358 DR. J. C. COX ON NEW AUSTRALIAN SHELLS. [May 13, 
8. On three new Species of Australian Marine Shells. 
By Jamzs C. Cox, M.D., Sydney, New South Wales. 
(Plate XXVL) 
CypR#A THATCHERI, n. sp. (Plate XXVI. figs. 1, 1a.) 
Shell pyriformly ovate, rather thin, markedly ventricose, base 
almost flat; sides steep, deeply notched; anterior end contracted 
and prominent; posterior end produced, narrow; aperture almost 
straight, except in front, rather open; teeth thick, obtuse, faint 
purplish white, about twenty-four on the outer edge, and confined 
to the margin of the aperture; on the columellar side the teeth are 
short, oval, blunt, and larger, becoming almost obsolete in front ; 
cream-coloured with a cinnamon tinge, smooth and polished, varie- 
gated with rather large orange-brown spots of irregular size and irre- 
gularly distributed; the cinnamon tinge is slightly deeper at the 
ends; base white and perfectly smooth, sides light; extremities 
rather recurved ; interior pinkish white. 
Length 3 inches, breadth 142, height 144. 
Hab. Dampier’s Archipelago, West coast of Australia. 
The two specimens of this beautiful species now before me, one 
of which I send to be figured, were obtained by Mr. C. R. Thatcher, 
from a fisherman who took them at the locality above recorded, 
about ten years ago; and, so far as I know, no other specimens 
have yet been found. The two specimens are exactly alike in every 
way, and in a fine state of preservation. The surface of the shell 
is uniformly covered with a smooth shining enamel, showing no trace 
of a dorsal opening. 
VoLuTa HARFORDI. (Plate XXVI. figs. 2a, 20.) 
Shell elongated, ovate, thick ; spire acuminate, short, apex papil- 
lary ; whorls smooth, slanting, strongly excavated or channelled at 
the suture; columella four-plaited, pinkish white; aperture elon- 
gated, lip simple; pinkish white, shining, longitudinally striated by 
fine waved brown lines, ornamented by four bands of squarely elon- 
gated orange-brown spots on the body-whorl, and by a band of round 
spots of the same colour about the centre of the shell, between the 
upper and lower rows of squarely elongated markings. 
Length 1,3, inch, breadth H, height =%. 
Hab. Wreck Reef, near Lady Elliott’s Island. 
This species in general aspect much resembles Voluta maculata 
of Swainson, but is at once distinguished from that or any other 
species by its channelled or excavated suture, elongated striation, 
and regular squarely elongated orange-brown markings. 
VouuTa sciaTerI. (Plate XXVI. fig. 3.) 
Shell pyriformly oblong, ponderous; spire rather short, obtuse, 
papillary ; whorls smooth, porcellanous, the last tending to be angled 
or protuberant round the upper part; columella strongly five-
