or with reticulate scales. Feathers of back between the wings and 

 at the base of tail mostly elongate, lax, soft, as though of silk. 

 Tail with feathers various in number. (Bill straight, with tip bent.) 



In this and in the preceding family, as we learn from the inves- 

 tigations of Mueller, the lower larynx is not formed by the bronchi 

 but only by the lowest part of the trachea. To this division of 

 birds he gave in consequence the name of Tracheophones. Ahhandl.

 outer tail-feathers are shorter than those that succeed to them internally.

 particularly beetles, and on land-slugs. Comp. Jules Verreaux Notes sur
