In my specimen of the present species the throat is slightly speckled 
with whitish. 
3. RAMPHOCENUS CINEREIVENTRIS, Sclater. (Pl. LXXXVII.) 
R. olivaceo-brunneus ; capitis lateribus rufis, spatio postoculari 
nigro: alis extus brunnescentibus : gutture albo, nigro-cineras- 
cente striato: abdomine cinerascente, medialiter albescentiore, 
lateraliter autem olivascentiore: cauda nigricanti-fusca : rostri 
mandibula superiore nigrescente, hujus autem apice et mandi- 
bula inferiore albidis.

A third species of this peculiar genus, beautifully intermediate in 
colouring as in locality between the Ramphocenus melanurus of 
Brazil and the rufiventris of Central America. When I say a third 
species, I am perhaps doing an injustice to M. Lesson, who has 
already described a third and a fourth. But I have never seen the 
Ramphoceni trinitatis* and viridis}, and indeed they are hardly 
likely to be recognized again from such meagre descriptions. 
The Ramphocenus cinereiventris, of which there is only one 
example in the Derby Museum, was procured at Pasto, in the 
mountains of New Grenada, by the indefatigable Delattre. It is a 
rather shorter-billed bird than the other two to which I have com- 
pared it. Like R. rufiventris, it has the sides of the head rufous, 
but differs in showing a well-marked postocular spot. It is also 
striated on the throat lixe that species, but has no tinge of rufous on 
the abdomen, which is darkish cinereous. The tail of the specimen, 
I regret to say, is not quite perfect, but there is no appearance of the 
white markings which are the distinguishing characteristic of the 
Guatimalan bird. 
The Derby Museum contains examples of R. rufiventris from 
Coban and Panama, and also specimens of R. melanurus. The latter 
species appears to extend from the Amazon, where Mr. Wallace 
collected specimens in the neighbourhood of Para, to South Brazil, 
where Prince Maximilian of Neuwied notices its occurrence under 
the name of T'roglodytes gladiator, Beit. iii. p. 751. 
4, CyPHORINUS ALBIGULARIS, Sclater. (Pl. LXXXVIII.) 
C. intense rufo-brunneus: alis extus obsolete nigro-fasciolatis ; 
cauda nigra, brunneo fasciata: capitis lateribus nigris; super- 
ciliis posticis et gutture toto pure albis: abdomine crissoque 
nigris, fasciis minutis albidis transvittatis: rostro nigro, tomiis 
pallidis : pedibus nigris. 
Long. tota 5°75, alee 2°7, caude 2:1.

This fine large typical Cyphorinus, distinguishable by its pure white 
throat and dark closely-banded under plumage, is also due to the
