men there are scarcely any long fine hairs to be seen ; feet 

 slender and similarly thinly clothed. No trace of a lateral 

 gland. 



The skull differs conspicuously from that of C. ruhicunda 

 in its smaller size. The teeth differ in the shape of the first 

 upper incisor as well as in the large size of the penultimate 

 premolar. The first upper incisor has a large basal process 

 provided with an internal basal cusp, the anterior principal 

 cusp of this tooth is short and does not equal that of the 

 second incisor in vertical extent ; the third incisor is smaller 

 and shorter than the anterior maxillary tooth ; the small 

 penultimate premolar is much larger than usual in the genus, 

 being about three fourths the size of the third incisor in cross 

 section at the base, and its cusp slightly exceeds in vertical 

 extent the anterior basal cusp of the last premolar ; the ante- 

 rior mandibular tooth has two notches.

Since I had the pleasure of reporting on a collection of 

 Reptiles* made by Mr. A. E. Pratt at Kiu-Kiang, on theYang- 

 tsze River, he has proceeded further inland, to Ichang, a distance 

 of 1000 miles from the mouth of the river. He was fortunate 

 enough to obtain there a specimen of the porpoise, the exist- 

 ence of which had been mentioned by several travellers 

 (Blakiston, A. J. Little), and of which I especially desired 



* See mite, p. 165. I regret not to be able to make use of the notes on 

 Chinese lishes in ' La Pisciculture et la Peclie en Cliiue par P. Dabry de 

 Thiersant,' as the figures as well as the accompanying notes are the work 

 of persons not conversant with the rudiments of descriptive ichthyology, 

 and as likelv to lead to misconceptions as to assist in the deterniiuation 

 of the species.
