1032 PATELLA. 



Patella radiata. Chemnitz, xi. p. 180. 1. 197. f. 19l6 and 

 1917. 



Inhabits the coasts of the Nicobar and Molucca Islands. 

 Chemjiitz. 



This shell appears by the figures to be about eleven lines long, 

 and nine broad at the broader end, and to be marked with 

 decussated striae ; the margin is somewhat angulated and 

 crenulated ; the inside has a pearly coat, through which the 

 external rays appear, and the muscular impression is brown. 



LUGUBRis. 37. Shell sub-oval, depressed, thick, 

 black, with longitudinal ribs and transverse 

 stride ; margin white and crenated.

 Le petit Deuil. Favanne, i. p. 491. t. 1. f. M. 

 Martini, i. p. 112. t. 8. f. 60. 



Inhabits the coasts of Provence and Cyprus. Favanne. 



Shell with the base about two inches long, and four-fifths as 

 broad ; the sides are blackish with the ribs darker, and the 

 summit as well as a band round the marghi are white ; La 

 petit Deuil is described by Favanne with two irregular rows 

 of spots round the summit, and the margin orange ; but I 

 have no doubt of its belonging to the same species. Adan- 

 son's description of Le Libot, agrees much better with this 

 shell than with P. miniata, to which Gmelin has referred it. 



fULGATA. 38. Shell sub-oval, with about fourteen 

 obsolete ribs, and intermediate strise ; margin 

 sub-angulated, dilated and acute.
