88 AURICULELLA, OAHU. 



Sa. A. ambusta obliqua Ancey. PL 23, figs. 3, 4. 



No formal description of A. obliqua has been published, but 

 Mr. Ancey has given the following notes: "Mr. Baldwin has 

 made the remark that there are in Oahu two species not in- 

 habiting the same districts, both called by the name auricula 

 Ferussac. I therefore propose the new name of obliqua for 

 those that are almost always sinistral, of a uniform white or 

 yellowish color, having the spire quite short, but chiefly re- 

 markable for the great obliquity of its strongly thickened 

 peristome, angular in the middle, and having a characteristic 

 sinuosity at this point. The base of the aperture recedes 

 strongly, and the peristome is very patulous at the lower ex- 

 tremity" (Ancey). 



Oahu, in the Waianae range: Lihue (Gulick) ; Western 

 ridge of Popouwela, abundant (Spalding, Cooke & Pilsbry) ; 

 Mokuleia (Gulick). 



Ancey 's type has been figured by Mr. Sykes, and is now- 

 contained in the Bishop Museum at Honolulu, and some of 

 the same lot, from Mr. Baldwin, are in coll. A. N. S. P. It 

 is white or straw-yellow, usually with some short cinnamon 

 streaks, faint or distinct, on the flattened periphery of the 

 last half whorl. In some of the specimens from. Lihue (fig. 

 4) these streaks are quite conspicuous. In others from Po- 

 pouwela they are frequently wanting altogether; but none in 

 a series of several hundred has any of the dull blackish epi- 

 dermis characteristic of A. ambusta. This, and the slightly 

 more lengthened shape are the sole peculiarities distinguish- 

 ing the subspecies from A. ambusta. The same form had been 

 named by Gulick, but his name never appeared in print, to 

 our knowledge. 



9. A. MALLEATA Ancey. PI. 27, figs. 12, 13, 14. 



'The shell is solid, perforate, oblong couoidal, glossy, 

 opaque, white, usually with a reddish or brownish, sometimes 

 white, apex; sinistral; under a lens subimpressed with light 

 lines of growth. Spire somewhat elongate, convexly con- 

 oidal, apex minute, somewhat acute. Whorls 6y 2 to 7, the 

 first slightly convex, the rest flat, very often malleate with a
