146 LAND- AND FRESHWATER SHELLS. 



For a few species which remained doubtful, I have to 

 acknowledge the kind assistance of Prof, von Martens, 

 while Dr. Brot was so kind as to determine the Melaniae 

 or to verify my determinations. 



1. Nanina cidaris Lamarck. 



Martens , Ostas. Landschn. p. 203. 



Locality : Amarassi , Timor. 



A few juvenile specimens, the sculpture of which is 

 rather coarse, and consists of spiral striae and oblique 

 rugosities. 



2. Nanina rareguttata Mousson, 



var. venu St a Beck. 



Martens , Ostas. Landschn. p. 205 ; Taf. 9 , fig. 5 , 6. 



Locality : Adonara. 



This variety was formerly known from Flores , and was 

 recently found also on Solor near Menanga (Martens: 

 Zoologische Ergebnisse einer Reise nach Niederlandisch 

 Ost-Iudien durch Prof. Max Weber; Mollusca, p. 228); 

 it is new for Adonara. 



3. Nanina inquinata v. d. Busch. 



Martens , Ostas. Landschn. p. 207. 



Locality : Amarassi , Timor. 



The only specimen is more depressed than the figure given 

 by Philippi (Abbildungen und Beschreibungen neuer Conchy- 

 lien, I, p. 10, Helix, Taf. I, fig. 4). I should call the sculpture 

 obliquely rugose, instead of »minutissime granulata"; the 

 spots on the last whorl are transparent, calling in mind 

 those of AL rareguttata. Prof. v. Martens , who determined 

 this species , writes that though it was recorded from Java , 

 this locality has little importance , as in former times every 

 shell from the East -Indies was ascribed to that isle.
