the latter has also found Nummulites (including probably N. 

 Ramondi) in the sea-sand off Gasconj. Indeed our friend M. 

 E. Van den Broeck suggests the question, Can the Gulf-stream 

 have had force enough to drift the fossil Nummulites from the 

 Bay of Gascony to the English Channel ?* 



So many of the aforesaid fossil Foraminifera, dredged up 

 in the Channel, being near their well-known formations in 

 England and France, and one of the Nummulhice {N. Prest- 

 wichiana) occurring in Hampshire, if not also in Belgium, we 

 need not look for a distant origin for them ; and their strata 

 may be, or may lately have been, in place between France 

 and England. Further, though several of the specimens ol 

 -A^. Ramondi and N. Rouaultt are greatly worn, many show no 

 sign of having travelled very far, and those that have been 

 worn down have not suffered more than the Discorhince and 

 others. 



At all events, the facts are suggestive of further research. 



PS. In a letter dated March 7, 1876, Prof. Ansted favours 

 us with his opinion that " it is not impossible or very unlikely 

 that Foraminifera should be drifted from the Bay of Biscay 

 to the Channel Islands. Whatever lives in the southern part 

 of the former sea may be drifted westward by the return 

 storm-waves, reflected from the French coast (and making the 

 notoriously bad and broken seas met with in crossing the Bay) 

 much westward of the line up which comes a drift from the 

 south, caused by the return or back current of the Gulf-stream, 

 when it gets well to the south. Any thing like Foraminifera 

 would then be caught by the tide-wave and carried up- 

 channel." 



XXVI. — Notes on some Heteromerous Coleoptera belonging to 

 the true TenebrionidEe. By Charles O. Waterhouse. 



Having recently had occasion to refer to one of Motschulsky's 

 papers on Tenebrionidaj published since his death in the 'Bul- 

 letin de Moscou ' (1873, p. 2;3), I have thought that a few 

 remarks on it raigiit be useful. At the same time, I must 

 emphatically protest against the publication of this author's 

 papers, which, it is clear from internal evidence, were written 



• M. E. Vanden Broeck remarks that M. A. Lafont, in his paper on 

 the Fauna of the Arcachon liasin, says that Spirula Peronii is sometimes 

 found on the coast, evidently brought by the currents from the south 

 ('Actes Soc. Linn. Bordeaux, ser. 3, vol. vi. 18G8).
