concluded that C. griseiventHs is one of the rarer species of humming-birds. It 

 lives singly among rocky and inaccessible places and in deep canons. Many times 

 the collector has to shoot away several Patagona gigas in order to allovp 

 C. griseiventris to approach certain flowers. During two weeks' stay in Cajamarca I 

 obtained only eight specimens of this species. 



The Mefallura opaca also may be seen around Cajamarca. I found in !May a 

 nest attached to an adobe house, with two grown young. Generally this bird builds 

 under the roof of a house or under an overhanging cliff. 



On a hunting excursion up a cation which furnishes the water supply of 

 Cajamarca, I found a nest of Patagona gigas placed on the ground in a little 

 depression in a bank. The nest must have reared many generations of birds, judging 

 from its dimensions of 20 cm. diameter and 15 cm. height. 



I also found the nest of the same species with j'oung, attached to a branch of :i 

 cactus. 



Arriving at an elevation of 11,000 feet and entering a cave, I noticed a 

 female Oreotrochilus stolztnanni flying through the entrance. I searched the cave, 

 and was rewarded by finding a nest with eggs attached to the roof of the same. The 

 bird manages to stick some wool into a small crevice very tightly, and then builds 

 from it a hanging nest. Having made this observation, I had no difficulty in finding 

 other nests. 



At the Hacienda Santa Ursula, near Cajamarca, I saw a Patagona gigas fly from 

 ti large boulder of limestone, which was overgrown with lichen. Suspecting it to be 

 a female I searched for a nest, the bird coming sometimes within a few feet of my 

 head. This strengthened my supposition, but I had to give up the search. Next 

 day I again started the bird from the supposed nest, but did not see the exact place 

 from whence she flew, and did not find it. I had to use strategy by hiding behind 

 rocks, and only then was it possible to see the bird retuni to its nest, which was 

 placed amongst the lichen on a protruding piece of rock, and almost impossible to see 

 from any part. 



SAN IMARCOS. 



San Marcos lies about tweh'e leagues from Cajamarca, to which it is connected 

 by one of the best roads in Northern Peru. It is a small place, but has a considerable 

 extent of cultivated area in the neighbourhood. 



Wood is not so scarce as in Cajamarca ; all creeks and cailons ha\'e plenty of 

 brushwood. Here I discovered my first specimens of Cyanomyia cyaneicollis feeding 

 from \he flowers of an agave in company with Petasophora iolata, Patagona gigas, 

 and Myrtis fanny. 



Although the first-named species, the C cyaneicollis, had difficulty in 

 obtaining food from flowers where the Petasophora also fed, the Myrtis fanny was 

 entirely overlooked or tolerated, not only by the Petasoplwra, but also by the 

 Patagona gigas. 



After a day's travel, crossing the Cajamarca river and also the river Huamachuco, 

 I arrived in the Hacienda Malca. 



MALCA (CA.IAKAMHA).* 

 Hacienda i\Ialca lies on a level with the river bottom of the Huamachuco, and 

 has a temperate climate, where sugar-cane is grown. The hills are covered by low 

 Ijrushwood and cacti, the cafions with willow and pepperwood.
