4. MOIIOTUS. 323 



Adult male. Similar to M. momota, but with a more ruddy 

 tinge on the green, and the under surface of the body entirely 

 cinnaraomeous, with a green tinge on the throat ; no chestnut patch 

 on the back of the neck ; the black coronal patch reduced in size 

 and entirely surrounded by a band of silvery cobalt ; the feathers of 

 the nape tipped with ultramarine, forming a narrow terminal band 

 on the nape. 



There seem to be two races of this species, specimens from the 

 Santa Rita mountains having a broad band of silvery greenish 

 blue entirely encircling the black coronal patch. Fraser's Baba- 

 hoyo specimens also seem to belong to this race, and if they should 

 prove to be distinct, as I expect they will, they may be called 

 Momotus argenticinctus. Total length 16*5 inches, culmen 1'65, 

 wing .5-2, tail 5-8, centre tail-feathers 9, tarsus I'l.

Adult male. Similar to M. Icssoni but much larger, and distin- 

 guished by the absence of the blue line below the fore part of the 

 cheeks, which is replaced by a narrow line of emerald-green : " iris 

 lei" (7\ K. Sahno7i). Total length 20 inches, culmen 1-9, wing 

 5'9, tail 7"5, long tail-feathers 11 '.S, tarsus 1*05.
