ACHATINELLA VULPINA. 225 



In one Gulick lot from Ahuimanu there are transitional 

 specimens between colorata and the virens pattern, both green 

 and chestnut, similar to pi. 39, figs. 13, 14. These shells are 

 like those from Kahaluu, noticed below. Another lot having 

 the shell banded with deep brown, sometimes with a green 

 band above the brown, was segregated by Mr. Gulick (pi. 41, 

 fig. 8e), also from Ahuimanu. 



A series collected by Mr. Gulick in Kahaluu (a short dis- 

 tance northwest of Ahuimanu and separated therefrom by a 

 short spur), contains ill-defined colorata, the green band in- 

 distinct or diffuse, together with green, yellowish-green and 

 chestnut shells similar to pi. 39, figs. 12&, 13 and 14. Most of 

 this lot are not distinguishable from virens patterns of the 

 Kona side of the range. The colony is apparently a color ata- 

 virens mixture. All of them are sinistral. 



Kahaluu is as far west as any Achatinellastrum of the east- 

 ern or vulpina group has been traced on the northern side of 

 the mountains. 



Mr. Baldwin gives Kalihi as a locality for colorata, but he 

 must have had some unusual color-form of vulpina, or per- 

 haps he was misinformed. 



A lot of about 20 specimens of longispira in the Gulick col- 

 lections is labelled "Ahuimanu?" on the rather dubious au- 

 thority of Mr. Frick. Probably incorrect. 



I have never seen colorata from the Kona side of the range. 

 Some specimens of olivacea from Moanalua (pi. 40, fig. lie) 

 and from Waimano (pi. 41, fig. 7) have a broad green band 

 above, but they lack the dark sutural band of colorata. There 

 are also occasional specimens of the longispira pattern which 

 resemble colorata. 



A. consanguinea Smith intergrades completely with the 

 dusky forms of colorata. Probably Mr. Gulick selected the 

 specimens out of his lot of colorata. The original description 

 follows.
