NO. I ACHATINELLA APEXFULVA DIXON WELCH 12"/ 



Achatinclla apexfiilva apicata (Newcoinb) Pfeiffer, Pilsbry and Cooke, Man. 

 Conch., vol. 22, pp. 325-326, 327, pi. 60, figs. 5( ?), loa, 1914. 



The holotype of A. a. conifonnis (pi. 9, fig. 18) has the first 

 embryonic whorl and a half white, remaining embryonic whorls light 

 buff ; postembryonic whorls pinkish buff axially streaked with 

 avellaneous, last whorl also spirally lined with avellaneous, last 6.4 

 mm. of the last whorl mikado brown ; impressed sutural band russet ; 

 lip and columella callus pale cinnamon pink. Length 17.5 mm., greater 

 diameter 12.7 mm., spire height 8.7 mm., number of whorls 6^. 



Distribution, area ? : Type locality Ahonui, Gulick. Holotype, 

 MCZ 3991 1. Also Kalaikoa, Wahiawa, Helemano, Gulick. These 

 last three localities are undoubtedly an error because all subspecies 

 of A. apexfulva found today at a low elevation in the region between 

 South Kaukonahua Stream and Helemano Stream are highly localized. 

 The area occupied by a single race usually covers less than a mile in 

 extent along the top of a ridge or bottom of a gulch, and never extends 

 over two main ridges. Gulick and Smith named a series of species 

 such as conifonnis, flavida, versicolor, gulickii, and lilacea which are 

 undoubtedly distinct subspecies from highly localized localities. How- 

 ever, in the Gulick collection specimens of these very distinct forms 

 are reported from a number of widely separated locaHties. This indi- 

 cates that the Gulick collection is a mixture of shells from various 

 locaHties. This may be accounted for by the fact that most of Gulick's 

 material was obtained from natives. 



The typical color pattern of A. a. conifornds is exceedingly rare 

 in the Gulick collection in the Bishop Museum, only four juvenile 

 specimens being found. The lots from Ahonui containing these speci- 

 mens also include a diversity of patterns that belong to other sub- 

 species such as ^. a. gulickii and A. a. lilacea. 



An elongate form of the shell with a Hght shade of the typical color 

 pattern (pi. 9, fig. 19) has the embryonic whorls pale pinkish buff; 

 postembryonic whorls a yellowish hue of avellaneous, spirally lined 

 above the periphery with tilleul buff and fawn color; impressed 

 sutural band mikado brown. A darker shell of the typical color 

 pattern (pi, 9, fig. 19a), also a juvenile, has the embryonic whorls 

 light buff darkening to pinkish buff ; postembryonic whorls avellaneous 

 spirally lined and axially streaked with cameo brown, last whorl 

 finely axially streaked with verona brown and spirally lined with 

 light pinkish cinnamon. A specimen that looks like a brown form of 

 A. a. gulickii has the first postembryonic and penultimate whorls, 

 above the wood brown supraperipheral band, light drab spirally lined 

 and finely axially streaked with white, last whorl wood brown spirally
