1882, FROM THE ARGENTINE REPUBLIC. 629 
At Punta Lara as well as Salto—in fact all over the province of 
Buenos Aires this Gull is found in abundance, flying in flocks. 
197. Popicrrs ROLLANDI, Q. et G. 
Alto Parana, Misiones, Arg. Rep., Feb. 12, 1880. 
This rare Grebe was obtained by a friend of mine on the Alto 
Parana, on the Paraguayan coast. Further particulars I cannot give. 
198. TacuyBarrus pominicus (Linn.). 
2. Punta Lara, B. Aires, Arg. Rep., Feb. 23, 1881. 
Iris brown. 
These birds are common in the lagoons of the province of Buenos 
Aires. 
199. CrypruRus CINEREUs (Gm.). 
3d. Oran, Salta, Arg. Rep., Nov. 19, 1880. 
Iris orange. 
This bird, like the rest of the family, is difficult, nay almost im- 
possible, to put up without a dog. I shot it outside the cultivated 
lands as it was scampering along in the midst of brushwood. 
200. Cryprurus Taraupa (Temm.), 
@. Campo Colorado, Oran, Salta, Arg. Rep., Nov. 4, 1880. 
Iris brown. 
Shot in the extremely dense forest as it was running about and 
scarcely visible amidst the very thick undergrowth. I afterwards 
saw three or four more during my residence in Oran. 
201. NorHura macutosa (Temm.). 
3 ¢. Concepcion, Misiones, Arg. Rep., June 22, 1881. 
Iris dark. 
These birds, as well as Pholeoptynx cunicularia, partake of the 
colour of the soil, which throughout Misiones is of a ferruginous clay, 
and differ herein completely from those of the province of Buenos 
Aires. They are so extremely tame and abundant on the fine undu- 
lating grass-lands that extend hence southwards, that in the early 
morning they come right up to the houses, and the boys knock them 
over with stones; but most certainly this is their northern limit in 
Misiones, as above this point there is nothing but dense forest. 
The egg, which is of a deep purply chocolate, is elongated and 
rather acutely pointed at both ends.
