the figure is the oesophagus which is seen to have flve large folds. 
The small oval body indicated adorally to each tooth represents 
the Polian “vesicle“. 32 /i. 
2. Lantern of a specimen, 7 mm long, in side view. S2 /i. 
3. Dental pyramid from a specimen, 7 mm long, seen from the inside. 
To the right the brace and compass have been removed, so as to 
show the shape of the epiphysis (e), which has remained in situ. 
The left side shows the brace (or rotula) (b) and the compass pieces 
(c) in situ. The tooth (dl is seen in its place. 32 /i.

surface for the attachment of the interpyramidal muscle. The epi¬ 
physis has been removed, a corresponding impression being seen 
at the upper end of the pyramid. From a specimen, 7 mm long. 32 /x. 
5. Oral region of a specimen, 9 mm long, from the inside, showing 
the half absorbed remnants of the lantern. 12 /i.
