212 ACHATINELLA VULPINA. 



bands is more suggestive of the four-banded pattern of 

 stewartii, such as pi. 38, fig. 6. 



Achatinella aplustre (pi. 30, fig. 51, reproduction of ori- 

 ginal figure). ' Shell conical, dextral; whorls 7, rounded; 

 suture moderately impressed, simple ; aperture semiovate ; lip 

 thin ; columella with a callus, terminating in a twisted plait, 

 bluish-white, tipped with brown ; three first spiral turns white, 

 the others with a broad central pink band margined by two 

 deep black bands ; on the last whorl, superiorly and inf eriorly, 

 is a broad bright green band. Length 1, width 10/20 inch. 

 Kolau, Oahu. 



' The gaudy coloring of this species alone separates it from 

 the A. johnsoni, nob. It belongs to the same section with 

 A. producta Reeve, which may be taken as the type of a group 

 of species numbering some half-dozen, and which requires still 

 farther additions to render it complete' (Newcomb). 



This was soon recognized as a scraped and dyed stewartii 

 or producta. 



Achatinella hybrida (pi. 30, fig. 52, reproduction of ori- 

 ginal figure). " Shell dextral, conical; whorls 6, rounded, 

 margined above, the last somewhat inflated ; suture well- 

 impressed; columella white or brownish, terminating in a 

 twisted plait; aperture ovate, white; lip simple, thickened 

 within ; striae longitudinal, fine ; color of shell green, or brown 

 on the last whorl, above white, with fine longitudinal veins of 

 the color of the epidermis. Length 18/20, width 10/20 inch. 

 Kolau, Oahu. 



"This species seems to be intermediate between A. producta 

 Reeve and A. venulata.' (Newcomb). 



18. A. VULPINA (Ferussac). Plates 39 and 40 ; pi. 41, figs. 5-7.
