34 Descriptions of two new Species of Birds, 



A peculiarity in these latter specimens is, that the inner 

 surface of the shoulder is mottled with crimson, extending, 

 in two instances, onto the edge of the carpus, where no 

 crimson occurs in the adult bird. The Plate represents 

 (figs. 2 and 3) a male and a presumed adult female specimen 

 (No. 7) of A. consangidneus from Sumatra, and (fig. 1) a 

 male of A. cruentus from Java. 



Another apparently new species to be noticed is 



Edoliosoma alterum, sp. n. 



Volvocivora ccerulescens, Tweedd. P. Z. S. 1877, p. 759. 



The Marquis of Tweeddale, in his list of the birds col- 

 lected by Mr. Everett in the island of Zebu(/. s. c), expresses 

 an opinion that Luzon individuals of Volvocivora cceru- 

 lescens do not differ from those from Zebu; but on an 

 examination of the series obtained by Mr. Everett, it 

 would appear that the adult males, at any rate, of the Zebu 

 form may be i-eadily distinguished from those of typical 

 V. ccBrulescens of Luzon by having their black plumage 

 glossed with a strong shade of green, which in the latter 

 bird is of a shining inky bluish colour. 



I can only account for Lord Tweeddale^s statement (/. s. c), 

 that '^the adult males of V. ccerulescens are jet-black," and 

 that " Luzon individuals do not differ from Zebu examples," 

 by the supposition that the examination of the series was not 

 made in a good light. For the same reason Mr. Sharpe, 

 (Cat. B. vol. iv. Add. p. 469), has overlooked these parti- 

 culars, but now expresses himself quite satisfied of the 

 distinctness of the two forms. 



The male specimen from Valencia in the island of Negros 

 (P. Z. S. 1878, p. 283), referred to by Lord Tweeddale, may 

 belong to another representative form, but more probably 

 will be found to be in an adolescent phase of plumage of my 

 E. alterum. 



The dimensions of these two, or possibly three, races do 

 not materially differ.
