Seen, but not secured. 
Fam. RHYNCHOPIDZ. 
*80. Rhynchops nigra Linn. 
I found the bill and portions of the skull of this bird near the river, 
and Mr. Lange informs me that they are common during part of the 
year. 
In closing this list it is fitting that I acknowledge my deep sense of 
obligation to the following persons: 
Sr. Don ADAN CARDENAS, president of Nicaragua, for a permit to 
take my effects from the custom-house free of all duties, and for other 
favors. 
Sr. Don. Justo CARDENAS, for kind assistance in many matters. 
Sr. Don ALIJANDRO CHAMBERLAIN, for his genuine hospitality and 
courteous aid. 
M. GREEN, esq., for valuable aid and information. 
Dr. EARL FLINT and DAvID MuRRY, esq., for courtesies too numer- 
ous to mention. 
Mrs. HLIZABE1H WALSH, for oft-repeated hospitalities. 
Don JosE ANGEL LUNA and sister, and Donna CAROLINA CANTON, 
for valuable aid and information on the island of Ometepe. 
Sr. N. MARTINEZ, for kind hospitality at San Carlos. 
Mr, F. W. A. ee for ea at Los Sabalos. 
about .05 of an inch wide: anal 10-. 15 of an ince apart; crissum black, very narrowly 
barred with white, and tinged with light rufous. Lining of wing white, the basal 
half of the feathers abruptly grayish. Tibiew, uniform, deepsmoky-gray. Bill olive- 
greenish, more horn-gray terminally; ‘iris red,” legs and feet dusky; wing, 2.80;

This apparently new species is related to both P. albigularis Lawr. and P. cinereiceps — 
Lawr., but is evidently distinct. It agrees with the former in the white throat, and 
with the latter in the grayish head; but it differs from both in a number of charac- 
ters. The three are ‘so nearly allied, however, that comparative diagnoses may best 
show the differences, which are as follows: 
A. Head without any gray; wing-coverts with lighter bars. 
1. P. ALBIGULARIS. Chin and throat distinctly white; pileum russet-brown, and 
side of head rufous, Wing, 3.05-3.10; tail, 1.25-1.30; culmen, .68; tarsus, 1.18-1.20 ; 
middle toe, 1.15-1.25. Hab. Panama. 
B. Head mostly gray ; wing-coverts without lighter bars. 
2, P. LEUCOGASTRA. Chin and throat distinctly white; jugulum pale cinnamon, 
fading to white on lower breast ; white bars on sides and flanks, very narrow. Wing, 
2.80; tail, 1.10; culmen, .68; tarsus, 1.20; middle toe, 1.25. Hab. Eastern Nicaragua 
(Los Sébalos). 
3. P, CINEREICEPS. Chin and throat pale cinnamon, the former inclining to whit- 
ish; jugulum and whole breast rich chestnut-rufous ; white bars on sides and flanks. 
very broad. Wing, 2.90; tail, —; culmen, .60; tarsus, 1.15; middle toe, 1.20. Hab,
