FAMILY 12. ENGYSTOMID.E. (15 Genera, 3l%ecies.) 



GENERAL DISTRIBUTION. 



The Engystomidae are Toads without neck-glands and with the 

 tongue tied in front. They are most abundant in the Oriental 

 and Neotropical regions, especially in the latter, which contains 

 about half the known species, with isolated species in Australia, 

 Africa, and the Southern States of North America. They appear 

 to be the remnant of a once extensive and universally distributed 

 group, which has maintained itself in two remote regions, but is 

 dying out everywhere else. The genera are : 



Engystoma (9 sp.), Carolina to La Plata, with one species in 

 South China ; Diplopelma (3 sp.), South India to China and 

 Java ; Cacopus (2 sp.), Central India ; GlypJioglossus (1 sp.), Pegu ; 

 Callula (4 sp.), Sikhim, Ceylon, China, and Borneo ; Brachymerus 

 (1 sp.), South Africa; Adenomera (1 sp.), Brazil; Pachybatrachus 

 (1 sp.), Australia ; Breviceps (2 sp.), South and West Africa ; 

 Chelydobatrachus (1 sp.), West Australia; Hypopachus (1 sp.), 

 Costa Eica; Rhinoderma (1 sp.), Chili ; Atelopus (1 sp.), Cayenne 

 and Peru ; Copea (1 sp.), South America ; Paludicola (1 sp.),
