166 Mr. P. L, Sclater on the Family Icteridse. 



Appendix Specierum obscurarum, 



I have now given an account of all the species of the 

 family Icteridse known to me. It has been based principally 

 upon the examination of the specimens in my own collection 

 and in that of Messrs. Salvin and Godman. In the case of 

 the last three subfamilies, I have also had the advantage of 

 consulting the series in the collection of my good friend 

 Hans, Graf v. Berlepsch, who has most kindly sent his spe- 

 cimens over to me in aid of my researches. Out of the 127 

 species which I have enumerated above '^, four only are not 

 known to me ex visit f, but have been inserted in what seem 

 to be their proper places on the authority of other authors. 

 But there remain a few other described species which, 

 although no examples of them have come under my observa- 

 tion, deserve to be mentioned in order that they may be kept 

 in the memory of future investigators. These are: — 



(1) Cassicus melanui'us, Cassin, Pr. Ac. Sc. Phil. 18G6, 

 p. 66, from Guyaquil. 



Of this bird, resembling C. persicus, but having the tail- 

 coverts and entire tail black, there is said to be a specimen at 

 Philadelphia received from the Massena collection. Is it 

 not an artefact ? 



(2) Cassicus leiccurus^ Wied, Beitr. iii. p. 1245, from S.E. 

 Brazil. 



This white-tailed Cassique seems to be a very doubtful 

 species, only known by the report of the Indians. 



(3) Molothrus cabanisi, Cassin, Pr. Ac. Sc. Phil. 1866^ 

 p. 22, from Guiana and Santa Marta. 



A uniformly coloured species allied to Lampropsar gida- 

 nensis, but larger, is quite unknown to me.
