The external leaf-crown is composed of about 40 narrow and pointed 
leaves; the elements of the internal leaf-crown are more conspicuous, 
the latter consisting of 30-34 long and somewhat refractive leaves, 
recalling those of C. bicoronatum Looss (Text-fig. 1 a, b). 
The mouth-capsule has a breadth of 75-100 /a and a height of 28-40 p., 
its walls are thickest near the middle, thinning down anteriorly and 
posteriorly, the shape as seen in optical section varies a little in different

specimens; extremes are shown in Text-fig. 1 A, B. There is no dorsal 
gutter, the oesophageal gland opening at the base of the capsule. 
The oesophagus is 360-420/t long and approximately flask-shaped, 
it is widest near its posterior extremity where it attains a breadth of 
110-138/4. 
The excretory pore and the cervical papillae are situated far back, 
only a short distance in front of the posterior end of the oesophagus 
and 360-500/4 from the anterior extremity of the body (Text-fig. 2 a).
