Hab. New Holland. 



A very striking, brightly coloured species, allied in 

 structure to the H. rubicundus, and belonging to the genus 

 PadoUus of De Moutford.

Haliotis albicans. Hal. testa suborbiculari-ovatd, con- 

 vexd, lavigatd aut spiraliter obsolete liratd; foramini- 

 bus parvis, numerosis, decenis perviis ; extus luteo-coc- 

 ciiied, flaimudis albidis radiatd intus argented.

 Hab. New Zealand. 



No one can fail to distinguish this species by its delicate 

 rayed style of colouring ; the perforations are more than 

 usually small, and the sHveiy interior is characterized by a 

 kind of minute wavy pattern. 



Species 31. (Mus. Cimiing.) 



Haliotis discus. Hal. testa oblongo-ovatd, elevato-con- 

 vexd, hie illic tumidd et rngosd, latere sinistra lato, 

 pecidiariter erecto ; foraminiius amplis, subdistaidibus, 

 tnbiferis, quaternis tantum perviis ; castatieo-fuscd, 

 viridi aut rvfescente radiatim tinctd. 



The auoiT Haliotis. Shell oblong ovate, elevately con- 

 vex, here and there swollen and wiinked, left side 

 broad, peculiarly erect; perforations large, rather 

 distant, tubiferous, fom- only open ; chesnut brown, 

 faintly radiated with red or green. 



Eeeve, Pro. Zool. Soc, 1846. 



Hab. Japan ; Dr. Siebold. 



Chiefly distinguished from any species hitherto recorded 

 by its oblong form, and erect growth of the perforated 

 side of the shell.
