LAND- AND FRESHWATER SHELLS. 147 



4. Nanina haliensis Mousson. 



Martens, Ostas. Landschn. p. 207. — Mousson, Journ. 

 Conch. 1857, p. 155; pi. VI, fig. 6. 



Localities : Massoe , central S. E. Soemba , one fine 

 specimen; near Waingapoe, one rather bad specimen; from 

 the coast of Taimanoek, N. Soemba, and from a brook 

 between Pensadoe Kopol and 'N datas, bleached specimens 

 (subfossil?;. 



I sent the fresh specimen from the first-mentioned locality 

 to Prof. 7. Martens , having no specimens of the typical 

 N. haliensis for comparison , the shape being more depressed 

 than in the figures given by von Martens and Mousson. 



Prof. V. Martens writes: »sehr ahnlich N. haliensis 

 Mouss. ; ich habe Exemplare von Mousson , von denen eines 

 oder zwei eine beinahe ebenso gedrückte letzte Windung 

 haben, und die Farbung der Schnecke ist fast in der 

 Mitte zwischen der achten haliensis und var. Waandersiana" . 

 — As all the specimens have the same depressed form I 

 name them : 



var. soemhaensis. 



Shell more depressed than the type , especially the last 

 whorl ; colour purplish , last whorl with fragments of a 

 yellowish epidermis , suture margined with opaque white , 

 last whorl nearly angular. 



Diam. maj. 33, min. 29, alt. 25 mill. 



Compared with the figure of N. haliensis of Mousson, 

 1. c, the last whorl is more depressed and the colour paler, 

 approaching that of N. Waandersiana (1. c. fig. 1), which 

 has however two brown bands , with an intermediate white 

 one; the specimen of Massoe has a very narrow white 

 band at the periphery, that of Waingapoe shows only the 

 sutural line, if wetted; the other specimens are too much 

 faded to recognize the colours.
