Fig. 11 Semi-diagrammatic graphic reconstructions (from frontal sections) 

 of the liver veins, as seen from above, of three Acanthias embryos. The hepatic- 

 portal veins are represented in solid black, the hepatic veins and sinus venosus 

 in heavy stipple and the hepatic parenchyma in light stipple. In figure 12 A, 

 the connection between the liver and the foregut and the upper parts of the lateral 

 hepatic pouches are represented as cut away dorsally. A, embryo 15 mm. long 

 (H.E.C. 230); B, embryo 20 mm. long (S.C. 31); C, embryo 41 mm. long (H.E.C. 

 371). H.p., right lateral hepatic pouch; St., stalk connecting liver pouch with 

 foregut above; S.v., sinus venosus; V.h.d., right hepatic vein; V.h.-p.d., tight 

 hepatic-portal vein.
