In Fig. 3 the hepatic portal system in Necturus has the branch 
passing through the pancreas and spleen unusually large. The position 
of the small spleen is close to the body wall instead of being near to 
the stomach. From the splenic vein a broad, short branch passes 
directly to the body wall where a number of short, finger-like branches 
extend in all directions for a relatively short distance. I was unable 
to determine that these branches from the hepatic portal system were 
associated with other veins or arteries, in the body wall.

The conditions shown in Fig. 4 is that of two double spleens 
in Necturus, one found in a female, the other in a male. In the male 
the two parts are entirely distinct, while in the female the division 
is not quite complete.
