I~Z8 THE NAUTILUS. 



H. verecunda is cream-white with reddish streaks, or red with or 



without whitish streaks; the color " luteo-virens " described by Gould 

 being due to the dried animal which shows through in places with a 

 dark green tint. The half dozen specimens of H. osumiensis before 

 me are uniform red. 



Mr. Y. Hi rase has distributed H. verecunda as No. 470, from Loo 

 Choo (Riu Kiu, or Ryu Kyu). The specimens agree with one of 

 Gould's original lot, in the collection of the Academy. I suppose 

 they are from Okinawa Island. So far, we know scarcely anything 

 of the snail fauna of the other islands of the group. Recent sub- 

 sidence and breaking up into islands, of a ridge running from 

 Okinawa to Kiusiu is suggested by the close alliance of the southern 

 Kiusiu and Loo Choo faunas. 



The Helicina hakodadiensis of Hartman (1890) has been rediscov- 

 ered by Mr. Hi rase at Kayabe, Ojima, Hokkaido Id. (No. 595). It 

 is quite a distinct species, more angular at the periphery than other 

 Japanese forms, and with the ruddy color of H. osumiensis and the 

 American H. occulta. H hakodadiensis is, next to the last-named 

 species, the northernmost of its genus, its locality lying in about 42° 

 N. Lat., while occulta extends to about 44° N. 



Helicina Reinii var. tizenensis n. var. Shell differing from H reinii 

 Kobelt in being larger, pink or whitish-pink under a yellowish 

 chestnut-colored cuticle, which remains in shreds and streaks only, 

 and in the closely and deeply striated surface. Alt. 12, diam. 15 to 

 16 mm. Nishigo, Uzen. 



Vertigo Hirasei n. sp. A minute, ovate, glossy-brown species 

 with 4^ whorls, the aperture having a parietal and a columellar 

 lamella, and two palatal folds, the lower larger, elongate, the upper 

 tuberculiform, sometimes obsolete. Alt. 1.5, diam. 1 mm. Yana- 

 gawa, prov. Chikugo, Kiusiu Id. (Mr. Ilirase, No. 570). 



Bidiminus callistoderma var. oyasawarce n. v. Similar to callisto- 

 derma in texture, sculpture and color, but distinctly longer, with 7 

 whorls, the spire perceptibly attenuated below the thick, obtuse 

 apex. Length 13, diam. 5^, length of aperture 5 mm.; length 12^, 

 diam. 5A, aperture 5^ mill. Ogasawara or Bonin Is. (Mr. Y. 

 Hirase, No. 602). 



Buliminui eucharistus n. sp. Shell rimate, high-conic, solid, 

 purplish-brown, closely streaked with whitish or yellow. Spire 

 straightly conic, the apex obtuse ; whorls 8^-9, moderately convex,
