1866.] WHITAKER — LOWER LONDON TERTIAEIES. 417 



RemarTcs on Mr, G. B. Sowerby^s List of the Fossils. 



The names are in the order of the original list. 



1. Pyrgoma Anglica, Sow. I cannot say what this came from. 



2. Balanus Ohisletianus (new sp.). I did not see this. 



3. Mactra, " a fragment." I did not see this. 



4. Corhula Begulhiensis, Mor. From Oldhaven sand. 



5. RencJclinsiana, Nyst. From Oldhaven sand. 



6. Nucula tenuis, Mont. From Oldhaven sand. 



7. nucleus, Linn. From Oldhaven sand. 



ISTos. 6 and 7 may be the same ; they are much like the com- 

 mon N. labellata of the Lower Eocene. 



8. Pectuneulus Plumsteadianus, Sow. From Oldhaven sand. Should 



be P. Plumsteacliensis. 



9. lAmopsis aurita, Wood. From Oldhaven sand. Mr. S. Y. 



Wood has written to me to the effect that, judging from the 

 figure in Mr. Sowerby's plate, this is not the L. aurita of the 

 Crag. It looks to me like a small obhque Pectuneulus. 



10. Xieana? "fragmentary." From Oldhaven sand. AmereroUed 



fragment of a bivalve shell, but, I think, not a Lucina. 



11. Cyprina Morrtsii, Sow. From Oldhaven sand. 



12. Astarte elevata (new sp.). From Oldhaven sand. 



13. gracilis, Goldf., var. multilineata, Wood. I cannot say 



what this came from. 



14. Burtinii, Lajonk. This seems to have come from Old- 

 haven s;ind, and to be much the same as the foregoing. 



15. Cyrena consobrina, Caill. A bad specimen of a small bivalve, 



most likely an Astarte, from Oldhaven sand. 



16. Cardium Laytoni, Mor. From Oldhaven sand. 



17. Bostellaria Sowerbyi, Mant. From Oldhaven sand (Aporrhais). 



18. Trophon subnodosum, Mor. From Oldhaven sand. 

 ] 9. Pleurotoma, " imperfect." From Oldhaven sand. 



20. Pyrula nodulifera (new sp.). I did not see this from Grove 



Ferry ; but there are some good specimens from the Oldhaven 

 ' sand of the cliffs west of the Reculvers in another draw of 

 Mr. Brown's collection. 



21. Purpura tetragona. Sow. Not from Oldhaven sand; but must 



have got into the collection by mischance. 



22. Clavatula brachyostoma, Wood? From Oldhaven sand (in a 



piece of Cyprina). 



23. Buccinum concinnum (new sp.). From Oldhaven sand. Looks 



much like a London Clay Fusus (unnamed ?) . 



24. CJiemnitzia elegantissima, Mont. There is in the collection a 



shell labelled CJiemnitzia which may have come from Oldhaven 

 sand ; but being small and without matrix, it is hard to say. 

 The same remark applies to ISTo. 25. 



25. Odostomia, " like 0. plicata, Mont." 



26. JN'assa reticosa. Sow., var. costata. Wood. Not from Oldhaven 



sand. Marked as Buccinum costatum in the collection, into 

 which it must have got by mischance.
