APPENDIX. 
Wherever stagnant water occurs in Southern Africa, specimens of this frog will generally he 
found, and in the extensive ponds which communicate with the Salt River, near to where it enters 
Table Bay, hundreds may be procured rn a few hours. It is oftener found in water than on land, yet 
it is frequently observed on the latter close to the former, into which it instantly escapes on any cause of 
alarm. It is always covered with a thick mucus, in consequence is very slippery, and with difficulty 
retained in the hand. 
POSTSCRIPT. 
In the letter-press description of Bvfo carens , plate 68, I mentioned that I considered this Batra- 
chian would require to be regarded as the type of a group, if the absence of parotids was a constant 
character. I have now, in addition to the specimen I possessed when the above was published, six 
others, in all of which the deficiency exists, I therefore propose to sink the name Bvfo carens, and 
substitute for it ScMsmaderma lateralis.
