l6o SOME NEW SECTIONS AT ILFORD. 



things, teeth of Bos pvimigenius (Boj.), Rhinoceros megarhinus 

 (Christol), and Microtns grcgalis ? (Pallas). With reference to 

 the last mentioned he writes, " A second upper molar of a small 

 Vole corresponds very closely with that of MicroUis gvegalis in 

 respect to the pattern of its prisms and also in size. It is just 

 possible, however, that this specimen belongs to Microtns 

 ratticcps and since it is somewhat damaged, lacking a prism, it is 

 certainly more desirable to make a provisional, rather than an 

 absolute, reference to Microtus gvegalis. Whether it belongs to 

 one or the other it is an important addition to our list of small 

 vertebrates from Ilford. The Voles from the Pleistocene 

 deposits of Ilford are now represented by five specimens indicat- 

 ing three species, viz., Micvotus amphihius from the Uphall pits 

 (Cotton Coll.) and the Cauliflower Brickyard (a right upper molar 

 in my collection). Micvotus avvalis or agvestis, from the Cauliflower 

 brickyard, in my collection. Microtns gregalis ? from Uphall." 

 We also obtained a few worked flints. 



A small rounded boulder of greywether sandstone was 

 exhumed from the gravel. 



Besides these two fossiliferous sections there are several 

 on the east of Ilford Lane, which have not yet yielded any 

 organic remains, but which are of special interest as they show 

 in addition the " trail." We measured the best of these which 

 was as follows : — 



Surface soil .. ... 2ft. 



(i) Contorted Drift (Trail) ... 4 — ^h 



(2) Sand ... .. nothing to 3 



(3) Gravel ... ... i — g 



(4) Sand ... ... ... I 



(5) Gravel ... ... 4 



(6) Sand and gravel ... ... 4^ feet shown. 



A few lenticular patches of manganese dioxide are .exposed 



in this section. 



December, 1899. 



P.S. — Since writing the above we have obtained another 

 addition to the fossil invertebrate fauna of Ilford, viz., Planorbis 

 nautilcns (Linn.) We are also able to confirm the occurrence of 

 Sucinea oblonga (Drap.), a mollusc which, being confined to a 

 more northern tract, is no longer livin" in Essex.
