the Isthmus of Darien by referring six specimens obtained during Lieut. Michler’s 
exploring expedition to it rather than to P. erythropygius, to which he had previously 
considered them to belong. From the latter bird P. sanguineus differs in having the 
culmen and mandible black. Some sexual difference, according to Cassin, is found in 
the colour of the bill!. The true P. erythropygius, of which the type was obtained by 
Dr. Hind during the voyage of H.M.S. ‘Solphur,’ was said to have been shot in the 
Nicaraguan port of Realejo. As several specimens have since been sent from Western 
Ecuador by more than one collector, we have no doubt an error was made in giving 
this species a Central-American habitat which has never been confirmed. There is a 
strong lateral ridge on the side of the maxilla in both these species. 
SELENIDERA. 
Selenidera, Gould, Icones Av. pl. 7, text (1837) ; Scl. Cat. Birds Brit. Mus. xix. p. 148. 
Though the members of this genus form a very compact group, the characters by 
which to separate Selenidera from Pteroglossus are not very trenchant. The culmen 
is not quite so flat between the nostrils, but the bill otherwise is much the same as in 
that genus. There is a marked difference in the sexes, the males having a conspicuous 
long tuft of yellow feathers beneath the bare space surrounding the eye, wholly absent 
in the females. Of the seven recognized species of Selenidera only one is found 
within our limits; the other six are distributed over the South-American continent, one 
belonging to South-eastern Brazil, the rest to the Amazons Valley and Guiana. The 
range of the single Central-American species, C. spectadilis, is given below.
