1872. MURIE, J. On the skeleton of Todus, with Remarks as to its Allies. <] F. Z. S., 

 May 21, 1872, pp. 664-680, pi. Iv, 20 figg. 



Describes ia great detail tlie skeleton of Todns viridis, and shovrs that the bird is a Coccy- 

 gomorph, its nearest living allies being the Momotidoe and Alcedinidce, bnt having also Musci- 

 capine, Meropine, Galbnline, and Bucoonine tendencies, as shown by its habits, food, and 

 other peculiarities. 



"It may b» presumed that Todus comes of Halcyonine lineage, though its organization 

 places it in 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.
