Hab. Oahu, Sandwich Islands. 



Distinguished from A.pkta, to which it is the nearest 

 allied species, by its more elongated form and bi'ight 

 yellow ground-colouring. 



Species 33. (Mus. Cuming.)

 sbihtrorsd, spird siibncuminatd, anfractibus rotimdaiiK,

The citron Achatinella. Shell elongately conical, 

 sinistral, spire somewhat acuminated, whorls roimded, 

 finely striated, the last finely obsoletely keeled, colu- 

 mella much twisted, two-plaited, aperture rather 

 small ; bright citron yellow. 



MiGHELS, MS. 



Hab. Sandwich Islands. 



This has all the appearance of an unspotted variety of 

 the preceding species, but it will be found to diflfcr in 

 form upon a careful comparison. It does not agree with 

 Ferussac's figure, Hist. Moll. pi. 155. f. 12. HeU.x (Coch- 

 logena) luteola, representing an immature shell which I 

 have not been able correctly to identify. 



Species 34. (Fig. 34 and 41. Mus. Cuming.) 

 Achatinella turritella. Achat, testd elongato-conicd, 

 subpyramidali, anfractibus septeni, planiconvexis, ob- 

 lique rude striatis, ad suturas subcremdatis, aperturd 

 parvd, columelld biplicatd, appressd; intense castaned, 

 fascld albidd infra suturas. 



The little turret Achatinella. Shell elongately 

 conical, somewhat pyramidal, whorls seven in num- 

 ber, flatly convex, obliquely rudely striated, slightly 

 crenulated at the sutures, aperture small, columella 

 two-plaited, appressed ; dark chestnut, with a whitish 

 band beneath the sutures. 



Ferussac, Hist. Moll. pi. 155. f. 13. 

 Achatinella Oahuensis, Green. 

 Achatinella inoruata, Mighels. 



Hab. Oahu, Sandwich Islands. 



This species represents the most elongately turreted 

 form of the genus. 



Species 35. (Mus. Cuming.) 



Achatinella radiata. Achat, testd ovatd, soliduld, 

 dextrorsd, anfractibus convexis, oblique striatis, superne 

 subobscure marginatis, columelld brevi, plicato-contortd, 

 late appressd, labro subincrassato ; luteo-albidd, strigis 

 Uneisque intense viridibus et nigrh densissime oblique 

 pictd, columelld labroque carneo-rosaceis.

 painted with dark green and black streaks and lines, 

 lip and columella flesh-pink. 



Pfeiffer, Pro. Zool. Soc. 1845, p. 80. 



Hab. Oahu, Sandwich Islands. 



A very characteristic richly painted species, quite dis- 

 tinct from A. firidans. 



Species 36. (Mus. Cuming.) 



Achatinella picta. Achat, testd acmniiiato-ovatd, sinis- 

 trorsd, anfractibus rotundatis, tumidiusculis, columelld
