204 ACHATINELLA SOLITARIA AND STEW ARTIE. 



belong not only to the epidermis but to the solid part of the 

 shell of A. fulgens. It has been described by Newcomb and 

 Pfeiffer as a variety of the latter species. Remarks: this 

 species is always sinistral. The specimen figured is from 

 Waialae.' (Smith and Gulick). 



The specimen figured as type has the appearance of a 

 plumata-augusta blend, the plumata pattern appearing on the 

 spire as in pi. 37, fig. 3. A purer expression of the color- 

 form is pi. 37, fig. 12; also pi. 29, fig. 24a, which Newcomb 

 figured as a variety of fulgens. 



16 l /2. A. SOLITARIA Newcomb. PL 43, fig. 9. 



"Shell ovately conical, dextral; whorls 6, flatly convex; 

 suture slightly impressed; aperture ovate; lip acute, thick- 

 ened within ; columella white, short, broad and abruptly 

 twisted ; color light chestnut, with darker longitudinal stripes ; 

 green at the base, white sutural band for the last 2% whorls, 

 brown band on the suture above. Length fourteen-twentieths, 

 width eight and one-half twentieths inch. 



"But a solitary specimen of this species has been obtained. 

 Its characters are, however, sufficiently striking to warrant 

 in giving it a place as a distinct species' (Newcomb). 



Oahu: Palolo (Newcomb). 



Achatinella solitaria NEWC., P. Z. S. 1853, p. 150, pi. 24, 

 f . 60 ; Annals of the Lye. N. H. of N. Y., vi, p. 331. 



A problematic form, possibly normal, but more likely to be 

 a smoked "dunkeri" with the suture scraped white. If New- 

 comb's locality is correct it should be a form of fulgens; but 

 a dextral Achatinellastrum in Palolo would be rather ano- 

 malous though not unique. While it is not likely that A. 

 solitaria is a valid species or subspecies, it is given place here 

 because we cannot form a well-founded opinion without seeing 

 the type-specimen. Very few examples are known, two in 

 the Cumingian collection being all that are on record. There 

 are none in Newcomb 's collection at Cornell University. The 

 original figure is reproduced photographically on my plate.
