robust than D. collarifera S. and B. or D. okiensis V. and H. It 

 further differs by having the parietal callus extended nearly to the 

 suture, and the palatal phca lies wholly or almost wholly under the 

 parietal callus. 



Eulota (Euhadra) contraria n. sp. 



The shell is depressed, biconvex, umbilicate, angular at the periphery, 

 thin, greenish-yellow with a narrow dark red-brown band on the 

 peripheral angle and narrowly visible above the suture on the last 1^ 

 whorls; inner whorls suffused with reddish-brown. Surface but 

 slightly shining. First If whorls, forming the embryonic shell, are 

 convex, with a close sculpture of low granules arranged in obliquely 

 descending series. The next H whorls have weak growth-lines and 

 minute, rather closely arranged papillae scarcely noticeable in some 

 specimens. The last two whorls have irregular growth-lines, and some 

 shallow, irregular spiral sulci, most obvious on the base; there are also 

 minute papillse visible in places. Whorls 5^, the first H convex, 

 the rest convex below the suture, then flattened. The last whorl 

 scarcely descends in front, and is convex below. The aperture is 

 oblique, wide, lunate. Peristome white, the upper margin expanded, 

 the outer and basal margins rather narrowly reflexed. The parietal 

 callus is extremely thin.

 1581 of Mr. Hirase's collection. 



This is a species of the E. succincta group. E. formosensis differs 

 by being more elevated , with the lip sinuous above and in having very 

 minute spiral striation on the last whorl. E. succincta is more com- 

 pact, with the last whorl narrower (viewed from above), and the 

 umbilicus is much smaller. The sculpture also differs in various 

 details. 



A specimen of E. contraria a little less mature than the type has the 

 last whorl reddish-brown, the spire paler. It is banded like the type 

 specimen. Only 10 examples of this fine snail were taken. 



Eulota (Euhadra) picta n. sp. 



The shell is rather narrowly umbilicate, somewhat depressed, with 

 conic spire; rather solid; pale yellow, with two broad dark reddish- 

 brown bands, the upper band extending from just below the periphery 

 half way to the suture, and ascending the spire above the suture, the 

 last 2 or 2^ whorls are therefore bicolored above; on earlier whorls the
