Eeeve, Pro. Zool. Soc, 1846. 



Hub. ? 



Very closely aUied to the H. varla, from which it differs 

 only in the depression of the spire, and a slight though 

 characteristic variation in the scidpture. 



Species 41. (Mus. Cuming.) 



Haliotis astricta. Hal. testa ovatd, conve.rd, spiraliter 

 Uratd, lirls laminis striisque elevatis irreytdaribm ra- 

 diatim decussaiis ; foraminibus quatei'nis perviis ; eirtiis 

 albido olipaceo-ciridiqiie marmoratd, iutus irridescente. 



The tied Haliotis. SheU ovate, convex, spu-ally ridged, 

 radiately crossed with irregidar raised striae and 

 lamiucE ; four perforation open ; exterior marbled 

 with white and olive green, interior nridescent. 



Reeve, Pro. Zool. Soc, 1846. 



Hab. •? 



Distinguished by the strong decussating sculpture of 

 the cross ridges. 



Species 42. (Mus. Hanley.) 



Haliotis gibba. Hal. testa oblongo-ovatd, peculiarlter 

 convexd aut gibbd, spiraliter Uratd, liris irregidaribus, 

 crebriuscidis ; spird subterminali ; foraminibus quit/is 

 perviis ; extus fusco- et caruleo-viridi, strigis albidis, 

 rufo-punctatis, undatis, hderdum oriiatd, intus pecu- 

 liariter irridescente. 



The gibbous Haliotis. Shell oblong-ovate, peculiarly 

 convex or gibbous, spirally ridged, ridges irregidar, 

 rather close-set, spire nearly terminal ; five perfora- 

 tions open; exterior brownish or blueish green. 



sometimes ornamented with white, red-dotted, waved 



streaks, interior peculiarly ii-ridescent.

 Hah. ? 



The inner surface of this very characteristic species is 

 disposed in minute wrinkles, from which the refraction of 

 light throws off a peculiar degree of in'idescence. 



Species 43. (Mus Taylor). 



Haliotis taylobiana. Hal. lestd oblongo-ovatd, soli- 

 diusculd, coHvexd, spird subteriiiiuali ; spiraliter obtuse 

 et irregulariter Uratd ; foraminibus septenis ad novenis 

 perviis; extus coccineo-fuscd, favMo, coccineo-fmco, 

 mnculato, prope spirani nebulatd, intus albicante. 



Tayloe,s haliotis. SheU oblong-ovate, rather solid, 

 convex, spire nearly terminal ; spii'ally obtusely and 

 irregularly ridged ; seven to nine perforations open ; 

 exterior scarlet-brown, clouded near the spire with 

 yellow spotted with scarlet-brown, interior white. 



Reeve, Pro. Zool. Soc, 1846. 



Hab. ? 



I have the pleasm'C of describing this comparatively rare 

 species from specimens in the collection of Thos. Lombe 

 Taylor, Esq. It is of a dull scarlet-brown, the posterior 

 portion of the shell being clouded with pale yellow, pecu- 

 liarly mottled with dashes of the darker colour. 



Species 44. (Mus. Cuming.) 



Haliotis marmorata. Hal. testd depresso-ovatd, dex- 

 trorsum posticl effasd, spird subterminali ; spiraliter 

 plauicoslatd, snlcis intermediis subexcavatis ; forami- 

 nibus senis vel septenis perviis, extus viridi, rufo Marmo- 

 ratd, intus albicante. 



The marbled haliotis. Shell depressly ovate, effused 

 posteriorly on the right side, spire nearly terminal, 

 spirally flatly ribbed, intermediate ridges rather exca- 

 vated ; six or seven perforations open ; dark green, 

 marbled with red, interior whitish. 



Gray, MSS. (private cabinet). 



There is a peculiarity in the growth of this shell, in the 



right posterior extremity lieing so promineutly effused 



round the spii'e.
