136 THE NAUTILUS. 



Sodayama, Tosa. Types no. 84412. A. N. S. P., from no. 1016 

 •of Mr. Hirase's collection. 



T. mesogonia is from the province Tango in western Hondo, 

 Hilizan on the western side of Lake Biwa, etc. It varies fi-om 

 reddish-brown to nearly as pale as T. goodwlni. Tlu; variety from 

 Shikoku is similar in shape, but constantly different in sculpture. 

 The types are variegated as described above. A series fi-om Koclii, 

 Tosa (Mr. Hirase's no. 580), has neither the pale peri[)hera! band 

 jior the streaks of the shells from Sodayama, and varies from pale 

 Ibrown to nearly as light a tint as T. yoodwini. Specimens of this 

 lot were compareil by Mr. Gude with his T. goodwini var. carinata, 

 and said to " differ in the body-whorl, and the aperture is smaller 

 and more rounded." Others were found at Suimura, Awa (Shikoku), 

 JMr. Hirase's no. 823, like the Kochi lot. 



Arinia japonica n. sp. 



The shell is very minute, gray, cylindric, terminating above in an 

 extremely short., loio broionish cone of hardly two whorls. Surface 

 lusterless, sculptured with narrow ribs, like a Diplommatina. These 

 ribs are fine and ratlter close, but on the last whorl they become 

 i)ery widely spaced. Whorls 5^^, convex, the last whorl distoi'ted, 

 being smaller than the preceding whorl, and strongly ascending in 

 front. It is very shortly and inconspicuously rimate. The aperture 

 is vertical and circular. The peristome is continuous, very narrowly 

 expanded, and tliickened outside behind the edge. The columella is 

 simply concave. Length 2. diam. 1.2 mm. 



Goto, Hizen. Types no. 84413. A. N. S. P., from no. 1018 of 

 Mr. Hirase's collection. 



This tiny snail is the first Arinia from Japan, and by far the 

 most northern 5f its kind. It is remarkable ior the very obtuse 

 summit. 



ILLUSTRATIONS OF SOME JAPANESE LAND SHELLS. 



Several of the Jai)anese snails described in the Nautilus during 

 the past year or two are illustrated on the plate accompanying Mr. 

 Hirase's catalogue of Japanese shells inserted in our advertising 

 pages this month. As some of them have not before been figured, it 

 seems proper briefly to refer to them.
