" Obs. I have had three indifferent skins of this species (collected 

 by M. Botteri near Orizaba) for several years without being able to 

 identify it satisfactorily. M. Boucard's recent collections having 

 contained excellently prepared examples, I have been enabled to 

 make a better examination of it, and to satisfy myself that it is, as 

 far as I can tell, undescribed. It is a short-winged species, and may 

 perhaps be placed in the genus Peticcea ; but for the present it is 

 better to leave it with Zonotrichia . The fourth and fifth primaries 

 are longest, but barely exceed the third and sixth. Tbe first is rather 

 shorter than the longest secondaries. The colours of the head and 

 upper back much resemble those of Peuccea cestivalis, but the red 

 markings are rather brighter in tint in the present bird." 



The Secretary read the following extracts fiom letters received 

 from Mr. Edward Bartlett, dated November 5th, 1866, Xeberos, 

 Yurimaguas, Huallaga River, Peru :— 



" I have made a four months' expedition through the Missions of 

 the High Amazons, and have been very successful in collecting Birds, 

 Mammals, Fishes, Insects, and Shells ; I have obtained some fine 

 Humming-birds, and I hope some of them will be new." 



" I have also what I believe to be a new species of Spider Monkey, 

 a tremendous beast when alive. It has a straight, erect, golden- 

 yellow crest, a white stripe on each side of the face, belly and inside 

 flanks brownish yellow, back black ; I obtained it in the mountains. 

 The Indians regarded it as a great prize. I crossed the mountains, 

 taking with me three Indians, from Chyamatos to the Pampas on 

 the other side ; I went in search of the Cock-of-the-Rock {Rupi- 

 cola), but was not very successful ; I, however, obtained this rare 

 Monkey ; and afterwards I visited a small Indian town (three days' 

 journey from Chyamatos) in order to secure a young one of this 

 species. The Indians had it alive, and prized it very much. I, 

 however, succeeded in getting the ugly little beast, which is alive 

 and well ; it does not differ in marking from the adult, but is not 

 so bright in colour. From here I intend to visit the mouth of the 

 Huallaga, and pass up the Amazons to the First Falls and to the 

 Indian towns on the upper river. This I shall do in a canoe, as I 

 find this the best plan. Afterward* I return to Nauta and try for 

 Porpoises and Manatees in and near the mouth of the Ucayali River, 

 as this is the only chance I have of getting these animals." 



" I have had perfect health during the last five months : but food 

 is frightfully dear — a small fowl 2s., a very little pig 20s. ; and my 

 appetite is alarming. I hope to send home the collections I have 

 made in January next by the steamer."
