1864.] ON A COLLECTION OF BIRDS FROM PANAMA. 353 
72. Evspiza AMERICANA (Gin.);° Lawr. J. ¢. vii. p. 298. 
73. CHRYSOMITRIS MEXICANA (Sw.); Lawr. J. ¢ vii. p. 332. 
Mr. Lawrence has also received specimens of Hedymeles ludovi- 
cianus, Linn., Spermophila lineata (Gm.), S. schistacea, Lawr., and 
Oryzoborus ethiops, Scl. 
Fam. Icreripz. 
74, OcyaLus waGteRrt (Gray & Mitch.) ; Lawr. /. c. vii. p. 297. 
Agrees with Guatemalan skins. 
75. OsTINoPs MONTEZUMA (Less.); Lawr. 1. c. vii. p. 297. 
The occurrence of this bird at Panama is curious, as on the Isthmus 
of Darien and in the valley of the Magdalena the allied O. guatimo- 
zinus takes its place. (See Cassin, Proc. Acad. Phil. 1860, -p. 138.) 
76. CassICULUS MICRORHYNCHUS, Sp. nov. 
Cassiculus uropygialis, Lawr. (nec Lafr.) J. c. vii. p. 297. 
3. Niger: uropygio coceineo: rostri mesorhinio angusto, neque 
ad basin incrassato, culmine parum incurvo. 
Long. tota 8°5, alee 5°1, caudee 3°6, tarsi 1, rostri a rictu 1°15. 
2. Mari similis, sed minor. 
There are only two described species of red-rumped Cassici—C. 
hemorrhous and C. uropygialis. Our new species is easily distin- 
guished from the former by its much smaller size, from the latter 
by its smaller and differently formed bill, the mesorhinium in C. 
uropygialis being much widened at the base, and the whole bill con- 
siderably larger. 
77. Cacicus perstcus (Linn.). 
Cassiculus icteronotus’?, Lawr. l.c. vil. p. 297. 
Mr. Lawrence’s Cacicus vitellinus (Proc. Acad. Phil. 1864, p. 107) 
is probably this species, which we cannot distinguish from the true 
C. persicus. 
78. CassicuLus prevosti (Less.); Lawr. l. ¢. vii. p. 297. 
Ranges from New Granada into Mexico. 
79. IcreRus BALTIMORE (Linn.); Lawr. J. ¢. vii. p. 331. 
The most southern locality recorded for this bird. 
80. Icrerus spurtus (Linn.) ; Lawr. /. ¢. vii. p. 331. 
Hardly smaller in size than a North American specimen in Sclater’s 
collection ; so that Prof. Baird’s views as to I. affinis being not dif- 
ferent (B. N. A. p. 547) seem quite correct. 
81. IcreRuS GIRAUDI, Cassin.
