 zone always convexly angled outwards, Ijut those in the outer 

 moiety imperfect and variously' directed. Rugte corresponding 

 to the septa. 



Ohs. — iSpecimens in Mr. Sweet's Collection enable me to give a 

 more precise diagnosis of the Cyatlwphyllum occurring in the 

 Devonian beds near Townsville, than did the oi'iginals collected 

 by Mr. R. L. Jack. I now propose for it the name of C. SweMi. 

 This is a form of no great outward distinctive features, liut 

 possesses a very remarkable long counter septum. The septa 

 within the dissepimental zone are direct, although slightly flexuous, 

 and do not evince any curvature until this zone is passed, and 

 even then not all of them. One group in particular, one of the 

 alars, curves round the supposed fossula. A peculiar character, 

 not readily explicable, is a l^ifurcation of the septa within, and 

 slightly without the dissepimental area, unless it be an aborti-\'e 

 attempt at dissepimental growth. The longest septum, which I 

 take to be the counter septum, is on the ventral or concave side. 



No definite theca is present, but the thickened proximal ends of 

 the septa form the outer wall, in places nearly one millimetre 

 thick.
