In his arrangement of the varieties of maugeri, Adams 

 places this between citrina and albida, remarking that " it is 

 of a pearl or ashy- white color." It seems, from the descrip- 

 tion, to be very similar to citrina and albida, and, in any case, 

 must be dropped, as the name is preoccupied. Locality un- 

 known. 



13c. Var. ALBIDA (C. B. Adams). PL 12, fig. 66. 



Shell fusiform, glossy and smooth, except for some very 

 fine striae behind the lip, bluish-white, the suture marked with 

 a fine white line; apex and a space behind the lip sometimes 

 faintly pink-tinted. Keel very short, blunt. Aperture 

 longer than wide, oblique, the peristome reflexed, moderately 

 thickened, white; outer lip retracted slightly above; columel- 

 lar lip projecting in a slight angle near the insertion. Colu- 

 mella more or less truncate in an oblique view in the aperture. 

 Length 18, diam. 6 mm., whorls 7%. Length 20, diam. 5.5 

 mm., whorls 8%.

Type locality unknown, but the Jarvis collection contains 

 typical examples from the locality noted above. It differs 

 from citrina by the fine white sutural line, not widening into 

 a band on the lower whorls, and sometimes inconspicuous. 



Adams thus describes albida: ll Shell like var. citrina, but 

 the white stripe reduced to an ill-defined line, slightly tinged 

 with yellow on the penult whorl, with the red tinge very 

 faint. " No locality is mentioned.
