FUIvGENS GROUP. 

 45. Achatinella fulgens Newcomb. 



A.fuigens Newc. P. Zool. Soc. London, 1S53, p. 131, pi. xxii, fig. 24, 24a. 



Shell elongately conic, polished, shining ; whorls 6, flatly con- 

 vex ; suture slightly impressed ; aperture ovate ; columella short, 

 tuberculated; lip simple, ribbed within; colour rich chestnut-brown, 

 with a broad white sutural fascia cutting the centre of the last 

 whorl ; apex and columella white. lyong. 18/20, lat. 8/20 poll. 



Var. A. White, with broad chestnut bands. 



Var. B. Chestnut-coloured above, yellowish below, with two 

 black and one white band, the columella dark brown ; of large 

 size, measuring 22-20X 10-20 of an inch. 



This last variety may, upon further examination, prove to be 

 a distinct species. The locality of this last is Makiki Valley, 

 "Mauka roa," or far back in the mountain range. An examina- 

 tion of the respecftive animals will resolve the doubt. — Newc. 



Hab. Niu. — Newc. 



This and the following seven species are very nearly related, 

 and form a very interesting group. They are all found in the dis- 

 trict between Niu Valley and Makiki ; all are sinistral, and the 

 great number of color varieties run one into the other. Over one 

 thousand examples of this varied group are in the author's colledlion. 



46. Achatinella buddii Newcomb. 



A. buddiiTSewc. P. Zool. Soc. London, 1S53, p. 155; pi. xxiv, fig. 73. 



Shell sinistral, conically ovate, solid ; whorls 6, convex,
