bestowed by Professor Newton, since that ornithologist expressly 

 mentions a large frontal shield as one of the characteristics of 

 G, pyrrhorhoa. 



II. On two specimens of a Tropic-bird from Mauritius. 



In Blyth's Catalogue, under the number 1736, we find the entry, 

 " A. B., Adults, from the Mauritius. Willis Earle, Esq.," in reference 

 to two specimens of a Tropic-bird which he there designates Ph. 

 candidus. This is the P. lepturus of the British Museum Catalogue, 

 Vol. XXVI, p. 454. 



I find, however, that while specimen A of Blyth's Catalogue agrees 

 with the British Museum Catalogue description in most particulars, 

 specimen B is distinct, and resembles Phaethon americanus in having 

 shorter white tips to the first four primaries, and in having the outer web 

 of the fifth entirely black to within a short distance of the extremity. 

 Both birds also have evidently had the bill almost entirely yellow, 

 unlike that of P. lepturus as described. {See figures beloiu).
