the lower part of which, on each side, the haro skin descends for a short distance down the neck, gradually coming to a point, 

 thereby giving an arcuate form to the lower margin of the pouch ; bill brownish horn color, the lower mandible marked with 

 yellow spots ; iris pale green ; legs and feet black. 



Length, 27, (skin) ; wing, 10 ; tail, 6.50 ; bill, 2.10 ; tarsus, ] .90 ; outer too and claw, 3.10. 



The young are dark brown, with the neck and breast brownish grey ; the bill yellow, with the ridge dusky. 



Hub. — Texas, on the Rio Grande ; Cuba. 



Of this species, new to our fauna, there are seven specimens in the collection, three nearly 

 adult ; they are all from the Rio Grande. I have two fully adult specimens in my cahinet, one 

 from eastern Mexico, the other from Cuba. The bill is of moderate length, rather stout, with 

 the culmen smooth, and the sides crossed with ridges, in the same manner as in dilophus and 

 Jloridanus. 



Mr. Gundlach writes that it is abundant on the fresh water lakes and rivers of Cuba, also on 

 the sea-shore ; it breeds in August ; the nests are placed on trees resembling those of G. 

 jlondanus. 



Mr. Gray appears to have had some doubt of G. mexicanus, Brandt, being a valid species, as 



in his Genera of Birds he places it under dilophus, where he also puts Jloridanus, Aud. Tlie 



bird above described has strong and decided characters, and agrees very well with Brandt's 



description of G. mexicanus.
