468 MR. F, E, BEDDARD ON THE | Nov. 28, 
interna,” does describe such vessels as I have dealt with above ; 
but his descriptions do not tally exactly with the facts which 
I have observed, and it is not clear to what species or even to 
what genus his observations refer. 
There are also ventral parieto-hepatic veins connected with the 
epigastric vein, which are but slightly dealt with by Rathke * and 
not figured by Jacquart ?. These are most conspicuous in the case 
of the right lobe of the liver. They are partly directly connected 
with the right epigastric vein and partly enter the ventral parietes 
separately. There are three of these vessels, which arise from a 
slender superficial vein running along the ventral surface of the 
liver and continuous with the anterior abdominal vein posteriorly. 
The first of these ventral parieto-hepatic veins (?. e., that nearest 
to the breast) divides into three branches, of which one joins the 
epigastric and the others plunge into the ventral parietes 
separately. The second vein is at about the middle of the liver 
and joins the epigastric. The third is really given off from the 
anterior abdominal before it enters the liver and joins the 
epigastric. 
On the left side there is only one of these veins corresponding 
in position to the stronger and middle one of the three on the 
right side. 
(3) Votes on the Vascular System of Ophisaurus. 
The most recent memoir known to me which deals with the 
blood-vessels of Ophisaurus apus (Pseudopus pallasti) is by 
Prof. Hochstetter =, whose notes refer entirely to the venous 
system of that Saurian. Some earlier works upon comparative 
anatomy, such as those of Siebold and Stannius §, contain various 
facts relating to the blood-vessels. But I find that the recorded 
knowledge of the course of the arteries and veins in this Lizard 
is practically confined to Rathke’s extensive memoir|| and to 
Hochstetter, and does not enable us to draw up anything like a 
complete account of the vascular system. I have therefore 
thought it desirable to utilise a thoroughly injected example of 
this Lizard, which was treated immediately after death, for the 
purpose of a further contribution to the knowledge of the vascular 
system in Lizards, which matter has been for some time occupying 
my attention. 
The origin of the several aortic trwnks from the ventricle is as 
in other Lacertilia and a detailed description of the same is 
therefore unnecessary here. The carotids show certain pecu- 
liarities which are worth noting. The carotid artery arises from 
the carotid arch just where it turns over to join the systemic 
arch of its own side in a fashion which does not appear to
