BUT while it is difficult to collect fossils in situ in the upper part 

 of the Lower Lias, a very good knowledge of the fauna is 

 obtained from the material which may be collected on the tunnel 

 heaps between Old Dalby and Saxelby. I have been permitted to 

 study the large collection of specimens from these heaps which are 

 preserved at University College, Nottingham, and the Engineer of 

 the Midland Railway Company gave me leave to make small 

 excavations. The following lists give some idea of the fauna, which 

 contains abundant Ammonites, especially of the genera Tragophyllo- 

 ceras, Polymorphites, and Flatypleuroceras . The Foraminifera like- 

 wise are unusually interesting ; a list of genera identified by Wilson 

 has already been given by Quilter'; according to the list given by 

 H. B. Woodward - no Texhdaria-YikQ form is known from the Lias 

 of any other British locality.
