ACHATINELLA APEXFULVA. 327 



gulickii is the presence of a subperipheral light belt, which is 

 seen in various stages of development in a large proportion of 

 the shells (but by no means all), of the original lots. The 

 type-specimen, fig. 12, is one of the shortest in Mr. Gulick's 

 lots. Most shells are like fig. 10a in contour. The same color 

 pattern occurs in Wahiawa, figs. 5&, 6, 6a. The original de- 

 scription follows. 



4 i 



'Apex gulickii Sm. Shell sinistral (sometimes dextral), 

 globose-conic, glossy, striated with growth (but scarcely with 

 spiral) lines; dilute brown, streaked with ashy, encircled with 

 a white zone at the periphery; suture margined with brown; 

 spire slightly concave ; whorls 6, the first 3 or 4 pallid, a little 

 convex, the rest convex. Aperture white, receding ; peristome 

 a little dilated, thickened within, tinted with dilute rose- 

 brown; columellar fold moderately strong, whitish. Length 

 19, diam. 13 mm. 



"Var. Shell dextral; first 3 whorls pallid, the following 

 two and the last whorl having the upper half streaked with 

 cinereous-brown, the lower half yellow, zoned with cinereous- 

 brown. 



* ' Station : On trees and bushes. Habitat : this species is 

 most abundant in Kalaikoa and Ahonui, but is sometimes 

 found in valleys to the west as far as Waialei. Affinities : It 

 is allied to A. apicatus Nwc. and A. lilaceus Gk. Remarks: 

 In Ahonui, two-thirds of the specimens are sinistral. In Ka- 

 laikoa only about one-eighth are sinistral. The specimen fig- 

 ured is from Kalaikoa' (Smith}. 



The variety of gulickii described by Mr. Smith has the epi- 

 dermis yellow below the periphery, markings otherwise as in 

 the gulickii pattern. The shells are rather small and thin, 

 mainly dextral. This form, of which I figure specimens on pi. 

 58, figs. 13-13&, is really a form of A. swiftii and not closely 

 related to gulickii. The statement that this variety occurs 

 "west as far as Waialei' is incorrect, as the Waialee form 

 with yellow base is directly connected with A. valida cinerosa, 

 and in my opinion is not the same as the various yellow based 

 forms of A. swiftii. 



The pattern called A. lilaceus (pi. 60, figs. 14, 14a, topo- 

 types from Kalaikoa, Gulick coll.) has light brownish vina- 

 ceous and russet vinaceous streaks, without white bands, the
