„ Ols. Several Ithynchonellw from the Fanning liorizon have given much trouble 
*’0® the state of their preservation, which i.s unsatisfactory, hut they appear to corres- 
pond better with the characters assigned by Dr. Davidson to Von Buch’s species than 
to any other. The shape of the shell appears to be much the same, and the bending 
own of the front margin of the dorsal valve is quite ajiparent in all the specimens. 
*1 submitting the specimens to Dr. Davidson he replied that “ the Bhynchonellas seem 
° be very close to the B. primipilaris of the Devonian.”

Ols. This is an exceedingly variable species, sub-orbicular, circular, or broad- 
°i'ate ; the dorsal valve with or without a mesial fold, and sometimes even with a sinus ; 
the ventral valve evenly gibbous, or with a slight fold, and ornamenled or not with 
®bght longitudinal ribs. 
^ Amongst the (Queensland examples is a specimen in which both valves possess 
^ ®esial fold, and the front margin is a good deal sinuated; whilst in otheis the 
oth'^^^^ ^olve is quite plain; another in which the fold is faintly ribbed; and again 
in which the dorsal valve is itself without a fold. As regards form, we are 
j with the long suh-orbicnlar outline, the broad-ovate condition, and one 
^ ividual in which the shape is almost circular. Indeed, the various outlines accord so 
with those of European specimens as to be remarkable, the only difference 
^ ^ceablo being the less development of the area in the Australian examples, and the 
. ODsequent concealment of the fissure ; this is, however, perhaps assisted by the greatly 
central umbones. A fractured example of the ventral valve shows the septum, 
tlie*^ of the genus, which is large and well developed. The shelly plates of 
same valve had no great degree of divergence.
