In my notebook of 1861, I see "Euryale exiguum, Lamk., original of Peron and 

 Lesueur, 1803 ; young." This prosaic line is poetical for me. It takes me back to the 

 Jardin des Plantes as it was twenty years ago ; and I can see the laboratories of the 

 " Mollusques et Zoophytes," where I studied under the kindly direction of old Valen- 

 ciennes. He has gone, and so has his successor, Deshayes, and their place is now 

 worthily held by Professor Perrier, who was a very young man when first I knew him. 

 But still that poor little In-oken Astrophyton exiguum lies on its shelf, the survivor of 

 professors and of emperors.^ 



It was with a real emotion that, in unpacking the Challenger collection, I drew 

 from a large jar two fine specimens. I felt like a scholar who had found a duplicate of 

 the Codes Ai-genteus. After more than two generations the unique treasure of the 

 Jardin des Plantes has at last other representatives. To celebrate its rediscovery I could 

 not do less than give a figure of the animal.
