TOO AURICULELLA, OAHU. 



westerlundiana Ancey. It differs from the first, which comes 

 from a different part of Oahu, by the smaller size, the larger 

 number of whorls, its color, etc. It differs, likewise, from the 

 ^second by its color, the larger number of whorls, especially 

 by the shell being more slender, glossy, and other characters 

 which a comparison of the descriptions sufficiently shows. A. 

 <obeliscus of Pfeiffer is closely related to tenella ; they agree in 

 the number of whorls, columella, and proportions; it differs 

 in color, in its sharp apex, its simple suture, etc." (Ancey). 



This is a rather rare species and one that is not found in 

 many collections. I have collected a few specimens at Pale- 

 liua, near the southeastern end of the Waianae Mts., and an- 

 other small series back of Leilehua, at about the middle of 

 the range ; these two series agree very closely and present only 

 very slight differences. It is abundant on the western ridge 

 -of Popouwela. I have only three color- varieties of this species 

 in addition to the typical pattern (fig. 7) ; the first uniformly 

 corneous; the second corneous with broad light chestnut 

 .streaks; the third a slightly darker shade of chestnut, with a 

 narrow dark chestnut band at the periphery extending on the 

 .spire, and almost covered by the suture. Fig. 8 represents a 

 whitish corneous specimen with cinnamon streaks and a chest- 

 nut brown band. It measures, length 6.5, oblique diam. 3 

 mm. 



There is a rather small circular umbilicus, decidedly larger 

 than in A. tantalus. 



21. A. KUESTERI (Pfeiffer). Not figured. 



Shell subperforate, ovate-turrite, rather solid, very lightly 

 ^striate, subopaque, pale green. Spire regularly long-conic, 

 the apex rather obtuse; suture linear, margined. Whorls 6, 

 nearly flat, the last slightly exceeding two-fifths the total 

 length, rounded at base. Aperture oblique, semioval, with a 

 compressed, oblique deeply-entering parietal lamella; colu- 

 mella acutely toothed ; peristome simple, acute, the columellar 

 margin reflexed. Length 8, diam. 4; aperture 3.33 mm. (Pfr.) 



Habitat unknown ; described from the Cuming collection.
