188 ACHATESTELLA BUDDII. 



In shape A. buddii does not differ materially from the wid- 

 est specimens of A. fulgens. The apex is dark. The colu- 

 mellar fold is often smaller and generally vinaceous. 

 The chief difference is one of color; in buddii the shell 

 in its more primitive pattern is closely streaked with liver 

 brown to purplish vinaceous, flesh color and whitish or creamy, 

 or with flesh-tint or yellowish brown alone, on a paler ground, 

 the sutural margin self-colored or narrowly white. The 

 streaks are sometimes continuous, but usually the pattern is 

 varied by darker or lighter spiral zones, or interrupted by 

 white bands or zones, and there are occasional albino in- 

 dividuals. Through various stages, there is a passage to the 

 banded pattern, in which there are spiral bands and lines of 

 chestnut brown or blackish brown on a white or buff ground, 

 often shading towards the base to cream-buff, sometimes 

 streaked with brown. Often there is a very faint brownish 

 line below the suture, and in the rare mutation described as 

 A. fuscozona, there is a subsutural chestnut band. The em- 

 bryonic shell is often brown with a wide white or pale zone 

 below the suture ; and when white it always has a dark tip, 

 even in albinos. In A. fulgens the embryo is white as a rule, 

 but sometimes it has a dark tip. Specimens of buddii from 

 Waialae, Palolo, pi. 36, f. 7 to le, and Makiki, pi. 36, f. 8, 8a, 

 do not differ materially. 



A. buddii was formerly not uncommon in Palolo, where 

 large numbers were collected by Newcomb, Gulick and doubt- 

 less many others. The supposed A. fuscozona recorded by 

 Messrs. Gulick and Smith from Palolo have no direct connec- 

 tion with the fuscozona of Makiki, but are an independent 

 though somewhat similar form of buddii. There is a very 

 pale sutural band of a light ochraceous-buff tint, on a straw 

 yellow or nearly white ground, and the apex is that of typical 

 buddii. The specimens are no. 678 of Gulick 's collection, 

 and no doubt were selected out of his Palolo lot of buddii. 



About 1855 Mr. J. S. Emerson collected an ample series 

 in the bottom of Manoa valley on the Sugar Loaf side, above 

 where Dr. Cooke's house now stands, in a grove of kukui 

 trees then being cut by Chinese to obtain pepeitao-laau, an
