The natives call this frog "Zing Ye," which of course 

 applies to the genus generally, for the species differ very 

 slightly. 



In this species the testes are much pigmented and lobulated. 



Its food consists largely of water-beetles. 



VII. Paludicola signifera, Boul. 



This is considerably smaller than fuscomaculata, and is 

 usually an olive-green on the back without conspicuous 

 markings. 



Its general habits seem to be the same as those of P. fus- 

 comaculata, as also its cry. It is most agile. I put this 

 species into a cage in which were many brightly coloured 

 frogs, including Phryniscus nigricans and also Phyllo- 

 medusa hypochondrialis. In this cage was also a small 

 grass snake. Hitherto it had taken no interest at all in the 

 gaudy frogs in its cage; but as soon as the little Paludicola 

 made its first spring, it was caught in mid-air by the snake. 



VIII. Paludicola falcipes (Hensel). 



Only one specimen found at Concepcion by the river side. 

 Its toes are even, long, and slender. Many of the specimens 

 in the British Museum are marked with one broad light band 

 running from nose to vent. But by no means all have this, 

 neither does it depend on sex. In the specimen which I pro- 

 cured this stripe is very much marked. 



IX. Engystoma ovale, Schn. 



This frog has a small head and pointed nose. The eyes are 

 set far forward, and there is an encircling fold just behind the 

 eyes. The fore-limbs are very small, and the general shape of 

 this frog proclaims it at once to be a burrower. The skin is 

 perfectly smooth. It is greenish brown above, yellow beneath, 

 and a bright yellow band passes up the thighs and over the
