444 Evolution and Distribution of Fishes 



Zealand Is Chiltonia, whose nearest ally Is Hyalella from 

 Lake TItlcaca on the Andes, and temperate South 

 America." 



A striking feature of the Kerguelen Insects, as of the 

 celebrated "wingless birds" of the Southern Hemisphere, 

 is the large number of nearly or completely apterous types. 



As to the earthworms Lankester observes, regarding 

 the only genus found in Kerguelen, that of four known 

 species two are from New Caledonia, one Is from Mada- 

 gascar, and one from Kerguelen. E. A. Smith notes that 

 of ten or eleven species of echlnoderms known from Pata- 

 gonia four are also Indigenous to Kerguelen. 



R. B. Sharpe's treatment of the Kerguelen birds Is alike 

 careful and suggestive. The great majority show a distri- 

 bution that eminently favors a former continuous land 

 connection, and though most are shore or marine birds, 

 their feeding habits would scarcely explain passage of them 

 across wide ocean stretches, while in the case of the pen- 

 guins their entire structure prohibits extensive or rapid mi- 

 grations. 



The distribution of a few only of the birds, amongst 

 others equally striking, can be given. Thus Larus domini- 

 camis (p. 107) Is recorded from Valparaiso, Straits of 

 Magellan, East Patagonia, Cape of Good Hope, Kergue- 

 len, and New Zealand. Stercorarhis antarcticiis occurs 

 In the Antarctic seas, S. Africa, Kerguelen, Campbell 

 Island, New Zealand, and Norfolk Islands. Daption 

 capensis Is known from Valparaiso, the Cape of Good 

 Hope, Kerguelen, N. Zealand, and W. Australia. Prion 

 vittatiis and P. desolatus extend from the Cape Seas east- 

 ward to Australia. The penguins are all Instructive, but 

 "the rockhopper" {Eudyptes saltator) deserves mention, 

 for It extends from the Falklands, Bounty, Tristan da 

 Cunha, to the Cape of Good Hope and Kerguelen. 



Though much Importance need not be attached to the 

 distribution of so thoroughly a marine group as the seals, 

 yet their origin as a relatively recent mammalian offshoot 

 should be remembered. When then the Sea Leopard 

 {Ogmoj-hinus leptonyx) is "met with In South Georgia, 

 the Falklands, Kerguelen, South Australia, Tasmania, N.
