Mr. O. Salvin's Visit to the 
P. aeneo-brunnescens vix viridi lavata; pileo obscuriore; 
pectoris plumis albo lateraliter stricte marginatis: long. tot. 
32*0 poll., alee 11*0, caudae 9*4, tarsi 2’2, dig. med. c. ung. 2*1, 
rostri a rictn 1*4. 
Hab . iEquat. occ. [Orton). 
Obs. P. marail et P. greeyi affinis sed colore brunnescen- 
tiore et cervice postica immaculata sane diversa. 
Tbe white markings of the feathers of the chest of this 
species are inconspicuous, are confined to the pectoral region, 
and do not extend to the back of the neck as in the allied 
species, P. marail and P. greeyi. The species will take its 
place in our “ Clavis” of the species of the genus (P. Z. S. 
1870, p. 522) as follows :— 
a '", pileo immaculato unicolori 
seneo-olivacea, maxima. purpurascens . 
viridescenti-senea media . marail . 
„ „ minor . greeyi . 
seneo-brunnescens. ortoni . 
The single specimen obtained by Prof. Orton was shot near 
a place called Mindo, on the western slope of the volcano of 
Pichincha, in Ecuador, at an elevation of about 6000 or 7000 
feet above the level of the sea. It will be seen, by reference 
to the table of the geographical distribution of the Cracidse 
(l. c. p. 543), that this is the first species of Penelope that has 
been recognized as inhabiting Western Ecuador. 
Collection of Dr. S. Cabot , Jr ., Boston , Mass. 
Whilst in Boston I had the pleasure of examining the col¬ 
lection of birds formed by Dr. S. Cabot during his travels in 
Yucatan, amongst which I saw the following species which 
appeared to me to have especial interest:— 
Thryothorus albinucha, Cabot, Proc. Bost. Soc. N. H. ii. 
p. 258. 
I have no doubt that the Wren I described from Peten as 
T. petenicus (P. Z. S. 1863, p. 107) belongs to this species, 
the description of which I had overlooked.
