136 THE NAUTILUS. 



Sodayama, Tosa. Types no. 84412. A. N, 8. P., from no. 1016 

 of Mr. Hinise's collection. 



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

 Hilizan on the western side of Lake Biwa, etc. It varies from 

 reddish-brown to nearly as pale as T. goodwini. Tlie variety from 

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

 'The types are variegated as described above. A series from Koclii, 

 Tosa (Mr. Hi rase 's no. 580), has neither the pale peripheral band 

 nor the streaks of the shells from Sodayama, and varies from pale 

 brown to nearly as light a tint as T. goodwini. Specimens of this 

 lot were compared by Mr. Glide 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), 

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



Arinia jitponica n. sp. 



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

 extremely short, low brownislt cone of hardly two whorls. Surface 

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

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

 very widely spaced. Whorls o^, convex, the last whorl distorted, 

 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 thickened 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 6f its kind. It is remarkable ior the very obtuse 

 summit. 



ILLUSTRATIONS OF SOME JAPANESE LAND SHELLS. 



Several of the Japanese 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.
