Species 32. (Mus. Cuming.) 



Haliotis Sieboldii. Hal. testa subobliqtie ovatd, snb- 

 pediuatd, valde convexd, apice termhiall, vix spirali ; 

 radiatim limtd, liris obtusis, ■mbdi-siantibiis ; forami- 

 nibus suhampUs, guink perviis ; extiis aurantlo-riihrd, 

 Vitus albicante, irridescente. 



Siebold's Haliotis. Shell somewhat obliquely ovate, 

 a little pectinated, veiy convex, apex terminal, scarcely

This very remarkable species, which is at present unique 

 in the collection of Hugh Cuming, Esq., has very much 

 the form of a ConcJiolepas or the left valve of a Cardium ; 

 its resemblance to the latter is, however, probably the more 

 striking. It is of a hoOow ventricose growth, the apex 

 with scarcely any spiral, terminating on the margin, like 

 the umbone of a Cockle. 



Species 33. (Mus. Cuming.) 



Haliotis bistriata. Hal. testa oblongo-ovatd, subpla- 

 nulatd, spiraliter liratd, liris valde irregularibus tiimc 

 latis, nunc auguMis, interstitiis incisis ; latere sinistro 

 latiusculd, foraminibus senis perviis ; rubido-fusco viri- 

 dique variegatd, maculis albidis irregularibus iiiterdum 

 aspersd. 



The double-steiated Haliotis. Shell oblong-ovate. 



rather flattened spirally ridged, ridges very irregidar> 

 sometimes broad, sometimes narrow, interstices en- 

 gi'aved ; left side rather broad, six holes open ; varie- 

 gated with gi-een and reddish brown, sometimes 

 sprinkled with irregular white spots.

This species may be recognised by the very irregular 

 vdAih of the ridges and sharply engraved interstices ; it 

 is sometimes veiy prettily variegated with red and green, 

 but a dark reddish brown sprinkled with whitish spots is 

 the predominating colour. 



Species 34. (Mus. Saul.) 



Haliotis tuberculata. Hal. testa ovatd, comexo-de- 

 pressd, spiraliter inciso-striatd, radiatim tuberculato- 

 plicatd, plicis incequalibm, plus minusve tumidis ; 

 rubido-fuscd, viridi aut rufescente variegatd. 



The tubeeculated Haliotis. Shell ovate, convexly 

 depressed, spirally deeply striated, radiately tubereu- 

 larly plicated, plaits imequal, more or less swollen ; 

 reddish brown, variegated with red and green.

Extremely variable in its colouring, which is sometimes 

 a dull mixture of red and green, at other times a reddish 

 brown ornamented with light green zigzag waves, as in the 

 specimen selected for illustration.
