principally the clitfs of the islets, such as Egg Island, where it 

 breeds in swarms. It does not appear to associate with either 

 the Tropic- or the White bird, but is one of the most abundant 

 species at St. Helena. 



[*^* Some time previously to the receipt of the foregoing 

 paper, our good friend Captain Beavan very kindly forwarded us 

 some notes on the Ornithology of St. Helena, which, for want 

 of room, we were then unable to print. We feel, therefore, 

 that some apology would be due to him for the preference we 

 have now shown to the article of a later contributor, were it not 

 for the fact that Mr. Melliss has been resident in the island for 

 some years, whereas Captain Beavan had paid but a passing visit 

 to it when on his homeward voyage in 1867, and accordingly the 

 former has had many more opportunities of making observations 

 than the latter. That Captain Beavan, however (as would be 

 expected), used his limited time (only two days) well is plain 

 from his having included in his notes every wild species men- 

 tioned by Mr. Melliss ; and he further obliged us by sending us 

 a copy of ' The St. Helena Almanac and iVnnual Register' for 

 1867, published at the office of the Govei'nment, wherein is 

 given a very brief notice of the vertebrate fauna of this island. 

 From this publication may also be gathered the fact that some 

 other species, not included by Mr. Melliss, have been imported 

 into the Island : thus, in a list of " Remarkable Events/' it is 

 mentioned that in the year 1824 "English Singing Birds '"' 

 were introduced on the 18th November, and in 1852 " Thrushes, 

 Blackbirds, Larks, and Starlings," were imported; again, in 

 1853, " South-American Mocking-Birds " were introduced. 

 From the silence of Mr. Melliss as to these species, we may 

 safely conclude that the attempts to acclimatize them, for some 

 reason or other, failed. — Ed.]
