464 MOMOTID^. 



the conspicuous black stripe, bordered with blue, of the middle of the throat perhaps 

 represents the black pectoral spot of many other species ; the conspicuous superciliary 

 stripe is a modification of the blue cincture of Momotus lessoni and its allies. The tail 

 differs from that of all other species in having the two central feathers very much 

 longer than the rest, and ending in a very large spatule, between which and the ends of 

 the next pair of feathers the shaft is denuded. 



The range of Eumomota is restricted to Central America — in the north occurring in 

 Yucatan and Tehuantepec, and in the south not passing beyond the limits of Costa 

 Rica.
