Describes in great detaU tlie skeleton of Todus viridis, and shows that the bird is a Coccv 

 gomorph, Its nearest living allies being the Momotidce and Alcedinidce, but having also Musci- 

 capme, Meropine, Galbuline, and Bucconine tendencies, as shown by its habits, food and 

 other peculiarities. ' 



"It maybe presumed that Todus comes of Halcyonme lineage, though its organization 

 places It m juxtaposition with the Motmots. It moreover offers structure so truly Passerine 

 as to mask its more direct allies ; and such exterior points deceived the older naturalists or 

 were too strongly insisted upon." A very elaborate and philosophical memoir.

 I. That Peltops should be referred to the family Muscicapidce. 11. That the Euryloemidce 

 ahould be assigned to the order Passeres. III. That the Todidce should be constituted a fam-
