 tubercles. Skin pustulous. 



SfN.Metacus, GRD. in Proc. Acad. Nat. Sci. Philad. VI, 1853, 424. 



OBSERV. The absence of parotid glands is a trait which this genus 

 has in common with Bufonella, differing from the latter chiefly by 

 the visibility of the tympanum. The fact of the tongue being entire 

 upon its posterior margin, whilst it is emarginated in Bufonella, goes 

 still further towards establishing its claims as a genus. 



METAEUS TIMIDUS, Grd. 



CAR. SPEC. Capiie magno, antice rotundo. Cute parvls pustulis 

 munita. Colore fusco-viridescente, nifjris maculis consperso. Yiita 

 a rostro, trans oculum, ad annum pot-recta. 



SPEC. CHAR. Head large and rounded anteriorly. Skin beset with 

 small pustules ; greenish-brown above, maculated with black. A 

 vitta extending from the snout, across the eye, to the shoulder. 



SYN. Metaeus timidus, GRD. in Proc. Acad. Nat. Sci. Philad. VI, 1853, 424. 



OBSERY. This, the only species so far known of its genus, is quite 

 diminutive iu size ; the greatest length of its body and head together 

 not measuring more than an inch. 



DESCR. The head forms the third of that length ; it is depressed, 

 almost flat upon its upper surface, and rounded upon the snout. It 

 is a little longer than broad, and, when viewed from above, has an 

 ovoid appearance. The body, itself, is elongated, narrowest posteriorly, 

 the general aspect being more ranine than bufonine. The legs are 

 proportionally small, though quite as much developed as in many 

 ranoids. The entire absence of both palatine and maxillary teeth 

 entitles it to a place amongst bufonoids. The inner nostrils are very 

 large, oblong-shaped, in the longitudinal direction of the head. The 

 openings of the Eustachian tubes are exceedingly minute. The tongue 

 is of medium size, subcircular, or subelliptical, entire posteriorly, and
