302 AMPHIBIA CADUCIBRANCHIA. [BUFO. 



tongue with the apex entire: eyes moderately projecting; above each 

 a slight protuberance studded with pores ; a larger protuberance of the 

 same kind on each side of the head behind the ears, with pores more 

 numerous and secreting a foetid humour: fore feet with four divided 

 toes; third toe longest; first and second equal, both a little shorter 

 than the fourth: hind legs moderate, scarcely longer than the body; 

 the toes on these feet semi-palmated, five in number with the rudiment 

 of a sixth; fourth toe much the longest; third a little longer than 

 the fifth : skin every-where covered with warts and pimples of 

 various sizes ; largest on the back, but most crowded beneath. (Colours.) 

 Upper parts of a lurid brownish gray, sometimes inclining to olive, at 

 other times to black ; the colour of the tubercles rufous brown : beneath 

 yellowish white; either plain, or irregularly spotted with black. 



Common in most parts of Great Britain : rare, however, in Ireland, if 

 not an introduced species in that country. Frequents the shady parts of 

 woods and gardens, cellars, and other damp places. Always a few days 

 later in spawning than the Frog ; the difference, in some seasons, amount- 

 ing to more than a fortnight. Ova deposited in long necklace-like chains. 

 Feeds on worms and insects, but is capable of remaining a long time 

 without nourishment. Said to be very long-lived. Ofcr. The Great Frog 

 of Pennant* is evidently nothing more than a large variety of this 

 species f.

 or yellowish brown; a bright yellow line down the middle 

 of the back : eyes very much elevated.

DESCRIPT. (Form.) General appearance similar to that of the last 

 species; but the eyes more projecting, with the eye-lids very much ele- 

 vated above the crown: porous protuberance behind the ears not so 

 large : toes on the fore feet more nearly equal ; the third, notwithstand- 

 ing, a little longer than the others ; first and second not shorter than 

 the fourth : hind legs not so long as the body ; the toes on these feet 

 much less palmated than in the B. vulgaris; the sixth toe scarcely at 

 all developed : skin similarly covered with warts and pimples. (Colours.) 

 Above, yellowish brown, or olivaceous, clouded here and there with 

 darker shades ; a line of bright yellow along the middle of the back ; 

 warts and pimples, especially the porous protuberance behind the eyes, 

 reddish : beneath, whitish, often spotted with black : legs marked with 

 transverse black bands. 



First observed near Revesby Abbey in Lincolnshire, by the late 

 Sir J. Banks. Has been since met with in plenty on many of the 

 heaths about London, as well as on Gamlingay Heath in Cambridge-
