Holotype : SpcciTiion figured Hill, loc, cit., text-fig. 10, in the Collection of 
the Univ'ersity of Western Australia, from the Permian of the creek half a mile 
west of Callytliarra Spring, Wooramel River, W.A. 
Diagnosis : Slender Cladochomis^ with eorallites widest at the calical 
rim, which is 3 or 4 mm. in diameter, and with 18-20 faint longitudinal stria- 
tions on the epitheca. 
Rctnarks : Tlio specimens previously described were reptant portions of 
eoralla, but 1 now Inive fragments of erect branches from the Callytharra beds 
near ( ^allythaj’ra Springs. The species has much slenderer pi’oportiona than 
the later C. nicholsoni, and the longitudinal striation on its opitheca has not been 
noted in any other spin-ies.
