194 ACHATINELLA PULGENS. 



ern ravines of Niu, includes typical plumata and typical tri- 

 lineata patterns, with many intermediate blends. There are 

 also many white plumata, like pi. 36, fig. 6e. Dr. Newcomb's 

 fig. 24 was evidently from a Niu shell. 



Wailupe. Plate 36, figs. 3, 30; pi. 43, figs. 3 to 3c. The 

 Gulick collection contains plumata patterns, figs. 3, 30, and 

 others similar to those he obtained in Niu. Also trilineata 

 pattern. The augusta pattern, pi. 37, figs. 12, 120, was also 

 taken here by Gulick. It is not found in Niu, and has not 

 been taken in Wailupe in recent years. 



Becent collections contain streaked plumata ; trilineata like 

 pi. 36, fig. 6d; typical fulgens pattern; diversa pattern; var- 

 ious blends of diversa-plumata and trilineata-plumata pat- 

 terns; and beautiful, pure white albinos. There are also a 

 few examples of the crassidentata color-pattern, pi. 48, fig. 

 21. All of these are found in one colony. A few are illus- 

 trated, pi. 43, figs. 3 to 3c, northwestern valley of Wailupe, 

 collected by Irwin Spalding. 



Waialae. PL 37, figs. 1 to 6&. Waialae fulgens differ 

 from the Wailupe and Niu series by the prevalence of green 

 forms and the decadence of the plumata pattern. Very few 

 plumata similar to those of Niu, pi. 36, figs. 5-5d, are in the 

 Gulick collection, but in more recent collections, the plumata 

 pattern occurs in blends with other patterns, such as pi. 37, 

 figs. 3, 30, 50, 6b. The varia pattern appears here (Gulick 

 coll.) but is much more fully represented in Palolo. The 

 augusta pattern with white spire and in various blends with 

 plumata and diversa is common, pi. 37, figs. 3, 30, Waialae 

 nui, coll. by Thaanum. The trilineata pattern is rare or ab- 

 sent, but there is an abundant form with two brownish black 

 bands on a green-streaked ground, pi. 37, figs. 3c, d, e, Wai- 

 alae nui. The diversa pattern, pi. 37, figs. 40, &, c, coll. by 

 Baldwin, and fig. 5c, coll. by Gulick, is abundant. It often 

 blends with plumata, as in fig. 3g ; and there are also beauti- 

 ful dark green examples with white bands on the spire only, 

 particularly in Waialae iki. PL 36, fig. 2 is a dextral speci- 

 men from Waialae, coll. by Gulick. The fulgens pattern, pi. 

 37, fig. 1, Waialae nui, coll. by Dr. Cooke, is rare. There are
