ZOOLOGICAL LITERATURE. 
The author unites the Natricidce and Homalopsidce into one 
grbup^ which he calls Potamophilidce. He knows four genera of 
the former ; of the latter he admits eight genera. Interesting 
and important forms like Xenochrophis^ Hipistes, &c. are entirely 
omitted, and the list of species is very incomplete. The species 
described as new will be mentioned below, and we shall defer 
some critical remarks on them until their figures shall be pub- 
lished. 
Jerdon, T. C. Remarks on observations contained in Dr. 
Giinther^s work on the ^ Reptiles of British India.^ Ann. 
& Mag. Nat. Hist. 1865, xv. pp. 416-418. 
The author complains of the manner in which a paper of his 
on Indian Reptiles has been referred to by the Recorder. 
Jones, J. M. Contributions to the Natural History of Nova 
Scotia : Reptilia. Proc. & Trans. Nov. Scot. Inst. Sc. 
Halif. vol. ii. part 3, 1865 (pp. 114-128). 
This paper will be gratefully received by all zoologists, inas- 
much as it contributes to our scanty knowledge of the Cold- 
blooded Vertebrates of British North America. Singularly, the 
Lizards are not represented in Nova Scotia; whilst three Chelo- 
nians occur, viz. Chelydra serpentina^ Emys picta, and E. in- 
sculpta (Do Kay). Five Snakes : Coluber constrictor, Ahlahes 
punctatus, Cyctophis vei'nutis, Tropidonotus sirtalis, and Ischno- 
gnathus occipito-maculatus. Seven Frogs: Rana mugiens, clamata, 
halecina, and temporaria, Bufo americanus, Acris pickeringii, and 
Ihjla versicolor. The four Salamanders are determined as Sala- 
mandra subviolacea (Hark), S. erytkronota (Holbr.), S. salmonea, 
and Triton miltepunctatus (De Kay) .

Nassau. Nass. naturwiss. Jalirb. 1865, pp. 77-122. (Also 
separately printed.) 
This is a paper of local interest. The author enumerates 
five Saurians, four Snakes (among which Elaphis flavescens and 
Tropidonotus tessellatus), and fourteen or fifteen Batrachians. 
He adds a tabular synopsis to facilitate their determination.
