400 ZOOLOGY. 



from an actual specimen, for even Heuglin only saw- 

 it, and failed to secure examples, I add the following : —

Amydrus Blythii abounded around May en at an 

 elevation of from 3,000 to 4,000 feet in the pass below 

 Senafe. In January and February they were frequently 

 met with in flocks, which were often seen flying around 

 the rocks, their red wings flashing conspicuously in the 

 sun. I once found a great roosting-place, where evidently 

 large numbers from aU quarters collected at night. 

 It was in a ravine, where, owing to the presence of a 

 band of hard rock, the watercourse made a sudden 

 descent, and here even in the dryest season a very smaU 

 quantity of water trickled over the rocks. As in many 

 similar places where water trickled down the face of a 

 steep cliff, a large deposit of calcareous tufa had taken 

 place, and, probably owing to the subsequent wearing 

 action of the torrent, which in rainy weather rushes 

 down the ravine, had been so excavated as to form an 

 overhanging clifl", beneath which these birds took up 

 their abode at nightfall in great numbers, clinging to 

 the rock. The water also attracted numerous Cynoce- 

 phalus hamadryas Monkeys, and a few Pigeons and 

 other birds ; the principal inhabitants, however, being
