204 PROCEEDINGS OF THE ACADEMY OF 



in the " Proceedings of the Academj' of Natural Sciences, Phila- 

 delphia," 1865, 199, in a paper by the author; although attention 

 had been called to it in the same publication for 1860, p. 262. 



It was repeated and extended in " Origin of Genera," 1868, but 

 had been already pointed out in conversation with Dr. Wallace, 

 and probably Dr. Giinther also, in London, in 1863, a fact which 

 had probably escaped his memor}-.
