stripes. Apical whorls generally filleted as in strigata and 

 multicolor. The type of nigrofilosus, which undoubtedly is 

 identical with Pfeiffer's var. gracilior, is said to have been 

 collected by Dr. Harmand on the " Montagnes de Chaudre," 

 Cambodia ; but I do not think it probable that this shell was 

 found there. 



A. maculiferus, var. strigata (Mollff. MSS.). 



Loc. Mindanao Island. 



Like gracilior, except that the ground-colour is light reddish 

 brown, with oblique stripes of the same colour, only darker. 

 I do not feel sure that this and the next variety are always 

 separable. 



A. maculiferus, var. obscura, Fulton. 

 =dextrorsus, Pf. Hel. vol. iii. p. 319. 



Loc. Mindanao Island. 



In form like typical maculiferus, but of a dirty white 

 colour, obliquely striped and sparsely spotted with faint 

 reddish brown. Apical whorls filleted as in strigata. As this 

 occurs both dextral and sinistral, Pfeiffer's name cannot be 

 used. It is remarkable that this is the only form of maculi- 

 ferus of which dextral specimens have been found. 



A. maculiferus, var. inflata, Fulton. 



= maculife>-us ) var. y, Hidalgo, Journ. de Con. 1888, pi. vi. fig. 1. 



Loc. Baranda, Philippine Islands. 



A large inflated form of a lemon-colour, with a narrow 

 white band at the suture of lower whorls ; first 2^ whorls with 

 a dark fillet at the suture. 



Long. 66 millim., maj. diam. 38 millim.

Loc. Bilatan Island (Everett), Sulu Islands (Roeseler). 



Smaller than maculiferus ; of a uniform cream-colour, with 

 a very narrow golden band at suture of lower whorls, very 

 closely and (under the lens) distinctly spirally striated.
