Fossils from the Upper Musashino of Kazusa and Shiuiosa. 91' 



reflexed outward. Height 6.5 millim. Diameter 2 millini. There 

 is also a specimen which measures 3 milhm. in diameter, but lack- 

 ing a greater part of tlie spire. 



This species is not unlike Evllma glabra Jeffreys (Try on, Man. 

 Concli., VIII, pi. 69, fig. 61), a form living in the Atlantic. But 

 the shape of the aperture is different. 



Fossil occurrence. — Shito (rare).

Shell very small, pyramidal. Apex obtuse, with the upper 

 part of the spire somewhat curved. Whorls six, nearly flat, 

 smooth, with sutures more or less indistinct. Body-whorl a httle 

 higher than half the shell-height. Periphery sharply rounded. 

 Aperture ovate, posteriorly pointed, anteriorly somewhat produced 

 and bluntly pointed. A single example present measures 1.7 

 millim. in height and 0.6 millim. in diameter. 



This shell looks like Eulima yokoskensis Yok. (Foss. Miura 

 Penin. , p. 79, pi. V, fig. 7) from Yokosuka, but is smaller and less 



acute.
