Diplommatina paxillus (Gredler). 



Cheju. The specimens agree well with Chinese examples 

 received from the late Mr. B. Schmacker. It occurs also at Mokpo, 

 Korea. 



Alycaeus kurodai n. sp. (PI. 1\", figs, i — 4). 



The shell is quite depressed, widely umbilicate, the umbilicus 

 about one-third the total diameter of the shell ; spire low, convex, 

 the apex projecting; pale reddish brown. Whorls 3? 4 , the first 1 ' ■ 

 smooth, red or brown, the rest very delicately, closely striate. The 

 last half of the last whorl is moderately inflated, the stria.- becoming 

 stronger and less closely spaced on the latter part of the inflation. 

 The neck is short, rather strongly contracted, then encircled with a 

 strong rounded ridge, which is less oblique than the peristome, and 

 close behind it. The aperture is circular, quite oblique. The 

 peristome is thin, broadly expanded and recurved at the edge, the 

 face convex. It is narrower on the columellar margin, and is 

 adnate to the whorl for a short distance. 



Alt. 2.8, diam. 4.8 mm. 



The operculum lodges in a vertical position just inside the aper- 

 ture, and is of a yellowish olive-brown color. The central part 

 (about one-third the total diameter) is smooth and sunken ; the last 

 four whorls have oblique growth-lines and are elevated into a 

 lamella at the sutures. There seem to be 6 or 7 whorls in all. 



Cheju (Ouelpart) Island. Cotypes No. 95,742 Acad. Nat. Sci. 

 Philadelphia, and No. 1,537 of Mr. Hirase's collection. 



This species is very distinct by its short neck with a strong 

 rounded ridge behind the peristome. It is quite unlike any of the 

 Japanese species. It is named in honor of Mr. Tokubei Kuroda, to 

 whom we owe the first collection from Ouelpait.

Eulota (Euhadra) orientalis (Adams & Reeve). 



Cheju. Typical specimens of this fine species. 



Trishoplita dacostas awajiensis Tils. 



The specimens seem quite indistinguishable from the Awaji 

 Island form, notwithstanding the wide separation of the two islands. 

 It occurs also at Fusan, Korea.
