. Note on the Call-Bladder, and some other points in the anatomy 
of the Toucans and Barbets ( Capitonidce ). P. Z. S. 1882, pp. 94-96. 
In connection with the peculiar shape of the gall-bladder in Toucans 
and Woodpeckers, other anatomical points are mentioned, in which the 
Rhanychastidce and Capitonidce prove to be closely allied to the Picidcc. 
. On some points in the Anatomy of the Indian Darter ( Plotus 
melanog aster), aud on the mechanism of the neck in the Darters 
(Plotus), in connection with their habits. Tom. cit. pp. 208-212. 
Certain differences between the peculiar stomachs of the Indian, West 
African, and South American species of Darters are pointed out. The 
mode of the bird’s catching and piercing its prey by means of the 
arrangement of the structure of the neck is practically explained, with 
the help of a diagrammatic model.

position of that genus. Tom. cit pp. 267-270. 
Mesites, Eurypyga, and Rhinochetus are probably the only living descend-
