Otolithus (Scopelus) circularis n. sp. (Plate 61, fig. 2.) 
Dimensions.—2} х 
Description.—Circular ; outer side domed with radiating lines, inner side 
flat; notch in ostium ; lower line of suleus with angle between ostium and 
cauda. 
Осситтепсе. —А. TR example from Target Gully, received from Mr. 
H. J. Findlay (type specimen, coll. H. J. Finlay. 
Observations.— his differs in outline and in shape of sulcus он 
preceding species, also in having radiating furrows on outer side. 
described in 1911 (4, p. 39) a circular otolith with a distinetly сор i 
sulcus as О. (Solea) гани from the Miocene of France, but this had a 
straighter suleus than the species now described, which has an outer side 
unlike any otolith of the Soleidae. 
This is without doubt a new species, which I have named Otolithus 
(Scopelus) circularis 
Age.— Tertiary T R Oamaru series.
