U.S.A., who has described the Hercynellas of the 
Waterlime group as being associated with a brackish 
or estuarine fauna containing eurypterids and pod- 
shrimps, and therefore differing considerably from the 
Victorian occurrence.—R. Etheridge, jun.: Reptilian 
notes. (1) The. identity of Megalania (oat Varanus) 
prisca, Owen, with WNotiosaurus dentatus, Owen. 
Some vertebre, limb-bones, dentary, and tooth from 
King Creek, Condamine River, in the Australian 
Museum, confirm Lydekker’s conjecture of the 
identity of these two forms. (2) Megalania prisca. A 
cave fossil from the Wellington Caves Reserve. Re- 
mains of this lizard have now been recorded from 
fluviatile, spring, and cave deposits. (3) An opalised 
reptilian dentary from Lightning Ridge, Walgett, of 
Cretaceous age, described as Crocodilus (? Botto- 
saurus) selaslophensis,
