Species of Amphidromus, Albers. 73 



A. palaceus, var. pura, Mousson, Moll. Java, 1849, p. 29, 

 pi. iii. fig. 2. 



Loc. Java. 



A white solid form with strong rugose striation. The type 

 specimen is the only one I have seen of this variety.

 no. 704, pi. cxvii. figs. 2, 3. 



Loc. Moluccas? 



A very globose form of a very thin substance, allied to 

 palaceus, but, judging from the type specimens (all I have 

 seen of this species), distinct.

Loc. Java. 



The colour of this species varies from yellow with only 

 two or three reddish-brown stripes to specimens that are 

 almost covered with variegated green and red-brown oblique 

 markings. The spiral lines, as seen in the type specimen, 

 are in most specimens not so distinct, but traces of them can 

 be found in nearly all. This species has been distributed 

 under the manuscript names of Prillwitzi and pcecilus, both of 

 Boettger. 



15. A. robustus, Fulton. 



= Winteri, var., Martens, Ost-Asien, p. 353, pi. xx. fig. 4. 



Loc. Java. 



Shell sinistral, ovate-conic, solid, obliquely striate, almost 

 imperforate, white, with two brown spiral bands commencing 

 at third whorl, above and below the suture, and continued to 

 last whorl, which has in addition one, and sometimes two, 

 other bands on its lower half ; whorls 7, convex ; lip and 

 columella white, expanded, margins joined by a white callus. 



Long. 50 millim., maj. diam. 31 millim.

This species varies greatly in size, but is easily distin- 

 guished from its allies by its coloration,
