Observations on Lamarck's Naiades 8&-94 



"Having had the opportunity, while in Paris recently, to inspect most of the cabinets to 

 •which Lamarck refers in his description of the Naiades, I seized the opportunity to examine 

 the individual specimens from which he made his descriptions; and having made notes on 



the spot, I feel great confidence as to the facts, and trust that my judgment as to the 

 decisions on his species will be found to be correct."
