Of the above forms the following are worthy of especial note : — 
Sphenotrochus emardatus has a, remarkably extensive range, being 
found alike in Balcombian, Janjukian, and Kalimnan strata. 
Ditrupa cornea, var. wormbetiensis is especially typical of Janjukian 
beds ; it is a characteristic and abundant fossil in the polyzoal rock 
of the Mallee Bores and of the upper limestones of the Spring Creek 
series, and so far as I am aware, only a single specimen has occurred 
in the Balcombian, at the toji of the series, at Muddy Creek. The 
brachiopod provisionally referred to Terebratula (?) aldingae is a 
cast, which, by its compressed shape and outline, is nearest that 
species, only occurring in Janjukian strata ; the squarish anterior 
is matched very closely by specimens in the Dennant collection ; 
and the only other species with which it could be compared is T. 
vitreoides, T. Woods, also a Janjukian form. Pecten praecursor is a 
specially characteristic Janjukian form. P. flindersi is also of 
similar age, being found at Aldinga. 
From Mornington towards Frankston, and over the hinterland, 
thick deposits of fine and coarse sands, often ferruginous, are largely

overspiead. The age of this series is doubtful, being unfossiliferous, 
but the lower portion is undoubtedly of Janjukian age, as shown
