Hob. German East Africa ; Gaboon. 



In recently recording the occurrence of this extraordinary 

 Batrachian on the Benito Biver, I have pointed out that the 

 absence of teeth necessitates its removal from the Dactyletliridce to 

 the Pipidce. My notes on the skeleton have been corrected and 

 supplemented by Dr. Eidewood in the paper quoted above, dealing 

 with the hyoid and larynx and the carpus. 



BUFONIDJE. 



5. Bufo tuberostts Gthr. 



Hob. Fernando Po, Camaroons, Gaboon. 



Several specimens were obtained on the Benito Biver by 

 Mr. Bates. The upper parts are not always uniformly coloured ; 

 they are sometimes handsomely spotted or marbled with darker 

 brown, and a yellow or crimson vertebral line is often present. 



6. Bueo regularis Eeuss. 



Hab. The whole of Africa with the exception of Barbary. I 

 have, however, not myself examined specimens from the Gaboon 

 and there were none in the collection made by Mr. Bates. 



7. Bueo latifrons, sp. n. (Plate XXVII. fig. 1.) 



Crown without bony ridges ; snout short, blunt ; interorbital 

 space slightly concave, broader than the upper eyelid ; tympanum 

 distinct, three-fifths the diameter of the eye. First finger much 

 longer than second ; toes half-webbed, with single subarticular 

 tubercles ; two rather small metatarsal tubercles ; a tarsal fold. 

 The tarso-metatarsal articulation reaches the anterior border of 

 the eye. Upper parts with irregular warts, some of which may be 

 conical ; parotoids elliptic, feebly prominent, rather indistinct. 

 Olive-brown above, with or without a yellowish vertebral line, 

 with more or less symmetrical black markings ; limbs with dark 

 cross-bars ; bright pink spots on the back of the thighs ; lower 

 parts dirty white, throat greyish, breast with small greyish spots. 



Prom snout to vent 73 millim. 



Three specimens, females and young, from the Benito Biver 

 (G. L. Bates). 



This species stands very near to B. reyularis. It is distinguished 

 by the broader interorbital region, the smaller tympanum, and the 

 feebly prominent parotoid glands.
