slenderer, in having a shorter and more ventricose brain-case and a 

 much longer and slenderer nose, and also in the tubercular grinders 

 being broader and rounded on the inner side, and in the hinder of 

 the two being larger and more like the penultimate both in size and 

 form. In some respects the skull approaches Eapleres; but the 

 nose is broader and not so slender, and small as compared with the 

 brain-case, and the teeth are much more fully developed. 



Fossa d'aubentonii. (Plate LXXIV.) 



Brown or reddish, closely grizzled with an abundance of white 

 hairs, with four rows of more or less confluent black spots on each 

 side of the back, a few black spots on the hinder thighs. The chin, 

 neck, and belly whitish, more or less obscurely spotted.

There are two perfect specimens in the British Museum, one 

 much darker than the other. In this specimen the rows of spots on 

 the sides of the centre of the back are all united into a narrow black 

 streak, and those of the second row are united in a similar manner 

 on the first half of the back ; the underside of the body is 

 yellowish grey without any spots ; and the spots or rings of the tail 

 are very obscure. The second specimen has much more distinct and 

 larger spots both on the body and the tail ; but only the spots of the 

 back of the neck and shoulders are united on the left side, while the 

 spots of the upper series on the right side are united in lines. 



3. On the Act'memys marmorata of Mr. Lord, from British 

 Columbia. By Dr. J. E. Gray, P.R.S. &c. 



[Eeceived October 17, 1872.] 



Mr. J. K. Lord has presented to the British Museum a young Ter- 

 rapin, which has been mentioned in his ' Naturalist in British Co- 

 lumbia' as " Actinemys marmorata, Agnss., the Western Pond-Turtle." 

 He says, " I obtained these Turtles at Walla-walla, iu the month of 

 June. They had left the streams, and were wandering about in the 

 grass to deposit their eggs. Apart from the egg-season it is a most 

 difficult matter to catch them. I have seen them in nearly every 

 lake and pool east and west of the Cascades. They are also 

 common on Vancouver Island." (Lord's ' Naturalist in British 

 Columbia,' ii. p. 301.) He gives a reference at the bottom of the 

 page as if it were also mentioned in vol. i., but does not give the 

 page, and I cannot hit upon it. It has no resemblance to the young 

 specimen figured by Professor Agassiz as Actinemys marmorata 

 (t. 3. figs. 5-8), and certainly is not the Emys nigra figured and
