186 Capt. F. W. Hutton on the Birds seen 



panied us the whole way. I only saw D. chlororhynchus, Lath., 

 twice during the voyage, namely, on May 5th in lat. 41° 9' S., 

 long. 43° 7' E., and again on June 3rd in lat. 42° 51' S., long. 

 155° 17' E. 



DioMEDEA FULiGiNOSA, Gmel. A large number (about two 

 dozen) of these birds came round the ship on the 8th April, 

 when we were off the island of Tristan d^Acunha ; after that 

 they did not appear again until April 28th, in lat. 38° S., long. 

 23° E., on which day one was caught. It measured 6 feet 

 5 inches from tip to tip of its wings, and 2 feet 4 inches from 

 the culmen of the beak to the point of the tail. From this 

 time they continued with us until May 20th, in lat. 42° 23' S., 

 long. 97° 40' E., after which date none were seen until June 

 2nd, in lat. 44° 27' S., long. 150° 12' E. On that and the two 

 following days one or two followed the ship, the last being seen 

 on June 4th in lat. 40° 48' S., long. 157° 24' E. 



There is a very distinct variety of this bird, which, from its 

 resemblance to the Hooded Crow I have called var. cornicoides. 

 It is quite as common as the normal form, but inhabits rather 

 different localities. The neck, back, and body are grey, with a 

 broad black band round the beak ; and the white mark on the 

 lower mandible is very small. It is of the same size as the true 

 D. fuliginosa, and the wings and tail are the same ; but I have 

 often fancied that its flight was not as graceful. We first saw 

 this bird on April 14th in lat. 36° 28' S., long. 2° 18' E.; but it 

 did not become common until May 5th, in lat. 41° 9' S., and 

 long. 43° 7' E., from which date we saw from one to ten every 

 day until June 6th, in lat. 37° 26' S., and long. 163° 54' E., 

 when they disappeared. They vary a good deal in colour, from 

 almost white on the back of the neck and shoulders, through all 

 intermediate grades, up to that of D. fuliginosa. They got more 

 and moi'e white as we sailed eastward as far as about long. 86° E., 

 when they again got darker and darker until we left them. 



Procellaria gigantea, Gmel. First seen on April 24th, 

 in lat. 37° 32' S., long. 17° 48' E., and then occasionally until 

 we were ofi" Cape Brett, New Zealand. I have never noticed 

 one chasing another bird.
