bad weather, I saw a great many Shearwaters of this species 

 flying round us and noticed that they were always in 

 pairs. When we got to the Cape, Mr. W. L. 

 Sclater showed me a skin of 'this bii-d which had been 

 obtained on Inaccessible Island. I have little doubt that 

 this species breeds on one if not on all the islands of this 

 group. 



'' I make these remarks, as up to the present time the 

 breeding-ground of the Great Shearwater has not been 

 discovered." 



Terpsiphone lindsati, sp. n. 



" I have only one specimen of this bird, from the Island 

 of Mayotte, but as it is strikingly different from the other 

 species of Terpsiphone inhabiting this region, I have no 

 hesitation in describing it as distinct." 



General colour of the upper and underparts deep maroon. 

 Forehead, ear-coverts and crown deep metallic blue, the 

 feathers of the crown much elongated, and forming a 

 crest ; primaries black, narrowly edged on the outer web, 

 and more broadly on the inner web, with white. Most of 

 the greater wing-coverts white, with a black shaft-line, and 

 a blacker patch on the inner web ; innermost secondaries 

 with a varying amount of black down the middle, rectrices 

 chestnut. 



Total length about 6*3 inches, culmen 0*8, wing 3*1. 



Hah. Mayotte Island, Comoro group. 



" From the elongated crest and the general appearance of 

 this specimen I have little doubt that it is in adult plumage, 

 and never assumes a white adult stage. In this respect it 

 resembles T. comorensis, from Grand Comoro, and T. 

 vulpina, from Anjuan. 



" This species is named in honour of the Hon. Walter 

 Lindsay, to whom I am indebted for valuable assistance 

 in collecting birds during the voyage." 



Ctpselus matottensis, sp. n. 



Nearest to C. harhatus, but smaller, and with a dis- 

 tinct blue gloss on the upperparts, wings, and tail ; under
