Manqelia le-tourneuxiana. Crosse., Jour, de Conch., 1865, p. 425, 

 pi. 11, fig. 7. A small attenuated shell of ten whorls, Urate and obscurely 

 few ribbed, generally chocolate brown. Not common. S. and E,, and 

 S.E.A. 



Triton cutaceus. Linne., Syst. Nat., 12 Edit, p. 1217. A large ovate 

 ventricose shell, girdled with sulci and wrinkled ribs of pink color not unlike 

 human skin. A faint plait on the upper part of the columella. Ordinary 

 specimens about a decimeter long. Lamarck gives the Atlantic as its 

 habitat. All the species are so wide spread that I have no doubt of its ex- 

 tending to Australia. Kecent deep sea dredging wiU probably cause some 

 species of Triton to be abandoned, their habitat being the only reason for 

 regarding them as distinct. 



Triton spengleri. Dilhoyn, Bescrip. Oat. Recent Shells, p. 2. This ap- 

 pears to me only a variety of the above with a dilated mouth. The young 

 shells are variegated and so finely marked that I believe they have been 

 also mistaken for difierent species. Kiener thought, but probably in- 

 correctly, that this was the character of T. tranqueharicus. S.E.A. and S.H. 



Triton waterhousei. Ad. and Ang. Much smaller than T. aitaceus, but 

 difficult to characterize by any other feature. 



Triton QUOYi. Reeve. Icon. pi. 19, fig. 93. Common. A small whitish 

 shell with 4 to 5 varices, acute spire, and finely decussated outer lip, toothed 

 within. Long. 25, lat 13, whorls 7. Common in S.A. 



Triton subdistortus. Lamarclc., Vol. 9, p. 638. A larger and more 

 ventricose shell than the preceding ; ovately conical, sub-distorted, with 

 fine irregularly noduled transverse ridges ; whitish, mottled with brown. 

 Long. 68, lat. 30, whorls 7. Common. E. and V. 



Tritonidea petterdi. Brazier, 1%1Q. One specimen only from Bridport, 

 N.E. Coast, now in Melbourne Museum. W. F. Petterd. 



Ranella leucostoma. Lam., Vol. 9, p. 542. Triton leucostoma Quoy, 

 Voy. Astrol., t. 3, 546, pi. 40, fig. 3. An ovately conical shell, with varices 

 scarcely regular enough for a Ranella ; transversely striate and a row of 

 tubercles on each whorl ; scorched deep livid brown, the varices banded 

 brown and white ; mouth very white. Long, 72, lat. 43, whorls 6, decollated. 

 Common. S.E.A., S.A. 



Ranella vexillum. Soiuerhy, Conch., Illust. Ranella, fig. 3. A fusiformly 

 ovate shell, depressed, with fine transverse and irregularly noduled ridges ; 

 brownish, regularly banded with reddish brown lines ; outer Hp minutely 

 toothed. Long. 40, lat. 26. whorls 5. Common. Reeve gives another 

 figure and habitat, and, therefore, I doubt if the Tasmanian one is R. vexiUum 

 of Sow. 



Ranella epitrema. Tenison- Woods. 



PiSANiA reticulata. A. Adams, Zool. Proc. 1854, p. 138. An oblong 

 turretted shell, densely reticulated and of imiform purple brown color ; 

 upper whorls granulated ; seldom more than one varix at the Hp. Long. 30, 

 lat. 12, whorls 7. Rather common ; V. Said by Mr. Adams to occur in 

 New Caledonia. 



PiSANiA tasmanica. Tenison- Woods. Smaller than the preceding, and 

 white vidth irregular varices. It seems, however, doubtful to me whether 

 this is more than a variety. 



Cominella tenuiscostata. Tenison- Woods. 



^ Cominella alveolata. Kiener, Spec. Conch., Buccinum, fig. 13 fvar. 

 lineolata). A handsomely striate nodose shell, chequered black and white ; 

 very variable ; specimens from King's Island are banded green and brown, 

 and have an appearance not unlike an Ancillaria. Common. S.A., S.E.A. 

 Long. 30, lat. 15.
