whicb incliuU's but Nixtei'ii species. In tlie Old World the ;;('.iiis Riimi 

 occuis everywhere exeeptinj;^ in the Australian realm, with the excep- 

 tion of a single species in north Australia, and two in >i'ew Guinea. 

 The h'aiKt pajma Loss, is found in New (Ininea and on the noilliern 

 peninsula (Cape York) of Australia. Otheiwise the hatrachian fauna 

 of Australia is arciferous. Its absence from South Amtiica is absolut*', 

 and tiie oiil.v genus which is nearly related to it, Rainila I'et., has but 

 four species. 



The relations of the prefrontal and ethmoid bones are very various in 

 this genus, lurnishing us with illustrations t»f most of the types found 

 throughout the order, which are usually characteristic of higher groups. 

 The names of the fauna' in the accompanying tattle refer to the species 

 of IJanidie as given in the second column. 



A coincidence between the coiulition of these itrefrontal bones and 

 the regions inhabited hy the sjtecies is evident, as well as a certain suc- 

 cession in the hitter: Neotroiiical lirst, Paheotroitical last.

The North American Kaiiu' belong apparently to thirteen species. 

 Three of these present us with six subspecies additional to their typ- 

 ical forms, whose distinctive characters approach those of species. Two 

 of the si)ecies of the West Coast are not distinguishable, excepting as 

 subsi>ecies, from two of the Pahearctic realm, which rauge from Eu-
