another and undescribed one. Of Conirosti'um he particularizes 4 species, of 
which one is doubtful j to Diglossa he refers 13 species, arranging them in the 
subgenera Diglossa, Tephrodiglossa, Pgrrhodiglossa, Cyanodiglossa, and Mela- 
nodiglossa, while under Diglossopis he mentions one single species. The 
whole of this valuable paper is worked out with that elaborate skill which 
characterizes so many, if not all, of Mr. Cassin’s contributions to Ornithology. 
Daenis uUramarina is a new species from the Isthmus of Panama, closely 
resembling D. ccerehicolor and D. cayana, but lighter than the first and darker 
than the last, and differing from both in the black of the lore not extending 
behind the eye, and the dull colour of the spot on the throat. It is the 
D. ccerebicolor of Lawrence (nec Sclater), Ann. Lyc. N. Y. vii. p. 29X. G. N. 
Lawrence, Proc. Acad. Philad. 1864, p. 106. 
Certhiola luteola is the continental species of this genus, smaller than the 
others, and not having the prominent pink lips. E. 0. Taylor, Ibis, 1864, 
p. 81. The true C. Jlaveola occurs in Porto Rico. In Dominica there is 
another species, described as new under the name of C. dominicana \ it 
differs from the last in having the yellow rump much less clearly defined, the 
throat much darker in colour, the yellow under parts much brighter and 
deeper in tint, and also wants the white outer edge of the primaries. C. alhi- 
gala from Martinique is not quite so large as the Dominican bird, is paler 
and duller yellow beneath, and the patch on the rump hardly perceptible. 
It also wants the white on the primaries ; but the most striking specific 
character is a broad white stripe down the middle of the tliroat. Id. loc. cU.

Piprites griseiceps is a new species from Costa Rica, allied to P. chlorion, 
but wanting the yellow forehead, and with an ash-coloured head. 0. Salvin, 
P. Z. S. 1864, p. 683. 
Pipra natter eri is an undescribed species, discovered byNatterer in Brazil. 
It comes near P. isidorii and P. serena, but is easily known by its green 
body-colour and pure white cap and rump. P. L. Sclater, P. Z. S. 1864, 
p. 611, pi. xxxix. 
Lipangus rufescens. The locality “ Coban,” hitherto assigned for this spe- 
cies, and for all the specimens said to have been collected by M. Delattre in 
Guatemala, is probably a mistake. P. L. Sclater and 0. Salvin, P. Z. S. 1864, 
pp. 364, 365. 
Carpodectes is a new genus, akin to Ampelio from South America, but 
having a stronger and higher bill and longer wings. The type is C. nitidus, 
a new species from Costa Rica. O. Salvin, P. Z. S. 1864, pp. 683, 684, 
pi. xxxvi.

Myiadestes melanops is a new species from Costa Rica, allied to M. unicolor, 
but with a black forehead and chin and an orange bill. 0. Salvin, P. Z. S.
