Of these twenty families all but five are nearly universally distributed over the globe. 

 Of the remainder, four, viz. Mniotiltidae, CcErebidse, Icterida;, and Tyrannidae, are peculiar 

 to the continent of North and South America, whilst the fifth, Spheniscidse, is a product

IV. Summary op the Birds pound in each Island. 



Chatham Island. — Visited by Mr. Darwin and the officers of the ' Eugenie.' The 

 common Mimus melanotis occurs here, as well as Bendrwca aureola. The peculiar 

 genus Certhidea is represented by C. olivacea. Of Geosjnza no less than seven species 

 occur, in fact all the so-caUed species, except G. dentirostris, which may, and pro- 

 bably is, also found there, since Mr. Darwin's specimens have no locality recorded. 

 Cactornis has not yet been detected ; and of Camarhynchus, only C. iirosthemelas. The 

 widely ranging Myiarchus magnirostris completes the twelve species which are all that 

 have as yet been noticed on Chatham Island. It probably harbours its share of some 

 twenty other species, of which only a general range is given. 



Charles Island. — Visited by Mr. Darwin and the officers of the ' Eugenie.' Two 

 species of Mimus are found here — M. trifasciatus and, according to Sundevall, M. 

 melanotis, the latter also ranging through several other islands. Bendrwca aureola is 

 mentioned by Darwin as occurring throughout the islands ; but no particular island is 

 specified. Professor Sundevall, however, names Charles Island as one on which speci- 

 mens were obtained by the ofiicers of the Swedish vessel. Frogne concolor was 

 obtained by Neboux. Of Geosjnza three species have been noticed — G. magnirostris, 

 of which Mr. Darwin is the only naturalist who has obtained specimens, G.fortis, 

 the most widely ranging species of the genus, and G. nehulosa. Of Cactornis only 

 the common C. scandens has been noticed. Camarhynchus is represented by two 

 species, one, however, doubtfully C. crassirostris. The other, C. prosthemelas, is found 

 in several other islands. The only other species noticed in Charles Island is Larus 

 fuliginosus, though several others may have been obtained there whose precise origin 

 was not recorded by the collector. 



James Island. — Visited by Mr. Darwin and the oflficers of the ' Eugenie.' Mimus 

 melanotis is the Mocking-bird of this island, where Bendrmca aureola is also found. 

 It and Charles Island are the sole recorded localities iov Progne concolor. Certhidea oli-
