iously contrast with the fine bristles of the anterior side. The post- 
erior spines are as long as or generally even longer than the fol- 
lowing segment. 
The caudal appendages are siender, and long, about twice 
as long as the protopodite of cirrus VI, with 12 segments. They 
have only few hairs. 
The penis is stout and short, only about half as long as cir¬ 
rus VI; it is annulated and carries some few long hairs; at the

distal end a tuft of hairs is found. The penis is rapidly tapering 
towards the distal end. 
The labrum has a row of broad, and low, tuberculate dent- 
icles along its interior side. It is not bullate nor very prominent. 
The mandible (Fig. 35) has four strong teeth, the fourth at 
its lower angle. Only the third tooth is armed with small denticles 
at its lower side. The second tooth occupies the middle of the 
cutting edge. A dense growth of finer hairs covers the lower part 
of the mandible from the excavation between the first and the sec¬ 
ond tooth downwards. 
The maxilla has a strong spine at its upper edge; between 
this and a slightly pronounced notch a smaller spine is present. 
Below the notch the cutting edge is densely armed with spines.
