113. — G. dentata, Krauss^ Nova Acta Acad. Leop.-Car.^ vol. xxii, pt. ii^ p. 458^ is from the 

 upper secondary beds on the Zwartkop river of South Africa^, regarded by Krauss as cretaceous^ 

 but subsequently by other geologists as Jurassic.

115-118. — G. ensiformis, Con.^ gregaria, Shum.^ recta and suUoHuosa, M. and Hayd._, are

 as already noticed, transferred by Bosquet to the gQnu^ Melina [^= Pernajj (see Foss. fauna and

 Lethsea Hoss., xmelivr., 1867, p. 499. 



144. — Melina grandiosa is from the South Indian cretaceous rocks. 



145-146. — Inoceramus neocomiensis ^ d^Orb., Jaccardi, P. and Camp. 



147. — I, sulcatus, Park., is the type of the sub-genus Actinoceranius of Meek. 



148-149. — 7. concentricus , Park., and Salomoni^ d^Orb. 



150.— Z. Coquandianus, d'Orb., has entirely the form and smoothness of ^he shell of an 

 Aucella. Pictet and Campiche state that there are two pits below the beaks noticeable on cast 

 specimens, but they do not say whether there is one or two in each valve. It is necessary to 

 ascertain the character of these pits, whether they are really ligamental pits, or whether they are 

 produced by hinge-teeth. In Aucella there is generally a small blunt tooth below the beak of the 

 flatter, right valve, and it fits below the hinge-margin of the left valve in a special groove. Thus 

 on the cast there would be on the left valve two, on the right one impression produced and this 

 would almost appear to be indicated in one of Pictet and Campiche's figures of the present species.

t According to Pictet probably identical with J. undwlatus, Mant., pictns, Sow., concentricus (ex parte) 2^x1^ 

 cordiformis, Goldf., pernoides, Math., tegulatus, Gein., (non Hagenow). Giimbel (Geog. Beschreib. Ostbay. 

 Grenzgeb., 1868, p. 766), proposes for anotber pecuHar form the name I. striato-concentricus. 



% Probably identical with I. propinquus, Miinst. An alUed species under the latter is described by Eichwald 

 from Khoroscbowo (Leth. Boss., x livr., p. 487) ; it may also belong to striatus.
