olive spots ; they are deposited in a slight hollow." The Courier is 

 abundant on the plains of the Deccan, frequenting sandy bare spots 

 in flocks ; they have a peculiar habit of running for a distance at 

 great speed, then suddenly stopping and erecting the body, then 

 starting off as before. 



Subgenus Glareola. 



Glareola orientalis (Leach). 



I came across this pretty little Pratincole when shooting on a 

 stony bank in the river Bhcema. There were numbers of them 

 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.

 cisfjue laterihus cinereis ; superciliis et corpore subtus albis : 

 torque gutturali angusta nigra : lateribus cinerascentibus : 

 campterio fiavo : pedibus albis : rostra elongatiore, incurvo, 

 rubro. 

 Long, tota 5*8, alae 3*0, caudae 2"7. 

 Hab. in Nova Grenada, Bogota. 



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. pi. 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.

I described the female of this fine Tanager at the meeting of this 

 Society on the 25th of July last year. ^I. 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 

 thev were characterized as new in the Bulletins de I'Acadcmie Ilovale
