DISTRIBUTION OF AUSTRALASIAN VOLUTES 
13 
I7.-VOLUTA VOLVA— Chemnitz. 
Has also a wide distribution, and is f ound not onl on the 
Western coast, but extends beyond the Nbrth-west Cape, where 
specimens differing little from those of Swan liiver are abundant. 
It is a white or cream coloured shell, and in some instances bag 
a few faint lines on the sutures, which never appear on the body, 
except on what I may term the reverse of the shell, near the 
columella. 
18—VOLUTA RETICULATA— Reeve, 
Is a beautiful and much rarer Volute than Norrisii. Its ranee 
is about from the North of the Ashburton River, to the Westward, 
to the neighbourhood of Bannangarra Creek on the eastward, a 
distance of about four hundred miles. It seems to attain its 
largest growth about lien Ism Creek. The crew of the 'Argo, 
which visited Camden Harbour in 1869, did not bring any of 
these Volutes; and it is probably very scarce there, or may 
not extend so far Last. I have several varieties of this fine 
Volute, varying in length from three to five inches, and from a 
dark fulvous chestnut to a pale grey colour, of a triangularly 
reticulated pattern. 
The pattern of A . reticulata , although always a network 
differs in specimens from different localities; a band of a 
darker shade alternates with the groundwork, but in a few rare 
specimens I have, a light network covers the whole of the shell. 
The specimens from the farthest West (this shell extends to the 
North-West Gape) aic the smallest — those in the immediate 
neighbourhood of Tien Tsin Creek are very large, The animal is 
of a beautiful brown colour, varying as the shell is light or dark 
brown, with continuous but irregular rows of whitish yellow lines. 
19.—VOLUTA REEVII—Sowerbv. 
There can be no doubt about this being an Australian species, 
although its exact habitat is not known; I have no doubt it will be 
found to be on the north-west coast of Australia. So closely is this 
species allied to the reticulata, that it was considered at first by 
Sowerby only as a variety of that species; but subsequently lie 
created it into a distinct species, and defined it as being a broader 
shell than V. reticulata . 
20.—VOLUTA ELLTOTI—Sowerby, 
The most purely Australian of all North-west Volutes, evidently 
a continuation of / alula zebra , of New South Wales, V. Angasi 
of Victoria and Tasmania, and V. undulata of South Australia 
commences at the North-West Cape, in Exmouth Gulf, and 
although the first specimens were said to be from Shark’s Bay, on
