166 PSITTACUS ERITHACUS. 



view, at one glance, of the range of all the Parrots known at the time of 

 publication (1867). This map afforded me when I first opened it, and still 

 affords me, much information and the greatest pleasure. 



Mr. Alfred R. Wallace's map of the Malay archipelago, with the red 

 line enclosing the area of the Crimson Lories, and his article on the Parrots 

 of the Malayan region (P. Z. S. 1864, p. 272) afford the greatest assistance 

 to the student. 



On the west coast of Africa P. erithacus is found from Senegambia to 

 Benguela (Ladislaus Magyar observed it in the Bihe country). Du Chaillu, 

 apparently, did not bring the species from the Gaboon ; but Reichenow found 

 it there. It appears to be very numerous on Prince's Island, but not on the 

 larger one of St. Thomas. This has been accounted for by the reason that 

 there are no rapacious birds on Prince's island, as mentioned in the following 

 excerpt (P. Z. S. 1866, p. 324). 



Dr. H. Dohrn, C.M.Z.S., in his Synopsis of the Birds of Ilha do Principe, 

 says : — " During six months' stay in Ilha do Principe I have collected birds, 

 and notes upon their habits. It seems to me the most remarkable feature 

 that not a single bird of prey exists on the island, whilst they are abundant 

 on the other two islands and on the nearest part of the continent. I saw 

 hundreds of Milvus parasiticus in San Thome ; GypoMerax angolensis and some 

 other species are not uncommon in Fernando Po ; but the whole tribe avoids 

 Principe. The inhabitants of the latter place and of San Thome assert that 

 there is a deadly hatred between the Grey Parrots (^Psittacus erythacus^ of 

 Principe and the Kites of San Thome, and that, if ever a Milvus visits the 

 neighbouring island, hundreds of Parrots fall upon him and kill him, and that 

 the Kites take revenge if perchance a Parrot should venture a trip to their 

 kingdom. There must be some family reason for this strange degree of 

 enmity ; for they seem to live in tolerable peace together on the coast." 



In a north-eastern direction Psittacus erithacus reaches Lake Tchad, 

 as Denham and Clapperton tell. To the eastern centre Heuglin found it in 

 the Wau and Bongo or Mbango country, between the rivers Djur and
