Hob. Australia; King. 



An extremely interesting species, weU characterized by 

 its close ribs of scale-like tubercles, ranging across the 

 shell in oblique waves ; in the middle portion of the shell 

 there is a fine ridge ninning between the ribs ; the colour 

 is also pecidiar, a kind of burnt-umber-stained orange. 



Dr. Jonas of Hambirrgh informs me that there is another 

 specimen in the collection of Dr. Eoding of that city. 



Species 31. (Mus. Cuming.) 



Haliotis elegans. Hal. tesld elongato-ovatd, subjlexuosd,

The elegant Haliotis. Shell elongately ovate, rather 

 flexuous, convex, apex terminal ; spu-ally ribbed, ribs 

 thin, narrow, elevated, lamcUa-like, somewhat obso- 

 letely closely scaled along the simunit, interstices 

 between the ribs rather deeply grooved and striated, 

 holes small, distant, about eight open ; orange cream 

 coloiu:, streaked and variegated with orange red, in- 

 terior wliitish, pearly.

Hab. Port Adelaide, New Holland. 



This is a truly elegant species and very distinct from 

 any hitherto known ; its form is that of a gracefully 

 curved elongated oval, covered with erect close-set lamella- 

 like ribs, spii-aUy radiating from the apex, the summits of 

 which are swollen and bent over with scales fitting closely 

 one upon the other. Its general tinge is that of an orange 

 cream colom'. 



Species 22. (Mus. Cuming.) 



Haliotis coccinea. Hal. testa oblongo-ovatd, spiraliter 

 Uratd, liris creberrimis inaqualib/is, interstitiis trans-

 quinis senisve perviis ; extus coccineo-rufd, lutescente- 

 albo maculatd et variegatd, intus argenteo-albicante. 



The scarlet-clad Haliotis. Shell oblong-ovate, spi- 

 rally ridged, ridges very close, unequal, interstices 

 transversely finely striated ; holes rather close, five 

 or six open ; exterior scarlet-red, spotted and varie- 

 gated with yellowish wliite, interior silvery white.

The ridges have a tendency to range alternately singly 

 and in pairs, but are very m-egidar. 



Species 33. (Mus. Cuming.) 



Haliotis Cracherodii. Hal. testa ovatd, convexd, spird 

 suboccultd; IcBvigatd aut radiatim striata, foraminibus 

 parvis, senis ad octonis perviis, extus cmruleo-nigricante, 

 intus albicante, margaritaced. 



Ceacherode's Haliotis. Shell ovate, convex, spii'e 

 somewhat concealed; smooth or radiately striated, 

 holes small, about six to eight open ; exterior blueish 

 black, interior whitish, peai-ly.

Hall. Cahforuia. 



It may perhaps be as well to mention that the fine 

 specimen of H. Cracherodii here figured fi'om Mr. Cuming's 

 collection, is of unusually large size ; it is of a pecidiar 

 bottle-blue black colour externally, and has never more 

 than eight of the perforations open.
