llab. West coast of New Holland. 



Unlike the typical species of the Indian Ocean, the an- 

 terior side of the Australian and Japanese species of 

 Meroe is the shorter. 



Species 8. (Mus. Cuming.) 



Meuoe Alici.e. Mer. tfntd corclalo-oi-bicidari, depres- 

 siii-Hcidd, lecviffatd, Jlitvesceiite-albd, pmpureo-roseo re-

Alice's Meroe. Shell cordately orbicular, rather de- 

 pressed, smooth, yellowish-white, reticulately freckled 

 and obscurely rayed with purple-rose. 



Sunetta Alicdre, Adams and Angas, Pro. Zool. Soc. 1863. 



Hab. Port Elliott, South Australia; Angas. 



This species, dredged at Port Elliott, South Australia, 

 by Jlr. Angas, comes very near to the preceding ; it is, 

 however, rounder and more gibbous. 



Species 9. (Mus. Cuming.)

The mensirual Merge. Shell orbicularly ovate, rather 

 gibbous in the middle, anterior side short, whitish, 

 lineaj'ly waved with livid-purple, smooth, obscurely 

 radiately striated beneath the lens.

 Cniieiis i/n'Hs/nifdis, Deshayes. 



Sab. New llulland ■;■ 



This appears to be an important species, intermediate 

 in characti-r between the smooth Australian form, M. va- 

 ffiiia/is, and M. triinc(diis of the Philippine Islands. 



Species 10. (Fig. a, b, Mus. Cuming.)

Sglander's Merge. Shell somewhat triangularly ovate, 

 swollen, nearly equilateral, cream-colour, undulately 

 blotched or lineated with livid-purple, covered with 

 a thin horny epidermis, smooth.

Of a swollen gibbons form, nearly ecpiilateral, but some- 

 what variable.

Merge excavata. Meroe tesld orbicnlari-ovaid, unlice

 The excavated Merge. Shell orbicularly ovate, an- 

 teriorly compres.sed and cordately attenuated, poste- 

 riorly broadly rounded, whitish, more or less stained 

 with fulvous-violet, interruptedly banded with purple, 

 smooth, [)artially covered with a thin horny epi- 

 dermis.

 Aferoe excavata, Sowerby. 

 Ciineus excavatus, Deshayes. 

 Ilab. Japan. 



The painting of this species is similar to that of the 

 large species from the same locality, which I have named 

 M. maynijica. It ditfers in form in having the posterior 

 side liroailly rounded and the anterior compresjly atte- 

 nuated.
