very characteristic. The femur is stout and straight, its 

 length is not as great as that of the coxal region. The 

 first tibia is about equal in length to the femur, is some- 

 what narrow at its proximal end but expands more towards 

 the distal end. The femur and tibia are armed with small 

 scattered spines. The tarsal joint is small and bears ven- 

 trally a series of small spines ci'owded together; dorsally 

 there is a single larger spine. The propodus is stout and 

 curved. It is armed with a stout claw with two well- 

 developed auxiliary claws. Dorsally, it bears a number 

 of short spines. Ventrally, the heel is not sharply marked 

 off, but this region is indicated by the possession of four 

 or five short but stout spines, while the sole possesses about 

 twelve, which are much more minute.
