Figures. 



Haliotis tuberctjlata. PI. I. Fig. 4. Animal, showing its encircling 

 cirrhated lobe and tentacles. 



Haliotis EmmyE. PL 23. Fig. 131. Shell, of a species from Australia, 

 named by Dr. Gray after his accomplished lady, showing the irides- 

 cent pearly lining of the interior. 



Genus 2. STOMATELLA, Lamarck. 



Animal ; head broad, proboscidiform ; tentacles subulate, with a 



fimbriated lobe at their inner bases ; eyes on peduncles at the 



outer bases of the tentacles ; mantle with the front edge entire ; 



muscle of attachment crescentic, open in front ; foot, with a 



fringed lateral membrane. (Adams.) 



Shell ; more or less ear-shaped, imperforate, externally smooth or 

 sculptured, and mostly bright-coloured, internally pearly ; aper- 

 ture very large, wide open. 



A brilliantly-coloured group of small species, partaking of the character 

 of Trochus and Haliotis, but considerably removed from the typical form 

 of either genus. The animal resembles that of Trochus in having a fim- 

 briated lobe or veil in front, while the shell is that of Haliotis without the 

 holes, the mantle of the animal not being slit in front. Some of the 

 species are operculated and some not. Those without an operculum con- 

 stitute Dr. Gray's genus Gena. The species separated by Lamarck under 

 the name Stomatia present no apparent difference beyond a wrinkling of
