Species 17. (Mus. Cuming.) 



Haliotis sanguinea. Hal. testa oblongo-ovatd, antice 

 Jlexuoso-coHtractd e.t aiienuata, parte spirali suhelevatd, 

 concentrice ohlique corruyatd et striatd ; foramimbus 

 creberrimis, ad novenis perviis; fused (in atatejuveni

The blood-stained Haliotis. Shell oblong-ovate, 

 anteriorly flexuously coutracted and attenuated, spiral 

 portion of the shell rather elevated, concentricaUy 

 obliquely wrinkled and striated, holes very close 

 together, about nine open ; browTi (varigated with 

 white in a young state), spu'e pecidiarly tinged within 

 with blood red.

 Haliotis fciformis, Menke. 



Hah. Cape of Good Hope. 



This species may be easily recognised by its obliquely 

 wrinkled and dai-k chocolate brown exterior, and by an 

 irridescent blood stain within the winding cavity of the 

 spire ; the holes are very numerous and unusually close 

 together, and the anterior portion of the shell is peculiarly 

 flexuous and attenuated. It was originally described and 

 figured by Mi-. Hanley, in a little work called ' The Young 

 Conehologist's Book of Species '. 



Species 18. (Mus. Cuming.) 



Haliotis asinina. Hal. testd elongato-ovatd, subcttrvatd, 

 postice fiexnoso-acwnitmtd, spird termiiiali, oblique 

 irregulariter striatd, parte posticd liris suMilibus sub- 

 distantibus e apice radiantibm, deinde evanidis ; fora- 

 mimbus parviusculis, numerosis, ad octonis perviis ; 

 olivaceo-viridi, maculis fuscis perpaucis subtrigonis, 

 fiammis lutescentibus, lineisque fuscis numerosis breinbuj 

 interruptis pulcherrime variegatd, radiis viridibu^ et 

 rufo-Jlavis nndatis prope apiceni alternatim pictd. 



The ass's Haliotis. Shell elongately ovate, slightly 

 curved, posteriorly flexuously acuminated, spire ter- 

 minal, obliquely irregularly striated, posterior portion 

 of the shell with fine rather distant ridges radiating 

 from the apex, then fading away ; holes rather small, 

 numerous, about eight open ; olive green, beautifully 



variegated with a few triangular brown spots, yel- 

 lowish flames and numerous short interrupted brown 

 lines, and painted with alternate green and reddish 

 yellow zigzag rays next the apex.

 Cuming. 



This very prettily variegated species, the most elongated 

 of the genus, is remarkable for the extra-terminal convolu- 

 tion of the spii'e. 



Species 19. (Mus. Cuming.) 



Haliotis gigantea. Hal. testd ovaid, spiraliter costatd, 

 costis parvis crebris irregularibus obtusis, interdum 

 subobsoletis, oblique nodoso-undatis ; foraminibus am- 

 plii, pecuUariter tubuhsis, tribus qiiaternisve perviis ; 

 extus spadiceo-rubente, intus albicante pallide viridique 

 irridescente. 



The gigantic Haliotis. Shell ovate, spirally ribbed, 

 ribs small close U'regular obtuse, sometimes some- 

 what obsolete, obliquely nodosely waved ; holes large, 

 peculiarly tubidar, tlu-ee to four open ; exterior fawn 

 red, interior irridescent with white and pale green. 



Chemnitz, Conch. Cab., vol. x. pi. 167. f. 1610, 1611. 

 Haliotis tiibifera, Lamai'ck. 



Hab. Japan ; Dr. Siebold. 



The word gigantea is a much less appropriate term for 

 this species than tiibifera, for there are fom- or five others 

 of larger size, but none in which the orifices are so pecu- 

 liarly tubular ; the rule of priority nevertheless requires 

 that it should be adopted in preference. It was wrong of 

 Chemnitz to introduce this shell imder the name of gigan- 

 tea, when he considered it to be identical with the H. 

 navosa of Martyn ; it happens, however, that these are 

 two distinct species, and both names, therefore, must be 

 maintained. The H. gigantea is a pecidiar light fawn- 

 colom-ed red shell from Japan, well distinguished by the 

 tubidar structure of the holes ; the H. neevosa (for which 

 see Plates VIII. and IX., Fig. 37), is of a deep coral red, 

 sometimes green, variegated, from Van Dieman's Land, 

 and of smaller size.
