whorls 5, all moderately convex; 2% embryonic 

 whorls are sculptured with delicate punctate spiral lines as 

 usual ; following whorls have fine incised spiral lines through- 

 out, strongest on the last whorl. The suture is impressed, 

 and at its last turn is bordered 'above ; this border is narrow, 

 and continued as a slightly differentiated belt on the last 

 whorl, in front of the aperture. The last whorl is somewhat 

 compressed laterally and full at the base. The aperture is 

 slightly oblique, ovate, flesh-tinted inside ; lip white, narrowly 

 reflexed, thickened within except at the upper curve where it 

 is thin. Golumella dilated above. Length 14.8, diam. 8, 

 aperture 7.2 x 5 mm.

Partula kubaryi HARTM., Proc. A. N. S. Phila. 1890, p. 284, 

 pi. 3, f. 3 (Oct. 21, 1890). 



This species stands close to P. coxi, 'but it is larger, slightly 

 more solid, and more conic in shape, the last whorl being 

 broader. 



94. P. OBLITERATA PM)ry, n. sp. PI. 37, figs. 11, 12. 



The shell is ovate with conic spire ; shortly rimate and per- 

 forate; moderately 'strong; pale yellowish with indistinct 

 darker, slightly greenish yellow streaks, the apical whorls 

 faintly brown; somewhat glossy. Whorls 5, the embryonic 

 2y 2 puncture-striate, the rest marked with distinct, irregular 

 growth-wrinkles and faint spiral lines, weak and rather in- 

 distinct on the last whorl. Last whorl rather convex. Aper- 

 ture ovate, whitish within ; outer lip narrowly reflexed, white, 

 rather strongly thickened within except at the posterior curve 

 of the lip, at its other termination, on the columella, the end of 

 the callus is not noticeable. Length 16, diam. 9, aperture 

 8y 2 mm. 



New Ireland? 



This species stands near P. kubaryi, having almost the 

 same contour, but" it differs by the very weak spiral striation. 

 P. micans has a thinner lip and much more distinct sculpture. 

 This species is known to me by a set of three examples re-
