Wing, 2.30 ; tail, 2.00 ; culmen, .45 ; depth of bill, .12; tarsus, .75 ; middle 

 toe, .42. 



The nearest ally of this species is B. capitalis, Lawr., of Barbadoes, 

 which differs in having the pileuni of a very dark, rich chestnut, in 

 having the entire sides and flanks, as well as the breast, sharply 

 streaked with rich chestnut, the yellow of the lower parts and the olive- 

 green of the upper surface much deeper, and the bill much stouter. 



There are two males and two females in the collection. 



3. Icterus curasoensis, sp. nov. 



Sp. char. — Similar to I. xanthornus (Gin.), but with the bill much 

 longer, more attenuated, and more acute, the white markings of the 

 wings much broader, and the yellow color paler. Adult $ (type, No. 

 97913, TJ. S. Nat. Mus.). Lemon-yellow, including lesser and middle 

 wing coverts, rather deeper beneath, especially on the breast and sides 

 of jugulum, the back and scapulars with a very faint olivaceous tinge. 

 Lores, extreme anterior portion of malar region, chin, throat, wings 

 (except lesser and middle coverts), and tail, black. Greater wing- 

 coverts broadly tipped and tertials broadly margined with white ; sec- 

 ondaries more narrowly, but still very distinctly, margined with white, 

 but the white extending not quite to the tips of the coverts ; second to 

 fifth primaries, inclusive, broadly edged with white at the base, tbe 

 white extending for .45 of an inch beyond the tips of the primary 

 coverts on the third quill j all the primaries, except the first, narrowly 

 edged with white from about the middle portion to the tip. Three 

 outer tail-feathers narrowly bordered at tips with grayish-white, and 

 all the rectrices with an inch (more or less) of their basal portion pale 

 lemon-yellow, more whitish on inner web, the shaft of this portion of 

 the feathers being pure white. Bill deep black, the basal angle of tbe 

 mandible plumbeous ; legs and feet dark plumbeous. Wing 3.70, tail 

 3.70, graduated for .60 of an inch; culmen 1.10, bill from nostril .80, 

 from basal angle of mandible 1.08, depth of bill through base .50: 

 tarsus 1.00, middle toe .70.* 



The examination of specimens of I. xanthornus in this connection 

 renders desirable some remarks on the latter species. In Dr. Sclater's 

 recent review of the Icterincef (Ibis, July, 1883, pp. 368, 369), the habitat 

 of I. xanthornus is given as follows : " Coast-region of Colombia and 

 Venezuela, Trinidad, Guiana, and Rio Negro. Santa Marta (Simons) ; 

 Carupano, Venezuela (Goering); Demerara (Brown); Bio Brancho 



* The measurements of the longest-billed specimen among five adultsof /. xanthornus, 

 from the main laud of northern and eastern South America (Colombia to Brazil), are 

 as follows: Wing 3.65, tail 3.65, culmen .88, bill from nostril .60, from basal angle of 

 mandible .88, depth of bill through base .50, tarsus 1.05, middle toe .80. The shortest- 

 billed example has the culmen only .75 of an inch long.
