Fig. 3. The forcipated jaws. 
A. The axis.

K. Flat or chisel-shaped tooth. 
Fig. 4. Represents the oral apparatus seen by looking directly down upon the head. 
The forcipated jaws are symmetrically placed, surrounded by powerful 
masses of muscles, and situated above the pharyngeal cavity. The 
pink eye is seen in front of the jaws and somewhat to one side, over- 
looking the entrance into the pharynx. 
Fig. 5. A salivary gland, highly magnified, 650 diameters. 
The gland shows the secreting cells with their central nuclei dispersed in 
a granular stroma while around what appears to be a duct, entering 
the oesophagus immediately above the stomach ; the cells appear to give 
place to a delicate granular structure, which may indicate the resolu- 
tion of the cells into the secreted matter. 
Fig. 6. Represents the multilocular stomach, with the oesophagus and salivary or 
pancreatic glands attached. 
Each loculus of the stomach has a clear nucleus on its centre, and while 
the whole cavity is a digestive sac, it is not improbable the loculi and 
their nuclei represent rudimentary hepatic caeca. 
Within the stomach are seen a Closterium and a Gonium on which the 
animalcule has fed. 
Muscular fibres may be seen passing over the stomach sunk in the de- 
pressions between the sacculi of the organ ; and attached to the fundus 
are slender muscles, which are also fixed to the lowest part of the tegu- 
mentary case of the animalcule, and serve to retract the stomach after 
displacement and regurgitation of the digested food.

the circulatory organs (A), with their attached ciliated or vibratile tags (B),
