secondary importance in front of the main gastrosplenic artery. 

 Then follow, after a considerable gap, the two mesenteric arteries, 

 which cross in the usual Lacertilian fashion *, the anterior sup- 

 plying the cfecum and large intestine. The second gives rise to 

 two main branches immediately after it has passed under the 

 first. 



Hepatic Pointed System.. — In addition to the anterior abdominal 

 vein, concerning which I have nothing to say, and the median 

 epigastric, which I describe elsewhere, the liver receives a single 

 gastrohepatic vein and a considerable series from the doi'sal 

 parietes. There appear to be none from the venti'al parietes 

 independent of the epigastric. There are, however, no less than 

 three dorsal parieto-hepatic vessels, of which two are larger than 

 the third. This system is thus more conspicuously developed 

 than in some Lizards. 



Epigastric Vein. — I succeeded in discovering only the median 

 epigastric vein in Phelsuma ; whether the others are present or 

 not, I am unable to say. This vein joins the anterior abdominal 

 posteriorly, as in most Lizards, and does not seem to be prolonged 

 further back — to the fat-bodies, for example. 



Anteriorly it joins the liver after receiving an important 

 branch from the ventral parietes. The epigastric system is, 

 furthermore, represented by two or three veins from the 

 ventral parietes, arising anteriorly to the entrance of the median ■ 

 epigastric into the liver, which do not communicate with the 

 liver, but open into the vena cava in front of it. I observed 

 a slight connection between the epigastric and one of these veins. 

 Siiprarenal Pointed System. — This system is by no means so 

 clearly marked off from the general systemic circulation as it 

 is in many Lizards. In the case of the left suprarenal body, 

 I noticed two afferent veins arising from the parietes. One of 

 these arises anteriorly from the parietes near to the middle line, 

 and may be looked upon as a portion of the posterior cardinal ; 

 the second vein arises laterally and runs at I'ight angles to the 

 longitudinal axis of the body. These vessels seem to join a 

 considerable plexus lying between the gonad and the vas deferens, 

 which plexus is also continuous with the system of the vena cava 

 through the spennatic veins. 



The azygos vein is present only on the right side, and is not 

 very extensive. 



The anterior abdominal vein gives off anteriorly on each side 

 a lateral abdominal before it unites with its fellow in the middle 

 line. 



Tarentola annularis. 



The vascular system of this Gecko, so far as I have been able 

 to examine into its details, does not show wide differences from 

 that of Phelsuma. There are, nevertheless, a few facts to which
