DESCRIPTIONS OF NEW KOREAN LAND SHELLS 



By H. A. PILSBRV and Y. HIRASE 

 (With PL. V) 



Recent collections have materially increased our knowledge of 

 Korean mollusks. The localities Fusan, Mokpo and Kojeto, an 

 island close to the coast, have each supplied several species. The 

 following descriptions are preliminary to a catalogue of Korean land 

 shells, now in preparation. 



Alycaeus cyclophoroides n. sp. pi. v, figs. 1, 2. 



The shell is similar in general appearance to Japanese and 

 Chinese species of the subgenus Chamalycmis ; pale reddish brown, 

 or tinted with that color at the apex and on the swelling of the last 

 whorl, elsewhere whitish. Whorls 3J4, the first 1*4 smooth, then 

 delicate, close riblets begin. On the moderately swollen third of the 

 last whorl the riblets become a little closer and continue so to the 

 peristome. The reflexed sutural " tube " is rather long. The neck 

 is moderately contracted, then enlarges a little. The aperture is very 

 oblique, circular. The peristome is very broadly expanded and 

 reflexed, its face being convex, and the edge a little rolled back. 

 The umbilicus is elliptical.

Fusan, Korea. Cotypes no. 95,741 Acad. Nat. Sci. Phila. and 

 no. 1,520 of Hirase's collection. 



This species is chiefly remarkable for its broad peristome, which 

 is rolled back as in many of the larger species of Cyclopliorits. It is 

 related to A. tsushimanus, but that species differs by having a distinct 

 swelling between the contraction of the neck and the peristome. 



Eulota (^gista) proxima n. sp. pi. v, figs. 3, 4. 



This shell closely resembles E. friedeliana of Kyushu, being 

 openly umbilicate, with a low, conic spire and obtuse, subangular,
