The occurrence of Teretrahula capillata in the " Grey Bed " in two 

 localities is worthy of special notice, as up to the present time this 

 fossil has been considered peculiar to the " Red Chalk," with the excep- 

 tion of two specimens found in the Lower Greensand of Upware t- 



The assemblage of fossils from the " Grey Chalk "of Lincolnshire 

 calls for no special remark, with the exception of an Echinoderm 

 recorded in the East Lincolnshire memoir as Anancliytes ovatus. 

 This Urchin appears to have been named from an examination of 

 much crushed and distorted specimens, and its occurrence is re- 

 marked on as an anomaly (p. 147). I have, however, been fortu- 

 nately successful in obtaining specimens in a more perfect condi- 

 tion, and the form in question proves to be a Holaster. A descrip- 

 tion of it by Mr. Jukes-Browne is appended to this paper. 



To the list of fossils of my own. collecting from the Lower Chalk 

 of Lincolnshire I have added those given in the Survey Memoir on 

 Lincolnshire. On referring to that memoir, it will be seen that 

 Tables VL & YIT. contain the fauna which occurs below the lower 

 pink band. My own experience of collecting was that this fauna 

 did not pass up above the " Grey Bed " about 3 or 4 feet above 

 the coloured chalk. Indeed Mr. Jukes-Browne remarks, on p. 58, 

 " from the grey beds at the base [of the pit] Mr. lihodes obtained 

 many fossils (see Appendix, p. 144)." 



As I recognize in the " Grey Bed " the equivalent of the Totternhoe 

 Stone, the underlying chalk must be the equivalent of the Chalk 

 Marl, to which division only the fossils given in Table YI. of the 

 memoir should be referred.
