AURICULELLA, OAHU,. 85 



or closed umbilicus. The crest behind the lip is more emphatic 

 than in most pulchra. 



The color-patterns of Pease's specimens noted above are of 

 usual occurrence in "Waolani valley, from rather low down 

 to the peak, where the shells are rather larger up to 9 mm. 

 long, which is near enough to Pease 's measurement. As Wao- 

 lani is readily accessible from Honolulu being one of the 

 nearer little glens of the western wall of the superb Nuuanu 

 valley we select upper Waolani valley including the valley 

 flank of Waolani Peak as the type locality. Here the species 

 is abundant on leaves of shrubs along the trail. 



Besides the color-varieties mentioned above there are white 

 shells, naples or maize yellow, or greenish above the periphery ; 

 buff-pink or cinnamon shells with the spire of the same tint 

 or lighter, the peristome white, or spire slate color, the lip 

 and parietal wall chestnut-brown. Also many combinations, 

 shades and tints of all of these patterns. We have added to 

 the figures of Pease specimens (pi. 23, figs. 5, 6), others from 

 Waolani collected by one of us (pi. 23, figs. 8-13). 



Most of the specimens in Mr. Gulick's collection were 

 labeled A. solida Gk., a name which has appeared in print, 

 but has never been defined in any way, probably because Gu- 

 lick recognized its identity with pulchra. He collected great 

 numbers in many of the western valleys. 



Low in Waolani valley the average size is smaller than 

 higher up, though larger individuals also occur. Several 

 measure : 



Length 7.8, oblique diameter 4.5 mm. ; 6 whorls. 



Length 6.6, oblique diameter 3.7 mm. ; 5J^ whorls. 



Length 7.2, oblique diameter 3.6 mm. ; 6^3 whorls. 



A. pulchra ranges from the northwestern end of the main 

 range to Nuuanu valley. The greatest variety of colors is 

 found southeastward. Many colonies westward have but one 

 or two patterns. 



Maunakope. White, with the spire either slightly russet, 

 greenish -yellow, dark brown or blue ; peristome usually dark.

Halawa. Yellow above, white below the periphery; white 

 with slate or greenish spire. Fig. 16.
