nourishment of the horny claw which originally ensheathed the bone. The 
proximal end (fig. $a) is divided as usual by a median vertical ridge 
into two facet tes, which are nearly flat. For comparison with this specimen 
one of the finest known Megalosaurian claws from the English Wealden is 
shown in fig. 4. The latter is shorter and stouter than the former, and its 
deep lateral groove extends further backwards; but the general resem¬ 
blance between the tw r o fossils is very striking. 
It is to be hoped that further diligent search may be made at Cape 
Paterson to recover the vertebrate fauna indicated by these fragmentary 
fossils. The discovery of the terrestrial and freshwater life of the Aus¬ 
tralian region during the Jurassic period would supply a most important 
deficiency in palaeontological knowledge.

REPORT ON GRAPTOLITES. 
By T. S. Hall , M.A. (Melbourne University). 
(Nos. 1178-1406. Collected by W. H. Ferguson.) 
From Dunolly. 51J chains north of the north corner of allot. 18, sec. xi., 
parish of Painswick. 
Though this large series of specimens, collected by Mr. W. H. Ferguson, 
is for the most part fragmentary and ill-preserved, yet sufficient are identi¬ 
fiable to enable the age of the beds to be determined.

The remaining specimens are not identifiable. 
The age of the beds is clearly Lancefieldian, for, in addition to the 
typical species occurring, there is an absence of Bendigonian fossils. One 
point may be drawn attention to, and that is that Bryograptus is represented
