 nent, extending to the 

 end of lobes. A pair 

 of trifurcate plates be- 

 tween median lobes.

 furcate plates between median and lateral lobes. In the depression after 

 the lateral lobes are three pairs of large plates with a number of teeth, the 

 third is largest, and usually has six teeth. Very few spines ; one at the 

 base of each lobe, another shortly after the last plate, and one quite 

 distant along the margin. Dorsal pores prominent. Five groups of cir-
