Shell sinistral, long-conic, rather solid, lightly striatulate, glossy ; 

 the last whorl grayish-brown with narrow whitish bands and a [per- 

 ipheral] black-spotted band ; the whorls above buff- whitish with 

 squarisli blackish blotches cut by a band, the upper whorls white with 

 black apex. Aperture oblong-ovate, angular below, brown inside, 

 about two-fifths the length of the shell ; peristome rather thickened, 

 white, narrowly reflexed ; scarcely any parietal callus ; columellar 

 margin nearly straight, dilated (Martens).

Von Martens mentions two varieties: the typical, with distinct 

 blackish blotches and black-spotted band, and a paler form, orange- 

 Isabelline, with the band and blotches obsolete. The whorls are less 

 convex than in contrarius, and there is no nodule or thickening on 

 the parietal wall. The coloring of one or several narrow whitish 

 bands on- the last whorl and maculate spire is characteristic, the 

 peripheral tessellated band being sometimes obsolete. 



A. MACULATUS (Fulton). PI. 64, figs. 9, 10, 11. 



"A shorter shell than contrarius, somewhat thinner, and the whorls 

 less convex. In maculata the interrupted markings are smaller and 

 more distant from each other, and fade away on the last whorl, the 

 last half volution being quite plain except for two basal bands. Below 

 and encircling the suture of the upper whorls there is a spiral band 

 of equidistant small brown spots (Fulton). 



Celebes: Macassar (type locality, Fulton); Macassar and Ban- 

 timurong (Sarasins); Bua-Kraeng (Fruhstorfer).
