bands. Whorls about 6^, rather convex, the earlier 1^ white with a 

 black-brown apical spot ; suture with a faint white line. Aperture 

 ovate, white and showing the spots within ; lip expanded, white ; 

 columella dilated above, white or lilac tinted ; parietal callus light 

 red, thin and translucent.

A. kalaoensis FULTON, Ann. Mag. N. H. (6), xviii, p. 102 (July, 

 1896) SMITH, same vol., p. 148, pi. 10, f. 10. 



This species is intermediate between A. anncz and A. inconstans, 

 having the pink parietal wall of the former, and the spot-bands of 

 some forms of the latter species. A. maculatus, annce and kalaoensis^ 

 are doubtless closely allied and derived from a common ancestor. 

 Fig. 4 is Fulton's type, fig. 11 a more elongate specimen differing a 

 little in markings. 



13. Group of A. latestrigatus. 



Shell solid for this group, witli well-expanded, reflexed or recurved 

 lip, which is rose-colored or black. Coloring various, but spots of 

 the spire, when present, are cut by a median pale band, and there is a 

 tendency to split the continuous stripes of the last whorl or two into 

 narrow spots forming interrupted bands. There is no pinkish or rosy 

 umbilical tract.

A. FI.ORESIANUS Fulton. PL 65, figs. 17, 18, 19, 20. 



Shell narrowly perforate, sinistral, oblong-conic, solid and opaque, 

 smooth but rather lustreless, weakly striatulate. Color and pattern 

 exceedingly variable ; the first 1 J whorls are uniform pink with a
