short of corresponding with the position of the peristome; another 

 on line with it is upon the preceding whorl; the next earlier whorl 

 has a varix-line near its beginning, almost a whorl being thus with- 

 out a varix. A young shell, 6 ram. long, has one varix-line on 

 the back of the penultimate whorl. E. philippiana measures, alt. 

 10.2, diam. 2.15, longest axis of aperture 2.67 inm. Dunker gives 

 alt. 11, diam. 2 mm. for the type. 



Evidently, these species have resting stages at irregular intervals, 

 and the varix-lines are inconstant in position and number. 



Both of these species are remarkable for the thickness of the 

 upper part of the spire, though this feature is more exaggerated in 

 E. dunkeriana. 



Eulima luchuana n. sp. PL XXI, fig. 23. 



Shell white and glossy, conic, curved slightly to the right, that 

 margin being about straight while the left side is a little convex, 

 regularly tapering, 9^ whorls remaining (the apex being decollate), 

 slightly convex, the penultimate whorl having an impressed varix- 

 line at its last sixth, the preceding whorl with one on line with 

 the peristome, the next earlier whorl with a varix-line correspond- 

 ing in position to that on the penultimate whorl; the varices thus 

 being all on the right or incurved side. Aperture ovate-acuminate, 

 the lip a little obtuse. 



Alt. 12, diam. 3.85, longest axis of aperture 4.15 mm. 



Loo Choo Islands (Mr. Y. Hirase). Types No. 80,628 Coll. 

 A. N. S. P., from No. 1,275 of Mr. Hirase's collection. 



The aperture is longer than in E. nitidula A. Ad., which, 

 though a smaller species, is described as having 11 whorls. 



Assiminea angustata n. sp. 



Shell minute, imperforate, or nearly so, long ovate-conic, solid, 

 red-brown, glossy and smooth. Whorls about 5J, rather flattened, 

 the last one convex. Aperture small, rounded-ovate, oblique; 

 peristome simple, the columellar and parietal margins somewhat 

 thickened. Length 3, diam. 1.7, longest axis of aperture 1.2 mm. 



Rishiri, Kitami (Mr. Y. Hirase, No. 1,277 of marine mollusk 

 list). 



Unusually lengthened for Assiminea, but with the color and 

 texture of that genus, though it may possibly be Rissoid.
