This is the most important paper on the special subject, being a monographic sketch of the 

 group, with reference to classification as based iipon anatomical structure, to geographical 

 distribution, and to the determination of the genera and species. After referring to the 

 leading authorities upon the subject, the writer remarks upon the whole family and its geo- 

 graphical distribution, and proposes to divide it into two sections, readily distinguished by 

 the structure of the feet. In one of the these, Caprimulgince proper, the outer digit has only 

 four phalanges, and the claw of the third or middle digit is pectinated ; while in the other 

 the same claw is not peculiar, and the fourth digit has the usual number of phalanges, five. 

 The sternum also offers important characters, as was shown by Blanchard. (Ann. du Mii».
