176. Achatinella germana Newcomb. 



A. gevmana Newc. P. Zool. Soc. London, 1853, p. 151, pi. xxiv, fig. 61. 



Shell dextral, ovately conical; whorls 6, flatly convex; aper- 

 ture ovate ; lip acute, thickened within; columella brown, short 

 and tubercular ; colour chestnut, with fine obsolete darker trans- 

 verse lines ; a white band traverses the last sutural whorl and cuts 

 the body whorl centrally ; around the columella is a broad white 

 baud, losing itself in the aperture. Long. 16/20, lat. 8/20 poll. 



Closely resembles the A. solitaria, and but for the widely dis- 

 tant localities, might be taken for a variety of the same species. 

 The markings and columellse are, however, quite distinct. — Newc. 



Hab. Makawao. — Newc. 



Dr. Cooke found in the type shell the apex and first whorl to 

 be of a dark color, second whorl of a slate color, third whorl of a 

 slate brown, and the fourth whorl brown.
