SPONDYLUS. 12] 
which I have obtained from Tournay agree perfectly with the Engish examples, 
but the example figured by d’Archiac appears to differ in having the umbo of the 
left valve less produced. 
S. subcostulatus, Stoliczka,' appears to be a closely allied form, and was indeed 
regarded by Geinitz as identical with S. striatus. 
S. complanatus, @Orbigny, is imperfectly known, but may be closely allied to, 
or identical with, S. striatus ; it is recorded by Morris from the Lower Greensand 
of Folkestone. 
Remarks.—This species is known chiefly from specimens found at Warminster. 
An example from that locality m Mr. J. F. Walker’s collection shows the interior 
of the right valve. The size of the attached surface varies considerably in different 
specimens. 
Specimens showing the interiors of fixed valves, resembling SY. gibbosus and 
S. latus, occur in the Blackdown Greensand and the Gault of Folkestone, but I am 
unable to determine the species without more specimens. 
Type.—From Chute Farm, Warminster, in the British Museum. 
Distribution —Lower Greensand of Faringdon. Rye Hill Sand of Warminster. 
Upper Greensand, Longleat. Cenomanian Sandstone of Wilmington. Base of 
Chalk Marl of Maiden Newton. Cenomanian (Bed 11) of Branscombe.
