GEOGRAPHICAL DISTRIBUTION. 
An apology is scarcely needed for entering at some length on this point in a history of a 
complete family of birds scattered over the face of the earth. W^hatever view may be taken 
of the origin of species, their present geographical distribution must form one of the most 
interesting points to the ornithologist ; for it offers a tangible channel through which he 
may apply the results of his researches to the solution of the general problems of natural 
science ; and on this point, at least, he is working hand in hand with the students of its 
other branches, and with them contributing to the accumulation of data and of valuable 
evidence for determining the past history of the earth. Its facts are incontrovertible, and 
they afford a sensible relief to the mind after the maze in which the other branches of 
ornithology are involved ; and from their investigation a new and additional value to the 
science is derived. 
The Capitonidee inhabit the tropical regions of the three great continents Asia, Africa, 
and America, or, technically speaking, the regions called respectively the Indo-Malayan, 
the Ethiopic, and the Neo-tropical. In the first they extend to about twelve degrees north 
of the tropic of Cancer into the Himalayan range; in the second they are found to about
