58 Mr. D. A. Bannermau un an Ornithological 



The afternoon of May the 21st was spent in collecting in 

 the neighbourhood of Yaiza and Uga, and besides the species 

 already mentioned from these localities, Ravens and Vultures 

 were noted, and on the ride to the villages a pair of Thick- 

 knees was flushed. Butterflies were abundant in the fields 

 of tomatoes ; Painted Ladies, Bath Whites, Red Admirals, 

 Clouded Yellows, and Little Blues being the commonest kinds 

 met with. I determined to leave our present camp early on 

 the following morning, as it would have been only a waste of 

 precious time to remain here a day longer. Accordingly on 

 May the 22nd we started, on what proved to be our longest 

 march, from the Lago Januvio to San Miguel de Teguise, via 

 Arrecife, 23 miles as the crow flies. The first part of the 

 route was over the same ground as we had traversed on the 

 outward journey, as far as the bridle path leading from 

 Tiiiosa. Thence we rode over miles of uninteresting plain, 

 the ground gradually ascending to 700 feet, when we arrived 

 at the village of Tias. Short-toed Larks again became 

 plentiful; they seem to stick to the cornfields, as none were 

 noticed between Yaiza and Play a Januvio. From Tias the 

 first view of Arrecife is gained — over an immense wind- 

 swept plain without a tree or blade of grass ; the only 

 birds of interest observed on this plain were two Collared 

 Pratincoles [Glareula p. pratincold). These are very rare 

 visitors to the islands; both were obtained, and proved to be 

 a male and female with testes and ovai'y small. Finding 

 that we could not stay in Arrecife, we pushed on to Teguise, 

 900 feet above the sea, the road rising all the way over 

 extremely barren country. As we did not reach our desti- 

 nation until darkness had fallen, we were obliged to put up 

 our tents in the middle of the town itself, much to the 

 astonishment of the inhabitants on the following morning. 

 It was from Teguise that T afterwards procured a fine example 

 oiFalco peregrinus 23elegrinoides^' ivova a Spanish ornithologist, 

 who assured me that it had been shot while chasing the 

 tame pigeons in the town. A night was spent here, and
