Prof. Bickmore exhibited a specimen of Nautilus pompilius 

 in alcohol, collected by him at Amboina, which is the only speci- 

 men ever brought to this country. It has been commonly believed 

 that the Nautilus occasionally rises to and swims on the surface 

 of the water, but after repeated inquiries of the natives, Prof. 

 B. became satisfied that the animal never rises from the bed of 

 the sea. The Malays collect them for food.

Notes on certain Terrestrial Mollusca, with description of 

 new species. By Thomas Bland. 



This paper details the interesting discovery of the presence of 

 a jaw in the animal of various species of Cylindrellidse, so that 

 Crosse's genus Eucalodium, originally separated from the family 

 on account of the presence of the jaw, must now revert to it again. 



Prof. Gabb's Cyl. Newcombiana, published in this Journal iii, 

 237, t. 16, f. 3 — 4, belongs to the genus Eucalodium, which will 

 embrace the large Mexican species. Gabb's name, however, is 

 a synonym, as the same species was described by Pfeiffer, Proc. 

 Zool. Soc, 1861, 27, t. 2, f. 7, as Olamilia {Balea f) Taylori.
