ACHATINELLA APEXFULVA. 323 



or pale salmon, fading upwards to light buff or ivory, some- 

 times having narrow, inconspicuous pale bands on the last 

 whorl. Sutural band narrow, usually paler than the ground- 

 color. Lip pale flesh tinted; columellar fold the same or 

 nearly white, strong; columellar margin raised. 



Length 20.3, diam. 14 mm.; 6% whorls.

"Animal when extended in motion, longer than the shell. 

 Mantle and tentacles brown, the latter with the head above, of 

 darker shade. Foot light yellow, the superior portion of 

 darker hue." (Baldwin.) 



Kawailoa (Baldwin); a ridge between Waala [Waialua?] 

 and Kawailoa gulches (Perkins) ; spur in northwestern Opae- 

 ula, on mokihana leaves (Spalding).

The rather drawn out and flat embryonic whorls are like 

 typical apexfulva, from which this race differs in color. Fig. 

 2 is the cotype figured by Baldwin ; fig. 3 a less inflated speci- 

 men from Newcomb. In the locality where Perkins collected 

 it, recorded by Sykes, "Waala" is apparently an error for 

 Waialua. Mr. Spalding has taken it at Station 14 on the map, 

 p. 277. The several localities given all mean this one colony, I 

 believe. 



Color-form duplocincta P. & C. PI. 55, figs. 6, 7, 8. 



The shell is dextral, white, encircled with two chestnut 

 bands or groups of lines, one at the periphery, the other below 

 it; lip faintly violaceous. Length 18, diam. 11 mm. Length 

 17, diam. 11.7 mm. 



The cotypes of this form are 1272, 1273 Cooke coll., 108776 

 A. N. S., and 1213 Gulick coll., Boston Soc. The former lots 

 are labelled "Wahiawa, Emerson, extinct?", three banded 

 specimens, one drawn in fig. 8, and two in which the bands 

 are very faint, a little stronger near the lip. The locality 

 seems open to doubt. The Gulick lot is from ' ' Kawailoa, east 

 side." There is one banded shell, fig. 7, and one pure white
