Animal. — Yellow ochre, spotted with dark purple, sole of the foot yellow. 



(Esophagus long aud narrow, suddenly expanding into the stomach. 

 The intestine, starting a little ahove 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 hepatic 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 caecum 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. 



Hah. Duuedin ; Banks Peninsula ; Wellington ; and at the Chatham 

 Islands. 



Sowerby originally gave Tasmania as the habitat, but it is not men- 

 tioned in the Eev. J. Tenison-Wood's Census of Tasmanian Shells. Eeeve 

 gives New Zealand as the locality. The identification of S. scutelhtm with 

 this species is due to Dr. E. von Martens ; I have not seen Deshayes' 

 description. 



SlPHONARIA AUSTRALIS. Plate XVII., figS. E to G. 



Siphonaria australis, Quoy and Gaimard, Yoy. Astrolabe, Zool. ii., p. 329, pi. 25, 

 figs. 32-34 (1833) ; Gray, Figures of Molluscous Animals, pi. 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 

 •25 inch. 



Dentition, 36 ~g~-. 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, 

 its length being nearly three times the breadth of the base. Laterals about 

 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 oesophagus 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.
