MR. F. E. BEDDARD ON THE 



[May 3, 



It is a noteworthy fact about the liver of this lizard that 

 a good many of the longitudinally running veins passing thiough 

 it appear at intervals on its surface, instead of being covered 

 throughout as is the general rule. 



The portal vein has the following affluents (see text-fig. 3, 6, c, 

 d, e, p. 13, & text-fig. 6, Spl.): — a gastric branch which really 

 belongs to the anterior abdominal system and has been already 

 referred to ; just posterior to the liver a splenic vein ; behind 

 this two veins near to each other, one of which is splenic, 

 the other gastric; still more posteriorly a large vein which

is formed of two branches, one of which is gastric, the other 

 intestinal ; behind this again another vein from the small 

 intestine joins the common trunk ; the last branch of importance 

 is one from a dilated, almost globular, region of the small in- 

 testine. The main trunk then pursues a straight course along the 

 rest of the gut.

I have a few notes only to offer upon the vascular system of 

 this Gecko, of which I have examined only a single male 

 specimen.
