ON THE ANASPIDACRA, LIVING AND FOSSIL. 569 
The first thoracic limb is a powerful raptorial organ of the 
structure shown in text-fig. 53. The next two limbs were 
rather small and fairly stout, but the succeeding five thoracic 
endopodites are very long and slender. Fritsch denies that 
any exopodites were present, but it may well be contended 
that the fine striz figured by Jordan and v. Meyer springing 
from the bases of the thoracic limbs represent the hair-like 
sete present on slender exopodites. 
The abdominal appendages, according to Fritsch, are flabel-

late in structure, but Jordan and v. Meyer made them out to 
be setose. 
Fritsch gives a very finely detailed drawing of the telson 
and uropods (text-fig. 55). 
The telson was an elongated oval, with sete on its posterior 
lateral margins, and two long and two short sete at the hind 
end. The outer ramus of the uropod was about equal in 
length to the telson, and had a row of six short sete and one 
enlarged spine on its outer border. Fritsch figures a con- 
Spicuous sphere on the inner ramus which he interprets as 
an otocyst.
