172 TODUS. 



between Eurystomus^ Todus, and one of the types of 

 Alcedo, as well as with Eurylaimas and Muscicapa, 

 all flat-billed groups. But there is as much difference, 

 in other respects, between Eurystomus and Todus, 

 as there is between Platyrhynchus cancromus and 

 Eurylaimus. They are all, in fact, either directly 

 or indirectly, fissirostral types, whatever may be 

 their local rank in relation to other groups : and if 

 the form of the bill was to decide the location of a 

 bird, all these, nay, the whole of the fissirostral 

 types throughout ornithology, might, on such a 

 principle, be placed by themselves in a distinct 

 division. But before proceeding further, we shall 

 annex the figures and descriptions of three of the 

 most remarkable birds just mentioned.
