dusky. Young 9 : Similar to the adult, but with red featlier? on tbe 

 middle of the crown. Wing, 5.00-5.40; tail, 3.70-4.30; culmen, 1.30- 

 1.45. 



The only species bearing any resemblance to the present one is C. 

 santacruzi^ which, however, besides being very much smaller, has the 

 upper tailcoverts and lower rump immacuhite white, the frontlet golden- 

 yellow or orange, the lower i)arts much paler, and the white burs of the 

 upper surface much broader. AVith the exception of G. superciliaris (of 

 Cuba), it is the largest member of the genus, and in the decided pre- 

 dominance of black on the rump and lower tail-coverts is entirely 

 Ijeculiar.

* Malherbe claims (Mon. Pic. ii, p. 245, foot-note) 1853 as the date of his specific 

 name "kaupii", on the ground, that Bonaparte instituted the name " en eftet " by 

 dedicating it, in the Revue et Magazin de Zoologie for that year, to "au savant directeur 

 de Mns(?e de Darmstadt''. Inasmuch, however, as not even Dr. Kaup's name was given 

 in the passage quoted as evidence, it will readily appear that Professor Baird's specific 

 term urojjijgiaiis was really the first jiroposed.
