MISCELLANEOUS. 



On a Collection of Pteropods and Heterojaods. 

 By F. P. Maerat. 



The following collection of Pteropods and Heteropods was ob- 

 tained by Capt. Whiteway, of the ship ' Annie Cheshyre,' during 

 several voyages from Liverpool to Valparaiso. This gentleman has 

 been in the habit of collecting various marine objects, and with the 

 utmost Hberality has given them to our local museums and private 

 collectors. It is truly surprising to find what a very large number of 

 interesting specimens have been procured by the indefatigable exer- 

 tions of a single individual. The following list comprises only one 

 section of his work. The specimens were placed in my hands, and 

 were found to include the following species : —
