XXII. — A List of the Formosan Reptiles ; with Notes on a few of 

 the Species, and some Remarks on a Fish (Orthagoriseus, sp.). 

 By R. Swinhoe, F.Z.S., F.G.S. &c., H.M. Viee-Consul at 

 Formosa. 



I PROCURED at Formosa the following fifteen species of Beptilia, 

 which have since been deposited in the British Museum. Dr. 

 Giinther has determined their species, and is describing the novel- 

 ties in the British Museum Catalogue now publishing. To that 

 gentleman's kindness I am indebted for the names. 



CiSTUDiNA (Tortoises). 

 1. Emys sinensis. Gray. 



Abundant about the pools and inland waters of South-west 

 Formosa, near Taiwanfoo. They were brought to me by the 

 natives there in large numbers. I forwarded five live specimens 

 to England as a present to the Gardens of the Zoological Society. 

 Three of them arrived safe, and are now exhibited in the 

 menagerie at the Regent's Park. 



2. Trionyx sinensis, Coregm. 



Very abundant in the rivers near Amoy, but rather rare in 

 South-west Formosa, where I procured but a very few examples. 

 It has a long projectile neck, and very sharp teeth, with which 

 it can inflict a severe bite. When once it seizes an object,
