 tubes, inlciiially spinose. On one side, al)out midway between the junction of the

Discofasci(jera dill'ers from Defrancia and other stipitate forms in having the 

 zotecia covering the wliole upper surface and not arranged in any definite order. 

 The interstitial tubes or pores, which are very few, are smaller but otherwise 

 indistinguishable. It is diilicult to say what the large projecting tubes represent. 

 They may possibly communicate with an internal ocx;cium, Ijut that is improbable, 

 as such a structure is luiknown among the Cyclostomata.
