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. Tachybaptus dominicus (Linn.). 



$ . Punta Lara, B. Aires, Arg. Rep., Feb. 23, 1881. 

 Iris brown. 



These birds are comoion in the lagoons of the province of Buenos 



Aires. 



199. Crypturus ciNEREus (Gm.). 



d. Oran, Salta, Arg. Rep., Nov. 19, 1880. 



Iris orange. 



This bird, Hke 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 iu the midst of brushwood. 



200. Crypturus tataupa (Temm.). 



2 . 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. NoTHURA MACULOSA (Temm.). 



d 2 . Concepcion, Misiones, Arg. Rep., June 22, 1881. 

 Iris dark. 



These birds, as well as Pholeophjnx 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 bovs 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. 



Meas. : axis 45 mill., diam. 31 mill.
