11,3. _(?. denlata, 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. 



114._G^. ala, Coquand, (Province Const., p. 217,) is from Algiers. 



115-118. — G. ensiformk, Con., gregaria, Shum., recla and .snllortuosa, M. and Hayd., are 

 recorded by Meek from North America, (Smiths. Misc. Coll., No. 177, 1864, p. 9).

 as already noticed, transferred by Bosquet to the ^cnns 3Ielina [^^FernaJ, (eee Foss. fauna and

142-143. — Mel. g'lhha, Eichw., and Fischeri, Rouill., are from Neocomien beds of Russia, 

 Lethaea Ross., xmelivr., 1867, p. 499. 



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



145-146. — Inoceramus neocomien-sis, d'Orb., Jaccardi, P. and Camp. 



147. — /. sulcalus, Park., is the type of the sub-genus Aciinoceramus of Meek. 



148-149. — /. concentncun, Park., and Salomoni, d'Orb. 



150. — 7. Coqnandianus, 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 AuceJla 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 east 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 I. nndithitiis, Nant, pirtiis, Sovr., coiicentrictis (ex parte) aixd 

 rordiformis, Goldf., penwide.i, Math., tcgulatttn, Gein., (non Hagenow). Giimbel (Geog. Beschreib. Ostbay. 

 Grenzfeb., ISGS, p. 7C0), proposes for another pecnliar form the name I. stnato-ronccuti-icus. 



X Probably identical with /.^ropi»yMaj, Miinst. An allied species under the latter is described by Eiehwald 

 from Khoroschowo (Leth. Ross., x livr., p. 487) ; it may also belong to sti-iatus.
