88 Mr. J. Miers on the Menispermacese. 



duce the point of the dissecting-knife along the peripheral line 

 of suture, when it is easily separated into two valves, leaving the 

 kernel in an entire state : we thus see the true form of the cell, 

 its position with regard to the condyle, and the mode of attach- 

 ment of the seed, the embryo and the albumen, if present, being 

 thus obtained whole and uninjured. 



In the herbarium of the late Dr. Lindley, I found an Austra- 

 lian plant, collected in Capt. MitchePs exploring expedition, 

 which may be considered a second species of this genus : this 

 has enabled me to render the generic character more complete.

The type of this genus is a plant from Australia, the Cocculus 

 Moorii of Dr. Mueller, which Messrs. Bentham and Hooker 

 referred to a well-known Indian species, Pei'icampylus incanus ; 

 and in my description of that species I have alluded to the great 

 discrepancies existing between them. It differs from that genus
