The muscles, oesophagus, mouthparts, bristles and their arrange- 
ment etc. were carefully worked out and drawn, the stomach 
was put in in diagrammatic outline. The oral cirri were given 
transparent and their muscles omitted, the muscles in the other 
cirri were likewise omitted. The dorsal line of the body is also 
somewhat diagrammatic, this portion is actually imbedded in the 
mass of the disk. 
The animal is given transparent, but the muscles etc. of the 
left side are omitted. 
The outline of the mantle, lips, neck, knob, and disk and of 
the ovaries were added diagrammatically. The disk which is at 
right angles to the plane of the body was pressed a trifle towards 
one side so as to show the insertions of the muscles from the 
body. All details of the mantle and the disk were omitted in 
order not to complicate the drawing. 
I First thoracic segment. J/ Unsegmented portion of the thorax 
which may correspond to one or several segments. 1/—6 Post- 
discal segments. 7—9 Base-plates for the cirri, representing the 
remnants of the last three thoracic (?) segments.
