ACHATINELLA BUDDII. 189 



edible fungus. The shells are of the streaked and also the 

 banded patterns. These localities have long since been de- 

 forested, and the species is now to be found only high in 

 Makiki, where the banded pattern, pi. 36, fig. 8a, prevails. 

 A few specimens which had escaped shell collectors could still 

 be found hiding in knot holes and crevices in the bark of cer- 

 tain old kukui trees, when Doctor Cooke and I visited the 

 place in 1913. It seems to be a shell of the kukui zone, prob- 

 ably not found at greater elevations. 



An unusual pattern of buddii was selected to form the sup- 

 posed species fuscozona. The description follows, with notes 

 on the type and other specimens. It seems to be a mutation 

 which did not become general in occurrence. There are many 

 instances where a particular pattern has been found on a few 

 trees only. 



Color var. fuscozona Smith. PL 38, fig. 15. "Shell sinis- 

 tral, ovate-conic, perforate, slightly shining, striated with 

 growth lines and (under the lens) very minute transverse 

 lines; whitish, more or less streaked obliquely with light 

 brown, and transversely indistinctly lined and zoned; suture 

 distinctly margined with brown; whorls 6%, convex, the last 

 one ample ; apex blackish ; aperture white, peristome thin, 

 lightly bordered within; columellar fold strong, reddish 

 (sometimes whitish). Length 21, diam. 12 mm. 



" Var. Shell long-conic; suture girdled by a very wide 

 brown zone. Length 23 1 /2> diam. 11 mm. 



" Station: on the trunks of trees. 



* ' Habitat : Makiki, on Oahu. Two or three specimens have 

 been found in Palolo. Affinities: It is intermediate between 

 A. adusta Ev. and A. buddii Nwc." (Smith). 



The type-specimen is figured, pi. 38, fig. 15. It is no. 75 of 

 Gulick's type series, Boston Society. The original figure 

 shows the aperture too narrow, and the two lines near the 

 middle of the last whorl too strong. They are barely visible. 

 The shell is white, pale buff behind the outer lip and on the 

 parietal wall of the aperture, where several darker, isabella 

 colored lines or narrow bands are indistinctly visible. The 

 first half-whorl is ocher-red, the next whorl violet-plumbeous
