Arce at Chiapam in September 1862, which agrees fairly well with 
Mr. Cassin's description of JE. nivosus, as quoted above. It has, 
however, a narrow black pectoral band, which he conjectures is 
present in the adult of his species, and is, as far as I can judge 
from the skin, somewhat smaller in its measurements, except 
the wings, which are slightly, and the tail, which is much longer. 
I feel doubtful if it really does belong to this species, as our spe¬ 
cimen differs very little from the South American JE. collaris , 
Vieill. (JE. azarce, auct.), and certainly does not confirm Mr. 
Cassinis remark respecting the distinction of the JR. nivosus from 
JE. collaris It is quite distinct from that [i. e. JR. azarce] or 
any other that has come under my notice.” Our specimen differs 
from the South American bird in the absence of the rufous on 
the sides of the neck and above and below the ends of the pec¬ 
toral band; for this reason I place it under the name of JE. 
nivosus. Its measurements are precisely those of JR. collaris, of 
which I possess two specimens—one from Mendoza, through 
Prof. Burmeister, and the other from Marambaya in Brazil, col¬ 
lected by Natterer. Long. tot. 6, alee 3 85, caudse 2, tarsi 105,

Found in flocks with the last-mentioned species. Very 
common. It occurs also and remains to breed on the Cays of the 
Belize coast.

Very abundant about the lagoons of Chiapam. 
57. Numenius longirostris, Wils.: Baird, Birds of N. A. 
p. 743. 
Not nearly so common as the last species, but found in the 
same localities. We also have a specimen which was shot near 
Duenas.
