34 AMASTRA. 



Whether constantly distinct remains to be worked out. No 

 new material bearing on this form was obtained in the 

 expedition of 1913. 



AMASTRA OP LANAI. 



A. AUROSTOMA Baldwin. PL 8, figs. 9, 10, 11. 



Vol. XXI, p. 240. Specimens with the cuticle figured in 

 zigzag stripes were taken by Mr. Thaanum near Kaalele Paaka 

 (main ridge east of Lanaihale). In part of the shells this 

 pattern gives place to uniform black on the last whorl. The 

 under color is pale yellow orange or yellow ocher. The 

 largest shells have the aperture and parietal callus white.

A. PULLATA Baldwin. PI. 8, figs. 7, 8. 



Vol. XXI, p. 261. To the figures cited in Vol. XXI add

 lake (Cooke & Pilsbry). Kalamaula (Thaanum). Head of 

 Makakupaia gulches (Thaanum). Two specimens from the 

 last locality are figured to show the extremes of shape, the 

 more slender shells running into var. subnigra. Pipe-line 

 trail near and at its head, upper Kaunakakai (Cooke & 

 Pilsbry), mostly of the subnigra shape, but some shells nearly 

 typical pullata ; last whorl sometimes variegated, usually deep 

 brown or black. 



Var. unibrosa was taken by Pilsbry and Cooke in the ravine 

 east of Makolelau house, and in the northwestern ravine of 

 Kamalo, above the old irrigation ditch.
