HELIX-EUHADRA. 123 



from the Swift collection, marked " Loo-Choo Is." The last local- 

 ity is probably correct. Both specimens were in trays containing 

 H. mandarina. 



H. CALIGIXOSA Adams & Reeve. PI. 27, figs. 9, 10, lOa. 



Shell globose depressed with couoidal spire, the umbilicus narrow 

 but deep, circular, and somewhat impinged upon by the reflexed 

 columella ; rather thin but solid ; color fawn-brown, encircled by a 

 narrow red band, the upper whorls yellowish-white. Surface sculpt- 

 ured by close, oblique arcuate striae, conspicuous both above and 

 below, the whorls of the spire showing under a strong lens minute, 

 delicate separated granules or little elevated points. Spire rather 

 elevated, apex minute, shining, whitish ; sutures well impressed 

 from the apex to its termination. Whorls 6?, convex, slowly widen- 

 ing, the last slightly descending in front. Aperture oblique, lunate ; 

 peristome expanded, the basal margin sinuous (being arched forward, 

 seen from below), the columellar margin suddenly dilated and 

 partially covering the umbilicus. 



Alt. 25, greater diam. 32, lesser 29 mill.

This species is said by Reeve to belong to the group of which 

 H. ungulina is the type. The only published figures represent base 

 and top views, so I am not absolutely certain that the specimen 

 before me (from which fig. 10 of pi. 27 was drawn) is correctly 

 named. The original description is as follows : " Shell subglobose, 

 perforate, concentrically marked by oblique, slightly elevated 

 streaks, yellowish-white ; whorls 6, the last spadiceous-brown, sur- 

 rounded by a narrow rufous band ; aperture depressed-lunate, peris- 

 tome reflexed." 



The specimen drawn in fig. 10 probably a little abnormally 

 elevated. 



H. PHILIPPINENSIS Semper. PI. 60, figs. 1, 2, 3, 4. 



Shell large, depressed, very solid and strong, narrowly umbilicated, 

 opaque, of a beautiful reddish-fawn color, somewhat darker on the 

 spire, and encircled just above the periphery by an indistinct darker 

 band. The surface is nearly lusterless, nearly smooth below, oblique, 

 rather coarsely striate above. Spire low, depressed ; suture im- 

 pressed ; whorls 5 J, slightly convex, the last very obsoletely angulated
