APPENDIX TO THE SUPPLEMENTS. 



It will now be desirable to notice a few Cretaceous, Jurassic, Carboniferous, and 

 Devonian Brachiopoda that have been discovered subsequent to the publication of the 

 Supplements relating to the species from those formations. 



CRETACEOUS. 



1. Terebratula ovoides, Sow. Dav., Drift Sup., Vol. IV, PI. I, figs. 12, 13. 



In Vol. IV, p. 10, of my Drift Supplement, I referred to this species as having been 

 found by Sowerby "in a sandstone containing green sand," since then, at p. 154 of 

 4ns valuable Essay on the Neocomian Fossils of England, 1 Mr. W. Keeping says, 

 while describing T. ovoides, that it is " a species to which much doubt and considerable 

 interest attaches on account of its wide distribution in boulders, while it is unknown in 

 situ. It is a large species, with a very characteristic mesial ridge along the large valve, and 

 with the dorsal valve frequently flattened in the specimens from Upware, South Willing- 

 ham, and Herrimere I have found it in a hard green-grey sandstone 



boulder at South Willingham, in Lincolnshire, also at West Dereham, near Downham 

 Market. But its most interesting occurrence is at Herrimere, north of Upware, on the 

 Cam, for here it occurs associated with other fossils whose age can be determined, 

 namely, Lower Cretaceous. I have already given my reasons for believing that this 

 occurrence at Herrimere is not in sitii as has been stated elsewhere (' Geol. Mag.,' 1870), 

 nor of Jurassic age, but that it is really in a boulder of Neocomian Sandstone." 



2. Terebrirostra lyra, Sow., sp. Dav., Cret. Mon., PI. Ill, figs. 17 — 28. 



Appendix to Sups., Vol. V, PI. XVIII, 

 figs. 1, la, 2. 



Since describing this fine species at p. 32 of my ' Cretaceous Monograph ' the 

 British Museum has acquired Mr. Cunnington's fine collection of Horningsham Upper 



1 The Fossils and palseontological affinities of the Neocomian deposits of Upware and Brickhill, Cam- 

 bridge, 1883 (Sedgwick Prize Essay for 1879).
