 peripheral baud, bordered above and below with a narrow lighter 

 zone. Diam. maj. 32, min. 275 mm.; alt. 18 mm.

19. Vallonia tenera, Peinh. Osaka. Five specimens. 



LOO-CHOO ISLANDS. 

 20. Macrochlamys fulgens, n.sp. PL VIII, Figs. 24-26. 

 Shell perforate, trochoid, thin, shining, pellucid, dark corneous. 

 Spire depressed, apex obtuse, suture linear, margined. Whorls 4, 

 I increasing rather suddenly ; the last twice as wide as the penultimate, 

 L convex, a little inflated ; finely striated, decussated by microscopic 

 [spiral lines. Last whorl not descending, slightly excavated in the 

 "umbilical region. Aperture slightly oblique, lunate; peristome thin, 

 "straight, acute; margins distant, sub-parallel, the columellar margin 

 a little reflected and nearly covering the very narrow umbilical 

 perforation. Diam. maj. 7, min. 6 mm.; alt. 4*5 mm. 

 Ilab. — Loo-Choo Islands. 

 Type in my collection. Ten specimens. 

 ! This Macrochlamys is, I believe, the first recorded from the 

 Loo-Choo group. 



21. Arnouldia Nahaexsis, n.sp. PI. VIII, Pigs. 21-23. 



Shell imperforate, trochoid, thin, pellucid, pale corneous. Spire 

 i elevated, apex obtuse, suture impressed. Whorls 5£, widening very 

 slowly, convex, with a thread-like compressed keel at the periphery. 

 Last whorl scarcely wider than the penultimate, not descending in 

 , front, excavated in the umbilical region. Aperture a little oblique, 

 lunate ; peristome thin, acute, straight, margins distant, columellar 

 margin a little reflected. Diam. 3, alt. 2 -5 mm. 



H(dt.— Naha. 



Type in my collection. Ten specimens. 



This genus, like the preceding, has not, to my knowledge, been 

 hitherto found in the Loo-Choo Islands. Possibly many more species 

 of both genera remain to be discovered. The present Arnouldia 

 appears to be allied to A. pustulina, Peinh., a Japanese shell. 



22. Gaxesella tdrrita, n.sp. PL VIII, Pigs. 1 and 2. 

 Shell dextral, perforate, elongate-conoid, thin, sub-pellucid, pale 

 corneous, very finely obliquely striated, under a strong lens seen to be 

 decussated with microscopic wrinkled spiral lines. Spire elevated; 

 apex minute, exserted ; suture slightly impressed. Whorls 9, 

 increasing slowly, the first four a little rounded, the remaining 

 flattened above, a little swollen below, carinated at the periphery ; 

 the last not descending in front, the baBe swollen round the umbilicus, 

 a little flattened below the peripheral keel. Aperture oblique, semi- 

 ovate ; peristome thin, acute, a little reflected; the margins converging,
