THE NAUTILUS. 1 15 



Shikoku, witli Mr. Adzama. We hope to liave still more good things 

 from this prolific province. 



Mr. Hatai, who assisted Mr. Nakada in Ogasawara (Bonin Islands), 

 continued to collect there after Mr. Nakada's return. On September 

 25tli he started from Chichijima to go to Yuo-jima, small islands 

 soutlivvard from the Ogasawara group. He reached Kita- Yuo-jima 

 safely, but owing to stormy weather, a landing on Naka-Yuo-jima 

 could not be made. The vessel stayed at sea, but the storm in- 

 creased, and the ship was lost. After more than eighty days, no 

 tidings of him have come. Mr. Hatai was faithful to the work, and 

 his untimely loss tlirough his efforts to increase our knowledge of 

 these island faunas is deeply felt. 



Eulota {Euhadra) sadoensis P. & H., n. sp. 



Shell rather narrowly umbilicate, somewhat trochoidal, buff- 

 whitish, with a sharply-defined dark chestnut band just above the 

 periphery, a wider one, fading at the edges, on the upper surface, and 

 a very broad band extending over most of the base, the interior of 

 the umbilicus also dark ; these bands leave the pale ground-color in 

 narrow belts below the suture, above and below the periphery, and 

 around the umbilicus. Surface glossy, irregularly obliquely striate, 

 and showing the nsual very fine spiral lines. Spire elevated, conic, 

 the apex obtuse. Whorls 5^, moderately convex, the last depressed 

 but not angular, very slightly descending in front. Aperture very 

 oblique, somewhat lunate ; peristome expanded and reflexed, dilated 

 half over the umbilicus, white, except where colored by the bands. 

 Alt. 17, diam. 24 mm. 



Sotokaifu-mura, Sado. Type no. 83909 A. N. S. P., from no. 

 994 of Mr. Hirase's collection. 



This seems quite distinct from other members of the peb'omphala 

 group of Helices. The coloration reminds one of Epiphragmophora 

 mornionum var. cala. 



Eulota (Plectotropis) kiusitiensis var. oshimana n. var. 



Similar to E. khismeiisi's in texture, sculpture, umbilicus and per- 

 ipheral keel ; but the spire is higher, and the color chestnut-brown 

 instead of yellowish. 



Oshima, Osumi. Types no. 83891 A. N. S. P., from no. 914 of 

 Mr. Hirase's collection.
