NEW LAND MOLLUSKS OF THE JAPANESE EMPIRE. 

 BY HENRY A. PILSBRY. 



Eulota (Plectotropis) shikokuensis n- sp. 



Shell openly umbilicate. rather thin, reddish-brown, low-conic 

 above, convex beneath, irregularly striate, and covered with short, 

 triangular cuticular scales, a series of longer ones along the per- 

 iphery. Whorls 5|^ to 6, slightly convex, the last carinated at the 

 periphery, more or less deflexed in front. Aperture very oblique, 

 subcircular, the peristome narrowly reflesed, dilated at the colu- 

 mella, the ends approaching. 



Alt. 8, diam. 14 mm. 



Alt. 7, diam. 12^ mm. 



Yoshida, Prov. lyo. Type No. 81885, Coll. A. K S. P., from 

 No. 694 of Mr. Hirase's collection. 



Similar in contour to trochula, of Tsu-shima. The cuticular 

 scales are less densely crowded than in scepasma. 



Eulota mercatoria var. daemonorum nov. 



Shell solid, with well-elevated spire and rounded periphery, 

 slightly plicatulate above, as in mercaforla, from which it differs in 

 the straighter, slightly bent forward, basal lip, with an impressed 

 line or two behind it, as in E. cuHginosa. 



Alt. 27, diam. 36 mm. ; whorls Qj^. 



Alt. 20^, diam. 29 mm. ; whorls 5f . 



Kikai, Osumi (Mr. Y. Ilirase, No. 683 ). It occurs fossil with 

 a form of Eulota liihuana, a large form of E. sieholdiana, 

 Cyclophorus turgidus, and fragments of a Clausilla, in a calcareous 

 deposit consisting largely of foramiuifera. 



Eulota (Plectotropis) omiensis n. sp. 



Shell small, openly umbilicate, low-conic above, convex beneath, 

 carinate at the periphery, brown. Surface of the last whorl 

 shaggy with triangular cuticular scales, large for so small a shell, 

 and longer at the periphery. Whorls 4^, convex, those of the 

 spire roughly striate, the last slightly and slowly descending in 

 85
