Area 39: North Central Waimano-North Waimano Ridge, 

 locality 21 iB, elevation 1,350-1,425 feet; 212B, elevation 1,400 feet, 

 I dextral, 3 sinistral; 213B, elevation 1,350-1,450 feet, 2 dextral ; 

 214B, elevation 1,500-1,560 feet, 9 dextral, all Meinecke-collected,

The shells of area 39 have a series of color patterns similar to those 

 of the shells of area 45. The only reason for separating the two 

 areas is that a few shells occur in area 39 which do not have the 

 usual solid dark base of typical A. a. cookei and dififer from the 

 patterns found in area 45. The shell may be white (pi, i, fig. 46) 

 with a single band of black or warm blackish brown below the 

 periphery of the last whorl. One white specimen with a vinaceous 

 fawn lip and a patch of black behind the edge of the lip, below 

 the periphery, was found in locality 214 B.

Sandwiched in between A. a. nigripicta (area 50), and nigripicta 

 var. 2 (area 48) is a small region containing shells with A. a. cookei 

 patterns. The usual form and color pattern of the shell (pi. i, fig. 56) 

 is more obese than the usual form in area 45, and the base is banded 

 instead of being a solid dark color. The embryonic whorls are pale 

 pinkish bufif ; postembryonic whorls white, first half of last whorl lined 

 at the edge of the periphery with olive brown, subperipheral band 

 white, 2 mm. wide, tinted with pale mouse gray, on the last half 

 whorl, peripheral band warm blackish brown, subperipheral band 

 white, I mm. wide, base of last whorl warm blackish brown, with a 

 band of cream buff and a line of amber brown. Length 19.1 mm., 

 greater diameter 13.9 mm., spire height 9.0 mm., number of 

 whorls 6\. 



The usual cookei base occurs on some specimens but the spire is 

 usually lined (pi. 7, fig. iia) ; postembryonic whorls pale pinkish 

 buff spirally lined with ochraceous tawny. This shell is also the 

 obese form. Length 19.8 mm., greater diameter 13.9 mm., spire height 

 lo.i mm. A rare pattern (pi. 7, fig. 116), and an elongate shell found
