62 THE NAUTILUS. 



mandarina is quite variable. The figured type measures alt. 17, diam. 

 21 mm. Three specimens from Tane-ga-shima (from no. 660 of Mr. 

 Hirase's collection) measure 16x2H, 18x244 and 20x26 mm. They 

 are reddish-brown, with a narrow dark band at the periphery. Two 

 others from the same island are more elevated, measuring alt. 22, 

 diam. 21, and alt. 21, diam. 25 mm. ; the latter being of a rich dark 

 chestnut color, the band black. These are Mr. Hirase's no. 659. 



From Yaku-shima the shells sent out are larger, alt. 23, diam. 30; 

 alt. 22, diam. 28 mm. They have 6^ whorls, like the smaller shells 

 of Tane-ga shima, and the color is rather light, the peripheral band 

 reduced to an indistinct line. This form I have called var. magna. 

 It is no. 672 of Mr. Hirase's collection. 



Doubtless E. submandarina is peculiar to these and perhaps some 

 neighbor ing islands. 



The following species are not confined to the two islands : Trocho- 

 morpha Gouldiana Pils. occurs on Yaku-shima, indistinguishable from 

 the types from Oshima. Macrochlamys tanegashimce has recently been 

 received from Kago-shima, Satsuma (Mr. Hirase's no. 701), quite 

 like the types, but slightly larger. Sitala circumcincta var. data 

 (Gude) is a trifle more brown in color than the types from Hondo, 

 the perforation is perceptibly wider, and the whorls possibly less con- 

 vex ; but specimens received from three localities in Kiusiu are 

 partly similar, partly intermediate in characters, so that although it 

 takes next to no difference to make a '' species " in this group, I do 

 not think the Kiusiu or Yaku-shima Sitalas deserve separation from 

 the Nippon form. 



Among the land operculates there is a new Spiropoma ( Ccelopoma) 

 which has been called S. Nakadai, and a new PupineUa, P. Fimatoi. 

 These are named for Messrs. Nakada and Funato, two able and en- 

 thusiastic collectors of shells for Mr. Hirase. 



The ClausiliidcR are represented by five species and several vari- 

 eties, all peculiar to the islands, and remarkable for the excessive 

 thickness of the shells. Their general relations are with species of 

 Kiusiu and Nippon, not with those of the central group of the Loo 

 Choo Is. The wonderful forms with plicate lips, found in Oshima 

 and Great Luchu (Okinawa or Nawa Island) are apparently wanting 

 in Tane-ga-shima and Yaku-shima, and their place is taken by 

 species of the sections Stereophcadusa and Hemiphcedusa. All but 

 Clausilia stereoma are rather small, and all of them are remarkably
