On Birds from Central and South America. 445 



In the ' Hand-list of Birds' (i. p. 382), G. R. Gray quotes 

 under V. chlorogaster a synonym V. dubusi, Verr. I have 

 been unable to find any published description of the bird 

 under this name. I find, however, with Mr. Sharpens as- 

 sistance, that, besides the type of V. chlorogaster, there is 

 a second specimen in the British Museum, which was ac- 

 quired (apparently from Verreaux, through Cuming) in 1858, 

 and which is called in the register V. dubusi. With it the 

 Museum obtained, amongst other birds, Monarcha castanei- 

 ventris, described by Verreaux in the ' Revue de Zoologie ' 

 in 1858 (p. 304). As no description of V. dubusi appears in 

 the same paper, it seems more than probable that it never 

 was so described at all. This name, in fact, is doubtless 

 one of the many which Gray copied from the bottom of a 

 stand, or from a label, and incorporated into his ' Hand-list ' 

 to perplex us all in our searches for their origin Of the same 

 nature, perhaps, is a synonym of V. icterophrys, quoted in 

 the ' Hand-list ■" a few lines lower down, and fathered upon 

 Mr. Sclater and myself, except that in this case an evident 

 lapsus calami was most probably perpetrated by Gray's own 

 pen! 



Lastly, it remains to give the altered synonymy of V. 

 leucotis, which runs thus : — 



ViREOLANius LEUCOTIS. (Plate XI.) 



Malaconotus leucotis, Sw. An. in Menag. p. 341 (1838). 



Vireolanius icterophrys, Bp. Compt. Rend, xxxviii. p. 380, 

 et Not. Orn. p. 60 (1854) ; Baird, Rev. Am. B. p. 399 ; Scl. 

 & Saiv. Ex. Orn. p. 16; Nomencl. p. 16.

"When Mr. Sclater and I, in 1868, last revised the genus 

 Pyrgisoma (Ex. Orn. p. 128), we considered that Guatemalan 

 and Costa-Rican specimens, there called P. leucote (Cab.),
