REPORT — 1897. 



to securis, and Mr. Meyer, to whom a specimen was sent, is of the same 

 opinion. The two species are so closely allied that some palseontologists 

 regard them as identical ; but there are slight differences, and Messrs. 

 Sharman and Newton agree with me in considering the Moreseat speci- 

 mens to be smaller and shallower in the valve than the ordinary A. cari- 

 nata of the Upper Greensand ; and in these respects they resemble 

 A. securis. In some of them, moreover, the ribs on the posterior area are 

 like those in d'Orbigny's hgure of securis ; so that, if the forms are sepa- 

 rable, I think these should be listed as securis. 



Leda scapha (?), d'Orb.— I have seen two casts which probably belong 

 to this species, though they equally resemble L. Marice of the Gault, for, 

 as Mr. Gardner has remarked, there is very little difference between these 

 species. 



Pectunculus umbonatus, Sow. — This is another of Mr. Salter's identi- 

 fications, and unfortunately it also is only an internal cast. There are 

 several species of Pectunculus to which such a cast might belong, but the 

 probabilities are against its being P. umbonatus. As no other specimen 

 has occurred among the fossils recently collected, it will be best to leave 

 it without a specific name for the present. 



Turbo, like Goupilianus, d'Orb. — There is one specimen, a portion of 

 the external impression of the shell, showing an ornamentation resembling 

 that of Turbo G'oupiliamis, which is a Cenomanian species. This speci- 

 men, however, was sent to Mr. Meyer, who informs me that he has an 

 imperfect specimen from the Vectian of the Isle of Wight which it equally 

 resembles. 



Ammonites jlexisulcatus (?), d'Orb. — A small Ammonite was found in 

 breaking up a lump of the material sent to me, and was forwarded, with 

 other specimens, to Messrs. Sharman and Newton. They reported that it 

 most resembles A. Jlexisulcatus, though the portion preserved is smootli 

 and without sulcations. 



Nautilus sp.. Sow. — Among the fossils sent me by Mr. Milne is the 

 cast of a Nautilus, badly preserved, but showing strong transverse rugations 

 or ribs like those of N. radiatus, but its condition is such as to prevent 

 any certainty of identification. Mr. A. H. Fooi'd has kindly examined the 

 specimen, but could not venture to name it.
