1890.] Riker and Chapman, Birds at Sautarem, Brazil. 2DO 



Taken alone it is evident this bird differs too greatly from descriptions 

 of minor to be identified with that species, but considering it in connec- 

 tion with the three remaining specimens, obviously representing different 

 stages of the same bird, it is probable that we have here the fully adult, 

 and before undescribed, plumage of Sycalis minor. The specimen de- 

 scribed is labeled "• fj> July 1, 1SS7 ;" if it be rightly sexed there can be 

 little difference in the adult plumage of both sexes. — F. M. C] 



[40. Gymnostinops yuracarium {Lafr. if- cVOrb.). — " Santarem."* 

 — F. M. C.J 



41. Ostinops decumanus {Pall.). — Common; while feeding, associates 

 with Cassicus persicus in immense flocks. 



42. Cassicus persicus {Linn.). — Common everywhere, and called by 

 the natives 'Japim.' Hundreds of their pendulous nests are sometimes 

 placed on one tree. 



43. Icterus croconotus {Wagl.). — Common about meadows where it 

 builds a pendulous nest. On account of its pleasing song it is frequently 

 kept in captivity by the natives, who call it 'Rochinal.' 



[44. Molothrus bonariensis {Gin.). — A male taken by Williams, May, 

 1S83.— F. M. C] 



45. Xanthosomus icterocephalus {Linn.). — Common in large flocks, 

 feeding on wild rice. 



[46. Amblycercus solitarius {Vicill.). — There is a single specimen of 

 this species in Mr. Riker's collection, bearing Mr. Williams's label and evi- 

 dently of his make. The label, however, is without data, but the species 

 is included here with little doubt that the specimen was taken at San- 

 tarem.— F. M. C] 



47. Gymnomystax melanicterus ( Vieill.). — Common about the river 

 in pairs, and known by the native name of 'Rochinal grande.' Builds a 

 pendulous nest about three feet in length. 



48. Leistes guianensis {Linn.). — Common about lowlands. 



[49. Cassidix oryzivora {Gm.). — A female, taken by Williams, October 

 11, 1SS3.— F. M. C] 



[50. Taenioptera nengeta {Linn.). — One example without indication 

 of sex, taken by Smith, March 13, 18S9.— F. M. C] 



51. Arundinicola leucocephala {Linn.). — Common about meadows, 

 building a covered nest in a partially submerged bush. A nest taken 

 June 20, 1887, contained two eggs. I saw scores of these nests and they 

 were invariably placed within a few inches of the nest of a large species 

 of wasp. Owing to this peculiar association the natives call the bird 

 'Mother of the Wasp.' 



[52. Fluvicolaalbiventris {Spix). — Two males, one taken by Williams, 

 June, 18S3, the other by Smith, March 9, 1S89.— F. M. C] 



537~ Todirostrum cinereum {Linn.). — A male taken July 14, 1SS4. 



[54. Todirostrum maculatum {Dcsm.). — One example, without indi- 

 cation of sex, taken by Smith, March 16, 1SS9. — F. M. C]
