THE AMPHIBIA IN GENERAL iv 



which has been described and which is characterized 

 by possessing a vermilion red color, is said by Gage to be 

 only an immature form of this species. Egg laying was 

 found by Jordan to take place near Worcester, Massachu- 

 setts, from about April 10 to June. The eggs are laid in 

 small nests attached to masses of vegetation, or wrapped 

 within leaves of aquatic plants. 



THE ANTIRA 



The Anura, or tailless Amphibia, have a short, broad 

 body, with well- developed hind legs fitted for jumping. 

 They are divided by Gadow as follows : 



A. Tongue absent ...... Aglossa. 



AA. Tongue present {Phaneroglossa). 



B. Halves of the shoulder girdle overlapping 



in the middle line (Arci/era}. 

 C. Sacral diapophyses dilated. 

 D. Terminal phalanges not claw shaped. 



Ribs present. Upper jaw with teeth . Discoglossida. 

 No ribs. Upper jaw with teeth . . Pelobatidcc. 

 No ribs. Both jaws without teeth . Bufomda. 

 DD. Terminal phalanges claw shaped, usually 



supporting adhesive disks . . Hylida:. 

 CC. Sacral diapophyses cylindrical . . Cystignathidce. 



BB. Halves of the shoulder girdle meeting in 

 the middle line and forming a me- 

 dian bar {Firmisternia). 



C. Sacral diapophyses dilated . . . Engystomatida. 

 CC. Sacral diapophyses cylindrical . . Ranidce. 



The Aglossa include only a few aberrant forms character- 

 ized by the absence of a tongue and the fact that the 

 Eustachian tubes open by a single median aperture in the 

 posterior side of the palate. The most noteworthy member
