of the shell. The postembryonic whorls are white lined and banded 

 on the last whorl with hazel, in the umbilical region a patch of carob 

 brown; lip and columella callus vinaceous buff. Length 17.7 mm., 

 greater diameter 11.2 mm., number of whorls 5f. 



The other specimen B has the usual A. a. glohosa pattern similar 

 to plate I, figure 12. The type lot of three shells of A. a. glohosa 

 has one specimen marked B which is a typical A. a. vittata. 



The usual form of the shell and color pattern of A. a. glohosa 

 in the Bishop Museum (pi. i, fig. 12) has white postembryonic 

 whorls banded and lined with hazel, base entirely hazel. Length 

 17.4 mm., greater diameter 11.7 mm., spire height 9.0 mm. A speci- 

 men from the Gulick collection (pi. 4, fig. 24) has white postembry- 

 onic whorls spirally banded with cinnamon buff, which darkens on the 

 last eighth whorl to mikado brown ; impressed sutural band cinnamon.

To quote from Pilsbry and Cooke : 



Mr. Sykes remarks that this is "related to the form of A. lorata described 

 as A. nobilis, and may prove to be an extreme variety." Dr. C. Montague Cooke, 

 on examining the type in the British Museum considered it an artificially colored 

 lorata. 



The lectotype in the British Museum is not an artificially colored 

 lorata but a normal shell which is a distinct subspecies and related 

 to A. a. glohosa. A. a. hdnleyana closely resembles A. a. glohosa in 

 the shape of the bicolored embryonic whorls and in the size and color 

 of the shell. A. a. hanleyana, however, is not banded with white 

 but has a solid brown pattern above the periphery. No A. a. lorata 

 has bicolored embryonic whorls similar to those of A. a. glohosa. 

 A. a. hanleyana, however, can easily be confused with brown forms 

 of Partulina radiata Gould (see Pilsbry and Cooke, 191 2- 191 4, p. 49, 

 pi. 13, fig. 8) . The two forms are so close that I have been in doubt as 

 to whether or not to consider hanleyana a Partulina. However, I am 

 inclined to believe that it is an extinct lowland Achatinella, because 

 of its similarity to A. a. glohosa and to a sinistral Achatinella (pi. 4, 

 fig. 26) obtained by Dos Santos in Kalihi Valley, which has embryonic 

 whorls very similar to those oi A. a. hanleyana (pi. i, fig. 16). A. a. 

 hanleyana, moreover, has an impressed sutural band, a columella cal-
