marked with black spiral lines. Height 20 to 70 mil. Common in all 

 Tasmania and extra-tropical Australia. 



Trochocochlea tjeniata. Quoy and Gaim., loc. cit, p. 251, pi 63, 

 Jig. 15. (There is reason, however, for thinking that the figure refers to 

 Lamarck's T. constricta). Small, smoother and much less conspicuous 

 keels, 3 to 6 (at most) in body whorl ; color, long zigzag streaks of white 

 and blue, black, greenish, or even red (especially on dead, old, and dry 

 shells), outer Hp generally margined with black, throat of dark pinkish nacre, 

 seldom lirate, columella brownish, tubercle obsolete. Long. 18, lat. 16 mil. 

 Always smaller than the preceding, and with the same geographical dis- 

 tribution. With this shell I unite T. muUicarinata, Q. and G., and T, 

 ■porcata, Adams, and even then it is only a doubtful species. 



Trochocochlea compta. Tenison- Woods. 



Trochus (diloma) odontis. Wood. Index, Test, Suppl., pi. 6, Jig. 37. 

 Small, depressed, dark blue, with lines of fine yellow spots. Mouth nacre 

 rose color, with green margin. Common, and in all extra-tropical Australia. 

 Diloma is a questionable genus of PhHippi not admitted by Gray. The 

 horny operculum, the animal, and all the habits of this shell would unite it 

 with TrochococJdea ; but the shell itself is smooth ; the interior especially 

 of the upper whorls is a brilliant rosy nacre ; the foot lappets fringed and 

 they are spotted yellow hke the shell.

Stomatella imbricata. Lamarck, Encyd. Meth., 'pi. 450, Jig. 2. 

 Elegantly grooved and striate, and densely imbricate with raised scales ; 

 dull, white, nacreous inside. Maj. diam. 29, min. 23. B Sts., rare, and 

 inS.A. 



Gena STRIGOSA. A. Adams, Zool. Proc, 1850,^. 37. The only species 

 known in Tasmania. Oblique, and variously striped with green, red, etc. ; 

 outer Kp sKghtly sinuate. Long. 21, lat. 11, alt. 5. Bass' Sts., rare, and 

 in S. A. The figure in Reeve, pi. 2, Jig. 12, is very defective. 



Haliotis n^vosa. Martyn, Univer. Conch., v. t. 11, Jig. 63. This 

 common ear-shell of the coasts of Australia and Tasmania has received a 

 host of names. It is even now, I beUeve, unnecessarily divided into two or 

 three species. Some of its varieties extend into the genus Fadollus, as it is 

 frequently found with the mesial spiral rib. H. coccoradiata, Reeve, is 

 another variety. A scabrous irregularly rugose shell, variously whorled, 

 red brown being the prevailing shade, and very nacreous within. 



Haliotis glabra. Swainson, Cat. Bligh Collection ; (H. albicans of 

 Quoy, Angas, etc., but Swainson's name was published in 1830). A very 

 large, soHd, smooth species, generally worn white, but in young shells 

 banded or broadly rayed with chestnut or green ; lines of growth few, deep, 

 and irregular. N. and in S, A. 



Haliotis carinata. Martini, tab. li,Jig. 140. This species or variety 

 for it is uncertain which, was described by Swainson in the Bligh Catalogue, 

 and again by Dr. Gray (teste Angas loc. cit. , who gives the reference. Gray, 

 MS., Brit. Mus.) as H. emmce. Somewhat common, and S.A. 



Haliotis elegans. Koch. inPhilippi. Abbild und Besch, Conch. Haliotis, 

 pi. 4, Jigs. 1 and 2, Teinotis elegans, Gray. Swainson says he found this 

 species in the islands in Bass' Straits. Proc. Roy. Soc, Vol. 3, part 1, 

 p. 49.
