1 N.B. I have followed Diesing (1850) in attributing the nomenclature in Lamarck’s 
work (1818) to de Blainville. The latter writer (1827, p. 206) states that “ M. de Blain- 
ville...a propose les memes subdivisions que M. de Lamarck a adoptees de ses manuscrits,” 
but there is no internal evidence of any further contribution. 
We are expressly told by de Blainville that he suggested to Lamarck the names 
Piscicola and Erpobdella (1828, pp. 558 and 564).
