the Great Glacier formation and the Quaternary and Recent periods 
will interest the glacialist and anthropologist; the latter section 
treats of the first appearance of man in the island, the occurrence of 
Moa bones and the extinction of the Dinornithide, and a notice of the 
deposits at Glenmark, which have yielded the largest quantity and 
variety of Moa bones. 
This work will form a useful guide to the geological structure, 
economical products and general character of the provinces described, 
while much interest and instruction will be derived from the vivid 
descriptions of the grand scenery of the Southern Alps, whose 
present physical features have chiefly originated or been greatly 
modified (see p. 173) during the great Ice Period, when glaciers far 
more extensive than the present ones descended and spread over the 
lower regions (as shown in Map, pl. ii.), disintegrating and denuding 
the contorted and elevated crystalline rock and other formations, 
scouring out the valleys, and transporting the morainic matter far 
and wide—the extensive distribution of which ‘fully indicates the 
former more powerful and long-continued action of the Post-Pliocene 
glaciers. “The action of the giant ice ploughs, as we may call 
these glaciers, has essentially assisted in preparing the lower regions 
for the use of man, since by it the narrow valleys have been 
widened, the rugged mountains rounded off, and large plains have 
been formed” (p. 189). The report also contains a geological map 
and numerous sections, illustrative of the third part, as well as a 
series of lithographs, representing the finest scenery in Canterbury 
and Westland. J. M.

1. “Supplementary Note on the Vertebre of Ornithopsis, Seeley 
(=Eucamerotus, Hulke).” By J. W. Hulke, Esq., F.R.S., F.G.S. 
The author in this communication describes several cervical and 
trunk vertebre of this remarkable Dinosaur. The former are cha- 
racterized by great length; the anterior articular surface is strongly 
convex, and the posterior correspondingly hollow. In place of the 
side chamber characterizing the trunk vertebral centra, is a long 
shallow pit. An upper and a lower transverse process are given off 
from an upper and a lower plate, which project from the side of the 
centrum above the pit, and these are connected by a short, forked 
cervical riblet. The neural arch is dwarfed, and there is no spinous 
process, and no zygosphenal and zyganteal mechanism. The struc- 
ture of these vertebra indicates a long, mobile, and light neck. In 
the trunk the convexity of the anterior articular surface lessens in 
passing from the neck to the loins, the anterior ball gradually sub- 
siding till the great articular surface becomes plane, the posterior 
surface retaining, however, a slight hollowness. The trunk vertebra 
have superadded to the ordinary articular processes a mechanism
