vesicular zone being three-quarters of an inch, and that of the 

 septal area one and a half inches. 



As compared with the British ^c^i'noc^/s^ts cylindricnm, Lonsd.sp., 

 our form appears to have a larger central septate area. 



Loc. and Horizon. — Langmorn Creek, Raglan, twelve miles 

 west of Keppel (The late J. Smith, Colin. Geol. Survey Queensland, 

 Brisbane). Raglan Limestone (Middle Devonian). 



Family— CALCEOLID^. 



Genus — R h i z o ph v l l u m, Liudstrom, 1865.

Obs. — A rather fine example of this genus, in all prol^ability, 

 although the structure as exhibited in the truncated base, and 

 along the calicular edge is dense and non-vesicular. This would 

 place the fossil nearer Calceola, were it not that the latter has a 

 pointed base, and is said to be free. The specimen is, unfortu- 

 nately, an only one, and the calice is so infilled with irremoveable 

 matrLx that a more detailed examination cannot be made. In 

 shape it corresponds with the mature condition of R. interpunc- 

 taturn, De Kon., with ill-preserved traces of exothecal imbricating 

 laminae on the lateral angles, between the convex upper and flat 

 under surface. The base is truncated, probably by fracture from 

 the original attachment, and certainly shows no sign of any 

 epithecate covering, but a dense homogeneous appearance. 



This coral is larger than any individual of R. interpunctatum I 

 have seen, but resembles it in outline. In the absence of inter- 

 mediate forms it is not advisable to unite it with that sjDecies, but 

 simply to figure it for future reference. 



Dr. G. Lindstrom has advanced* the extraordinary opinion 

 that R. interpunctatum, as figured by De Koninck, is but the
