MteIOLITHES ? QUEENSLANDEUSIS, Sf. 710V. 
Sp. Char. Polyzoarium small, with the branches oval, or more or less flattened. 
Cells very small, round, arranged in vertical series, alternate or sub-alternate, their 
margins rim-like or a little oxsert, and somewhat more than their owm diameter apart; 
intercellular surface vermicular striate, the striae anastomosing above and below each cell- 
aperture, or they are at times sub-parallel to one another. 
Ohs. This little fossil, which occurs in fragments on the surface of weathered 
limestone, has given me much trouble, but accords better with Eichwald’s description of 
MjjriolitJies than with any other similar genus with which 1 am acquainted. I have, 
however, failed to detect any intermediate capillary tubes. It is allied to M. ononticola, 
Eichwald, from Carboniferous Limestone of the Oural, but differs in its method of 
branching, and in the form and arrangement of the cells. I have not yet examined 
sufEcient material to warrant my assigning it to any particular family.

Ohs, On tlic publication of tbo “ Catalogue of Australian Possils,” I, in common 
^'ith others, believed this to be only a form of the ordinary D. sacculus, so characteristic 
Carboniferous rocks, hut the acquisition of other specimens now leads me to a 
‘Contrary opinion. The shell generally is more attenuated and higher towards the 
^Jnbonal region of the ventral valve, much more overcurved, and the shoulders longer and 
'J^oro pronounced. The foramen is vastly larger in comparison with the size of the 
much more truncate and horizontally placed. The dorsal valve is arched in a 
p^cator degree, becoming in some examples snh-angular towards the umbo. Lastly, the 
^teral margins of the united valves are always more sinuated. For the reason now 
I believe K. hasiata, Sby., and D. cymheeformis should he retained as separate 
species. With the exception of the unusually large specimen of K. hastata figured by 
* Also reported by Mr. Smith, from the Limestones at Raima (Rockhampton District) and Raglan 
Cnrtis District), hut I much (luestion its occurrence at the latter locality. (R. E. Junr.)
