Animal.—Yellow ochre, spotted with dark purple, sole of the foot. yellow. — 
(sophagus long and narrow, suddenly expanding into the stomach. 
The intestine, starting a little above the fundus of the stomach, passes 
anteriorly to the left, crosses over to the right, bends backward, and again 
crosses over the stomach to the left, and, having reached the fundus, turns 
sharply forward as a rectum to the anus. The hepatie ducts enter the 
fundus of the stomach. The salivary glands open into the buccal mass, 
which is of a blood-red colour, while the salivary glands are yellow. The- 
stomach is pale yellow, with a dead white cecum at the cardiac end. The 
- liver is yellow-brown. The penis is large and thick, with an orange gland 
at the end. The ovotestis is yellow-brown, the hermaphrodite duct blue- 
black, the albumen gland and uterus pale yellow, and the spermatheca red. 
Numerous particles of calcite are found about the reproductive organs, 
Hab. Dunedin; Banks Peninsula ; Wellington; and at the Chatham 
Islands. 
Sowerby originally gave Tasmania as the habitat, but it is not men- 
tioned in the Rev. J. Tenison-Wood's Census of Tasmanian Shells. Reeve 
gives New Zealand as the locality. The identification of S. scutellum with 
this species is due to Dr. E. von Martens; I have not seen Deshayes' 
description. 
SIPHONARIA AUSTRALIS, Plate XVII., figs. x to c. 
Siphonaria australis, Quoy and Gaimard, Voy. Astrolabe, Zool. ii., p. 829, pl. 25, 
figs. 32-34 (1833) ; Gray, Figures of Molluscous Animals, pl. 76, fig. 5. 
Shell ovate-oblong, rather conical, with numerous unequal rather un- 
dulating ribs; apex posterior, not uncinate. Exterior reddish-brown, the 
ribs white; interior liver brown, the margin generally marked with white 
at the termination of each rib. Length 75; breadth :5 to :6; height E 
*25 inch. B 
Dentition, ar Jaw arcuate, of equal thickness throughout, — 
rounded at each end, concave margin papillate, remainder of surface 
obliquely cross striated in two directions. Central tooth rather narrow, E. 
its length being nearly three times the breadth of the base. Laterals about E 
19, they and the marginals much like those of S. obliquata. 
_ Animal pale-yellowish, speckled with black on the sides of the foot and 
head. Alimentary system like the last species, but the esophagus is short 
and passes gradually into the stomach, which is yellowish-white. The liver 
is pale yellow. The penis is long and narrow, the gland pale yellow. The 
ovotestis is brownish-yellow, and the spermatheca narrow. _ 
Hab. Abundant on rocks in the south as far as Banks’ Peninsula ; 
rare in Cook’s Straits, Quoy's specimens were obtained on the roots of 
kelp. -
