dark stage of plumage. Mr. Osbert Salvia met with the true Falco eleonorce on the Eastern 

 Atlas, and writes that " on two successive mornings I had the gratification of observing this 

 species. We were encamped on the banks of the Chemora, on the south side of the hills that 

 skirt the southern shore of Lake Djendeli. On the 27th of May I had been out to collect 

 specimens of the Alpine Swift (Cypselus melba), many of which I had seen flying over the plain, 

 and was returning to breakfast, when one of four Hawks which I had previously been watching 

 with some curiosity (not knowing what they were) came over my head, and fell to a discharge of 

 dust-shot. It proved to be a splendid female of H. eleonorce, in full adult dress. The following 

 morning I saw one about the same spot, but failed to get a shot. It would appear that this 

 bird is a late breeder, as the eggs in the ovary were not at all forward, and the perfect state of 

 the feathers showed that no eggs had been incubated. The plumage of this specimen retained, 

 for some time, a peculiar smell, possibly owing to the nature of its. food, which, though I neglected 

 to examine at the time, I conjecture to have consisted principally of coleoptera. Of the colouring 

 of the fleshy parts of this specimen I have the following note : — Bill blue at the base, black at 

 the tip ; cere yellowish blue ; legs yellow ; claws black ; eyelid yellow ; hides dark brown." 



The Eleonoran Falcon might, from its habits, be justly be called the Rock-Hobby ; for it 

 frequents the barren rocky islands, depositing its eggs on the ground amongst the stones, and 

 never nesting in a tree. Dr. Kriiper, during his stay on Naxos and the adjoining islands, care- 

 fully collected all possible information respecting this Falcon, and published the result of his 

 investigations in 1864 (Cab. Jouni. 1864, pp. 1-24) in extenso. The length of this article pre- 

 cludes us from inserting a full translation of it ; but we have extracted from it the following 

 notes : — " On my entomological expeditions, undertaken in the month of April, from the town of 

 Naxos, I but seldom observed this Falcon, and on the 25th of that month I saw the first small 



flock flying above Tragsea On the 6th of August I visited the islands where these Falcons 



breed, and landed first on Guiduronisi (Donkey-island), which is the largest of them. This 

 island is about a quarter of a German mile in extent, and has very steep shores, with a landing- 

 place sheltered from the north wind, the highest point on the island being about 300 feet above 

 the sea. We had hunted over about half the island without seeing a Falcon ; but when we 

 reached the most northern point a Falcon flew up about twenty-five paces in advance of me off 

 some stony ground ; and hurrying to the place, I found a nest containing two eggs. A little 

 distance further on another bird flew up, and I again found two fresh eggs." Dr. Kriiper further 

 goes on to record the finding of several more nests on the small islands, on one of which (on the 

 22nd of August) he caught the old female on her eggs. He continues : — " It does not build a 

 regular nest of twigs, but deposits its eggs on the bare ground in the sand, without any thing in 

 the way of a nest under them. Only in one instance did I find a slight nest under them ; but it 

 was merely an old Gull's nest which had been utilized. The eggs are generally placed under a 

 small or large stone, so as to be sheltered from the rain ; sometimes one finds them concealed 

 far under a rock, and I found this the case on several islands ; often, however, they were not 

 thus protected. There are two sorts of breeding-places — islands having steep cliffs, and those 

 that rise gradually out of the sea. Tragonisi and Stapodia belong to the former ; and there the 

 Falcons breed in security in the holes and precipices. In other islands where the shores are 

 only steep in places, the Falcons do not seem to affect those parts, but generally deposit their
