46; 



This species agrees by the small wing with the preceding one, but its margin round 

 the impressed spire is still much blunter, the shell is more convex ; the new species is much more 

 convex than in 5". cancellahis^ the columella much more curved, the peristome more convex; 

 moreover the shell is considerably larger and the sculpture much coarser than any of the 

 species described above or otherwise described from the Indic. The specimen from Stat. 45 is 

 very young and doubtful. 



4. ScapJiandcr sp. 



Stat. 321. 6°5'.5S., ii3°3o'E. Java-sea. 82 M. Fine, grey mud. i Spec. 



The specimen long about 5^/3 Mill., probably belongs to the genus Scaphander ; as its 

 peristome is very fragile, the basal margin breken, and the shell has been broken and repaired 

 during life, I think it is preferable not to name or describe it, as it is too young and obscure. 



5. Scaphander sp. ? 



Stat. 260. Near North poiiit of Nuhu Jaan, Kei-islands. 90 M. Sand, coral and shells. 2 Spec. 



The specimens are small and decidedly young-, though the sculpture resembles that of 

 the preceding specimen, I think they do not belong to the same species; they are still less 

 worth describing.

Both specimens of this common species are very young.

 Stat. 133. Lirung, Salibabu-island. Up to 2,6 M. ^lud and hard sand. i Spec. 



Both .specimens have the appearance of being young ; as both are moreover defective 

 and the shape has no prominent characters, I think it not advisable to name them ; the shells are 

 much more elongated than the young specimens of A. nanaan and have only a very faint 

 columellar fold. The species much resembles A. hyalina Watson, but seems not to be identical, 

 as Mr. Smith, who compared it in the British Museum, has not identified it.
