THE NAUTILUS. 3 



This attractive shell is much like a reversed P. (^Anliplnnes) 

 santnrosana Dull, in color and sculpture, but the whorls are more 

 oblique besides being reversed, and the spire is even more slender 

 than in Dall's species. P. {Antiplanes) catalinae was found associa- 

 ted with P. {Antiplanes) perversa Gabb, which is also sinistral. 

 The latter species is wider, has less rounded whorls and the color is 

 a darker brown with a light, spiral band, as stated by Gabb in his 

 original description. Tiie two species are readily separated. 



DESCKIPTIONS OF NEW JAPANESE LAND SHELLS. 



BY H. A. PILSBRY AND Y. HIRASE. 



Eulota { Plecfotropis) pannosa var. awashimaiia n. var. 



This race is similar to JS. pannosa in color, texture, sculpture and 

 the profuse peripheral fringe, but differs in being much smaller, pro- 

 portionally higher, with decidedly narrower umbilicus, which is not 

 enlarged at the opening, the base being almost angular around it. 

 Whorls 5^, the last very shortly and slightly deflexed in front. It 

 is more robust and less depressed than E. deflexn. Alt. 8, diam. 

 13 mm. 



Awashima, Ecliigo. Types no. 86495, A. N. S. P., from no. 

 1164 of Mr. Hirase's collection. 



Two species of Plectotropis have been described by A. Adams 

 from Awashima : H. setocincta and H. scahricula. The first meas- 

 ures about 12x6 mm., the altitude half the diameter, being therefore 

 more depressed than awashlmana, in which the alt. is nearly two- 

 thirds the diam. H. scabricida is about 9x6 mm., with G^ whorls, 

 the last " subangulate " peripherally. This species is therefore 

 smaller than aicasMinana, with more whorls and blunter ambitus. 



Helix conella A. Ad., 1868. from "Tabu-Sima" (not H. conella 

 Pfr., 1861), is probably a synonym of Plectotropis dejiexa Pfr., from 

 the same island. 



Eulota {Plectotropis) shikokuensis subdivesta n. subsp. 



Sjiell more depressed than E. shikokuensis, and smoother, the 

 oblong granules bearing no cuticular scales, the periphery without a 

 fringe. Whorls nearly 6, the last very shortly and abruptly de-
