ACHATINELLA FULGENS. 195 



two broad chestnut zones, leaving a yellow band at periphery 

 and a yellow line below the suture. A beautiful and unique 

 specimen in the Spalding collection, pi. 43, fig. 2, from Waia- 

 lae iki, has a green-streaked base and a broad chestnut black 

 zone above. Figs. 5 to 6& are from specimens taken by Gu- 

 lick; the other figures of Waialae shells, 1 to 4c, are from 

 more recently collected examples. On the Waialae-Palolo 

 division ridge Mr. Thurston collected a fine series of augusta, 

 rather small shells. It may be a pure colony. 



Palolo. PI. 36, figs. I to If pi. 37, figs. 7 to 9, coll. by 

 Gulick. The plumata pattern is rare or wanting in Palolo, 

 where the principal patterns are varia, diversa, trilineata and 

 augusta. The varia pattern, pi. 36, figs. 1, 2, is rather char- 

 acteristic of Palolo. The shell is streaked obliquely with 

 russet or ecru olive, with an olive-brown band above, the base 

 ecru olive or brownish. In the northern ravines of Palolo 

 this pattern is associated with very fine citron-green and dark 

 green diversa with a blackish line below the suture ; diversa 

 with white bands, with or without a blackish line above the 

 periphery, and albinos. Some of these are shown in pi. 43, 

 figs. 4 to 4c, coll. by Spalding. There are also augusta with 

 white or streaked spire, mostly with a dark subsutural line. 



The fulgens pattern is rare (pi. 37, fig. 8c). A peculiar 

 modification of the trilineata pattern has a very narrow chest- 

 nut or blackish line above the periphery, pi. 37, fig. 9, coll. 

 by Gulick. This seems to be a specially Palolo pattern. 



The frequent presence of a dark line below the suture in- 

 dicates affinity to A. stewartii. Rare individuals from the 

 northwestern ravine of Palolo are indistinguishable from A. 

 stewartii. 



Dr. Newcomb defined a " Var. &, chestnut colored above, 

 yellowish below, with two black and one white band, with 

 columella dark brown, of large size, measuring 22 x 10 twen- 

 tieths of an inch. This last variety may upon further exami- 

 nation prove to be a distinct species. The locality of this 

 last is Makika valley, mauka roa, or far back in the mountain 

 range.' I am pretty confident that Newcomb was mistaken 

 about the locality of this variety. Nothing like it is found in
