MAMMALIA— REPTILES. 251 



amphibius). The far is blackish gray, slightly- 

 mixed with yellow, and lighter beneath ; the tail is 

 black. It is a little larger than the common rat. 

 There is also the Arvicola alliarius (Desm.), which 

 is about four inches long; fior, ash-coloured above, 

 white beneath; ears large, almost naked. Lastly, 

 the Arvicola socialis (Desm.), {Mus gregarim, Linn.); 

 fur, pale gray above, white underneath ; ears short, 

 broad, almost naked. About 2^ inches long; tail, 

 one inch. 



In the order Cetacea we find the common whale 

 {JBaleena mysticetus, Linn.) This species seems gra- 

 dually diminishing in number as well as in size. The 

 species most usually captured on our coast is the 

 hunchback (Baleena nodosa, Desm.) The flesh of 

 this whale, when properly cooked, is very wholesome 

 for consumptive persons, and is considered a great 

 luxury by the native blacks. 



We find, then, that the only representatives of 

 the class Mammalia are the rat tribe and the whales 

 among the wild animals. 



In the class Reptilia (reptiles), we find the order 

 Chelonia (the turtle tribe). This order is represented 

 by the green turtle {^Chelonia mydas, Holbrook); and 

 the hawk's-bill (^Chelonia carretta, Holbrook) is more 

 or less brown or rufous.
