species, based ou a small collection made by Mr. E. C. J. Devis. In 

 this paper are mentioned G species which were not obtained by the 

 naturalists of the Albatross, viz, Cyanosplza {=Passeriiia) ciris, Doli- 

 dionyx oryzlvorus, Hadrostomus (undetermined species), Picus scalaris, 

 Columha leucoccnhala, and Enyyptila jamaicensis. Two supposed new 

 species were also described and one of them figured, these being Har- 

 l)orhyuchus melanostoma and Spindalis exsul (pi. v), equal, respectively, 

 to our H. guttatvs and JS. henedicU. In order to render the list of Cozumel 

 birds juore complete, it has been thought best to incorporate the addi- 

 tional species given by Mr. Salvin, but at the same time distinguishiugf 

 them typographically from the others.
