case, and it is therefore proposed to assign it a provisional specific name ; and from 
the peculiar character of the dental plate the name Myliohatis curvipalatus will he 
appropriate. 
The contour of the dental plate of M. curvipalatus shows an approach to the 
remarkable one in the same element of Bhynchohatus^ ; and if the resemblance be a 
true one it indicates that the type specimen of the former belongs to the upper jaw. 
Subclass II. TELEOSTEI. 
Order I. ACANTHOPTERYGII. 
Family I. SPA EID^. 
Characters. — Either cutting-teeth in the front of the jaws, or molariform teeth 
on the sides ; palate either toothed or edentulous. 
Genus. CAPITODUS, Munster. ^ 
Characters. — Both palatal and premaxillary teeth present : the latter wider than 
in Sargus. 
Distribution. — Five species were described by MiinsteF from the miocene of the 
Vienna basin; one of these (0. truncatus) having been subsequently recorded by 
RoemeP from contemporary strata in upper Silesia. 
Capitodus indicus, nobis.^ 
(From the eocene of the Punjab. J 
History. — The type specimen has been described by the writer in the notice cited. 
Tooth. — The tooth represented in plate XXXV. figs. 11, 11a was collected by 
Mr. A. B. Wynne from the nummulitics of Kohdt, Punjab ; it is one of the incisiform 
series, and agrees so closely with the teeth of the European species of Capitodus that 
it may be pretty safely referred to that genus. The crown is broad and laterally 
expanded, its dentine having been worn into a deep hollow on the inner surface 
(fig. 11a). The outer surface is coated with enamel, and is convex laterally; its 
width is 0-7, and its height 0'4 inch. 
Affinities. — In its general contour and mode of wear the Indian tooth closely 
resembles the teeth of C. truncatus j but the crown is relatively much wider. In the 
other four European species the crowns of the incisive teeth are still narrower. 
The beds from which G. indicus was obtained are probably of upper eocene age. 
Family II. OPHIOCFPRALIDM. 
Characters. — Head depressed, covered with shield-like scales superiorly ; cleft of 
the mouth lateral, wide ; teeth in the jaw and on the palate. Eye lateral ; a cavity 
accessory to the gill-cavity for containing water. 
Distribution. — The family comprises only the genera Ophiocephalus and Channa 
(the latter having but one species), and is mainly characteristic of the Oriental region,
