flying about like swallows, and as they mobbed me, I concluded 
that they had nests, but though I made most diligent search could 
not find any. I procured a pair of birds: the eggs in the ovaries 
of the female were large: the crop of the female was filled to a great 
size with a species of small black beetle. This occurred in the month 
of March.

1. DESCRIPTIONS OF FOUR NEW OR LITTLE-KNOWN TANAGERS. 
By Pururp Lutvey Scuater, M.A. 
(Aves, Pl. LXXXIX.—XCII.) 
1. ARREMON ERYTHRORHYNCHUS, Sclater. (Pl. LXXXIX.) 
A. olivaceus : capite nigro; vitta mediali verticis, nucha cervi- 
cisque lateribus cinereis; superciliis et corpore subtus albis : 
torque gutturali angusta nigra: lateribus cinerascentibus : 
campterio flavo: pedibus albis: rostro elongatiore, incurvo, 
rubro. 
Long. tota 5°8, ale 3-0, caudee 2°7.

I have to thank Mr. Gould for allowing me to describe this new 
Arremon, which is from his collection. It is closely allied to my 
Arremon spectabilis (P. Z.S. 1854, p. 114. pl. 67) from Quixos, 
but may be distinguished by its more lengthened incurved and brilliant 
orange red-bill, and the yellow bend of the wing. 
2. TACHYPHONUS XANTHOPYGIUS, Sclater. (Pl. XC.) 
Tachyphonus xanthopygius, Sclater, P.Z.S.1854, p.158.pl.69( 2).

summo dilute flavo: tectricibus subalaribus albis.

I described the female of this fine Tanager at the meeting of this 
Society on the 25th of July last year. M. Parzudaki of Paris has 
lately received several examples of both sexes from Bogota. A pair 
of these passed into the hands of the Vicomte DuBus, by whom 
they were characterized as new in the Bulletins de l Académie Royale
