ACHATINELLA MUSTELINA. 345 



hue, indistinctly streaked with deep olive ; also vinaceous buff 

 to nearly white shells with few or many brownish drab, cin- 

 namon or even black spiral lines or bands a multilineata 

 pattern (pi. 63, figs. 4, 4a, 4&, Mokuleia, close to the N.-W. 

 head of Makua, coll. by Spalding). There may also be var- 

 ious combinations of these patterns in some lots. 



PL 63, figs. 5-5& are Mokuleia specimens from Gulick. PL 

 63, figs. 2, 2a are from Newcomb, without locality. Fig. 2 is a 

 very unusual pattern, which I have not seen in any other lot. 



On the edge of Makua, along the whole lower length of the 

 ridge, Mr. Spalding found a pure colony of the olivaceous 

 drab form shown in pi. 63, fig. 4a. There are also pure colo- 

 nies of the multilineata pattern : pi. 63, fig. 3, western ravines 

 of Mokuleia, coll. by Spalding. In the Gulick collection there 

 are several Mokuleia lots of "multilineata," some running into 

 "sordida," others into the olivaceous drab pattern (pi. 62, 

 figs. 1, 2). Occasional shells are white with some faint dusky 

 purplish stains and no bands. 



Makaha. On the south side of the range at the head of 

 Makaha valley, Mr. Spalding found some peculiar colonies. 

 In the northeastern extreme, under Kaala, pi. 63, fig. 1, the 

 shells are distinctly streaked with various shades of plum- 

 beous, dark olive gray and blackish brown on a white ground, 

 the streaks cut by a number of white spiral lines ; sutural mar- 

 gin white. This form is a modification of the more streaked 

 forms found in Mokuleia at the edge of Makua. It exists as a 

 pure race. 



Further down, in Makaha, back of the home clearing of 

 the Manager of Makaha plantation, arid on the edge of the 

 coffee clearing there is a race in which the tint varies from 

 nearly white with indistinct pale ochraceous salmon streaks, 

 to vinaceous pink; sutural border white. As this is a pure 

 race, it may be distinguished by the name A. mustelina maka- 

 haensis P. & C. PL 62, figs. 3, 4. 



Haleauau. Eastward of the great ridge running northeast 

 from Kaala, in Haleauau, the mustelina pattern is modified 

 somewhat by the widening of the white band below the suture. 

 Usually there are light streaks and spi -al lines in the dark
