Hab, Coast of New Holland, north of Swan River Settlement. 
This beautiful new Volute somewhat resembles the Voluta pallida 
in form, and is of nearly the same ground tint of colour ; here, how- 
ever, the resemblance ceases, it being entirely covered with a fine 
brown net-work, with two broad bands formed by a rich amalga- 
mation of the net-work. The most striking feature of the shell is 
in the upper part of the whorls being vividly ornamented with a 
close-set row of undulating flames of rich brown running down from 
the sutures, and the enamelled lining of the aperture is of the same 
uniform rich brown. Of the two specimens just imported in H.M.S. 
Beagle, one is in the collection of Thos. Norris, Esq., of Redvalves ; 
the other in that of J. Dennison, Esq., of Woolton Hill. There is a 
bad specimen of this Volute in the British Museum, and another in 
the collection of William Metcalfe, Esq. 
Prof. Owen then read the second and concluding part of his me- 
moir on the Dinornis*. 
The arrival of the second box of specimens of the bones collected 
by the Rev. W. Williams in Poverty Bay, New Zealand, which had 
been placed by Dr. Buckland in Mr. Owen’s hands, had enabled him 
to confirm his former account of the generic characters and ordinal 
affinities of the apparently extinct Dinornis, and also to distinguish 
renains of five species of that genus. 
The bones of the foot, and especially the tarso-metatarsal bone, 
established three distinct species, the largest of which the author 
proposed to call Dinornis giganteus; the next in point of size he 
termed Din. struthoides, and the third Din. didiformis. The com- 
mon generic characters of the tarso-metatarsi of these species were 
first pointed out, and then their specific differences of proportion and 
figure. The maturity of the different-sized bones indicating the 
above species was demonstrated by reference to the long retention 
of immature characters in the same bone of existing Struthionide, 
and by the fact of a tarso-metatarsal bone of a half-grown Dinornis 
giganteus manifesting the same incomplete coalescence of its primi- 
tively distinct elements ; showing that the Dinornis, like the Ostrich, 
had a tardy ossification of the skeleton, as compared with birds of 
flight. The tibize were next described; one of these, belonging to a 
mature bird, established a species smaller than the Din. didiformis, 
and which, from its similarity of stature to the great Bustard (Otis 
tarda), Prof. Owen proposed to call Dinornis otidiformis. The
