406 Mr. G. A. Boiilenger on Cophophiyne sikkimensis, 



he notices the following as generic : — A hidden tympanum 

 and obsolete eustachian tubes, free toes, and the tongue " parted 

 behind." In the opinion of Anderson the genus Scutiger is 

 untenable, and Bomlnnator sikkimensis is referred to Bufo, 

 from which it " only differs in its free toes and in its slightly 

 notched tongue." An examination of the pupil and of the 

 skeleton reveals, however, important differential characters, 

 and I have no hesitation in accepting the generic separation, 

 although under a new name, that of Scutiger bein_a^ (I might 

 say fortunately) preoccupied [Scutiffera^ Latreitle, Myriopoda^ 

 1802). Besides, I do not consider that genus as by any 

 means closely allied to Bufo, but as a connecting form 

 between the Bufonidse, to which it must be referred on 

 account of the absence of teeth, and the Pelobatid^e, the East-. 

 Indian forms of which it approaches in the very strongly 

 dilated transverse processes of the sacral vertebra, which 

 bears but a single condyle for articulation with the coccyx 

 (there ar^e two in all Bufonidse), and the structure of the 

 sternal apparatus, which is precisely that of Leptohracliium^ 

 XenopTirySj and MegalopJirys. In some of the external 

 characters also (pupil, tongue, toes) it bears resemblance to 

 these three genera.

Pupil vertical. Vomerine teeth none. Tongue elliptic^ 

 free and very slightly nicked behind. No tympanum ; 

 eustachian tubes extremely small, scarcely perceptible. 

 Fingers free, toes nearly free, the tips not dilated. Outer 

 metatarsals united. A cartilaginous omosternum ; sternum 

 with a slender bony style. Sacral vertebra with very strongly 

 dilated diapophyses, and one condyle for articulation with 

 coccyx.

Head moderate ; snout short, rounded, with indistinct 

 canthus rostralis ; interorbital space a little narrower than the 

 upper eyelid. Fingers and toes blunt, without subarticular 

 tubercles ; first and second fingers equal • an indistinct rudi- 

 ment of web between the toes ; a large, elliptic, very feebly 

 prominent inner metatarsal tubercle ; no tarsal fold. The 

 tibio-tarsal articulation reaches the shoulder or the angle of 

 the mouth. Upper parts with large porous warts, which may
