326 Mr. O. Salviu's Visit to the 



P. aeneo-brunnescens vix viridi lavata ; pilco obscuriorc ; 

 pectoris plumis albo latcralitcr strictc marginatis : long. tot. 

 32*0 poll., alse 11 '0, caudse 9'4, tarsi 2*2, dig. mcd. c. ung. 21, 

 rostri a rictu 1*4. 



Hab. zEquat. occ. {Orion). 



Obs. P. marail et P. greeyi affinis sed colore bninnescen- 

 tiore et cervice postica immaculata sane diversa. 



The 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 



jBneo-oiivacea, maxima purpurascetis. 



viiidescenti-senea media marail, 



„ „ minor greeyi. 



feneo-brimnescens ojtoni. 



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 Cracidaj 

 {I. 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.
