inner surface of the skin in this oie en just above the extra- 
coelomic kidney is not smooth owing to the outer surface of 
the organs which it covers set irregular. It shows numerous 
projections of fatty tissue which fills up the interstices or

kidney. 
2. Saccobranchus fossilis.—The remarkable — in 
the disposition of the liver and the kidney described above is 
also to be found in Saccubranchus fossilis. The arrangement 
in the two fishes is exactly alike. 
The length of an adult Saccobranchus jossilis varies from 
12 to 13 em. and the breadth is a little more than 2cm. Th 
lobes of the liver and the kidney are accordingly much smaller 
in size. The coelomic liver lobes of Saccobranchus fossilis are
