138 THE VOYAGE OF H.M.S. CHALLENGER. 



One specimen. Inaccessible Island, Tristan da Cunha, October 16, 1873. Shot 

 sitting on the branches of a tree {Phylica arborea). 



No. 484, ? . Admiralty Islands, March 3 and 10, 1875. 



No. 508, ? . At sea, March 20, 1875. Stomach contained small Crustacea. Eyes 

 black.] 



In the adult specimen from St Paul's rocks, where the breeding-season was far 

 advanced, the feathers are much worn ; and the bird from Inaccessible Island appears 

 to be ordy a few months old, the portion of the bill in front of the mandibular angle 

 being very short and weak. Under the head of the preceding species I have already 

 remarked upon the noteworthy fact of these two Noddies being found so far south, and 

 it would be interesting to know if they breed there. The specimens from the Admiralty 

 Islands are adults. 



10. Larus ridibundus, Linn.

[No. 363, $ . Manila, January 11 and 14, 1875. Eyes brown. 

 Four specimens, two Z , two $ . Yokohama, Japan, May 1875. Eyes brown.] 

 The Manila specimen and two of the Japanese are birds of the previous year, the 

 other two are adults. One of these, a female, is remarkable for its small size, the wings 

 (allowing for a deficient primary) being only 11 "5 inches long; still I have seen and 

 possessed similar examples of diminutive females from other localities, as well as from 

 Japan and China ; and the other parts being in proportion, there is nothing else to 

 distinguish this from the ordinary form. 



11. Larus canus, Linn.

A bird of the previous year ; wing-coverts much abraded.

[No. 650, Z ■ Messier Channel, Straits of Magellan, January 4, 1876. Eyes hazel, 

 feet and bill reddish.] 



A bird of a full year old, the tail being nearly devoid of the band showing im- 

 maturity ; but the shoulders retain some brownish feathers.
