A single specimen of the snI>-conical variety was obtained. 
When coni])ared with the Cretaceous Annelids hi tlie Tennant Collec- 
tion, now in the Western Australian Museuin, its resemblance to a 
specimen of .S'. ampuUacea was so marked that identity was suggested 
at once. Tiie specimens of Etlieridgi' ’s .S', grcgarea from Gingin 
were then compared Avitli the English specimens and found to fad 
wi+hin the range of vailation recoginsinl in that specii's, 
Terebratuiina ovata Kth bl. . 
Terebyatiilina ovata. Etli. fil. (1913), ]i. 14, ]>1. IT, figs. 18-19. 
Three sp.ecimens of this small shell were obtained, the collec- 
tion also contains several larger individuals with simple echinate 
costae which may prove to be the adults of this species.

This is the commonest fossil at Kound Hill, it is, if anything

perfect state of preservation.

After the preceding this is the most plentiful Rrachiopod in 
the zone on Eoiiud Hill, the specimens are generally in good 
condition, 
Magas mesembrinus Eth fil.

Eather rare, but more abundant than at Gingin. 
Undetermined Brachiopods. 
These include several forms not yet met Avith in the chalk at 
Gingin Tlie abundance of Brachiopoda in the zone on Round 
Hill Avould almost Avarrant the designation Braehiopod Band.

Ostrea sp Eth. fil. (1913), p. 17, pi. II, figs. 19-21. 
Remains of small Ostrea spp. arc very common, they are usually 
fragmentary. One or tAvo specimens seem to resemble Etherido-e^s 
species ''a'" (ib. p. 17, pi. IV, figs. 8-9).
