It seemed now quite certain, from the researches of Dr. E. GrafFe 

 {cf. J. f. O. 1870, p. 41G), that the true F. tubvensis was found in 

 the Tonga group, not, indeed, on the island of Tongatabu, but on 

 the adjoining island of Eua or Eoua of that group. ]Mr. Sclater 

 was therefore not yet quite convinced, in spite of what Messrs. 

 Finsch and Hartkub had stated (J. f. Orn. 18/0, p. 123), that 

 Peale's P. atrigvlaris (which he had identified, P. Z. S. 18(i4, p. 1 58, 

 as applicable to Mr. Rayner's specimen from Ngau Island, Feejees) 

 was certainly = P. tabuensis, unless, indeed, it should turn out that 

 P. tabuensis had been introduced by the natives of the Tonga 

 Islands from the Feejee group *.

The first two species here described were lent to me by Lieut. 

 Roberts soon after his arrival in England ; but press of work has pre- 

 vented me from determining their affinities until now.

Wings with rounded outer margin broad, costal nervure of pri- 

 maries terminating abruptly at about the middle of the costa, opposite 

 to the end of the discoidal cell, subcostal with five branches, the last 

 two forking to apex ; upper radial emitted from the inferior margin 

 of the subcostal near its origin ; lower radial nearly equally dividing 

 the discocellulars, which are concave ; second and third mediiui 

 branches emitted near together; [irecostal of secondaries short, 

 oblique, directed backwards ; costal nervure short, straight, oblique, 

 terminating at basal third of costa ; subcostal forking beyond the 



* Mr. Salvin kindly sends me an extract from the "Voyage in search of La 

 Perouse" (translated from the French, 2 vols. 8vo, 1800) in illustration of this 

 point. "On the morning of the 2(ith March we landed (on Tongataboo). . . . 

 They (the natives) sold us several birds; among others a charming species of 

 Lory, which they assured us had been brought them from Fidgi." — Tom. cit.
