Mr. Charlesworth exhibited a young shell, as he supposed, of the 

 Nautilus Pompilius, which he considered worthy of notice on account 

 of its small size, its transverse diameter not exceeding half an inch. 

 The umbilicus was open throughout its entire length, and a series of 

 elegant and rather prominent striae were transversely disposed upon 

 the terminal portion of the external whorl. Mr. Charlesworth re- 

 marked, that the rarity of this shell in the early stages of its growth 

 was a singular circumstance, considering the immense number of 

 nautili which are annually imported to this country. The specimen 

 on the table was by far the smallest he had ever seen. 



The plates of the first part of Sir W. Jardine's work on Scottish 

 Salmonicia were exhibited by Mr. Yarrell.
