SUPPLEMENT TO THE BRITISH 



Position and Locality. Specimens from two to sixteen lines in length are very 

 abundant in the Neocomian or Lower Greensand (phosphate beds) of Upware, and some 

 single valves were found by Mr. Meyer in the Bargate Stone of Guildford. 



20. Trigonosemus elegans, Koenig. Dav., Cret. Mon., PL IV, figs. 1 — 4. 

 Nothing to add. 



21. Trigonosemus incertus, Lav. Dav., Cret. Mon., PI. IV, fig. 5. 



Specimens have been found by Mr. Meyer in the Chalk with green grains (Chloritic 

 Marl) at Cliff, west of Beer Head. 



22. Terebrirostra lyra, Sow. Dav., Cret. Mon., PI. Ill, figs. 17 to 28. 



The perfect loop has not yet been discovered, but sufficient has been found to show 

 that it extended to near the front, and that there existed a short septum in the dorsal 

 valve. 



Dr. S. P. Woodward (' Manual,' p. 21 7) adopted the generic and specific name 

 "Lyra {Meadi), Cumberland, ' Min Con./ 1816," thus placing the designation 

 Terebrirostra Lyra among its synonyms ; but as Cumberland's name was only a 

 manuscript one, and Sowerby subsequently both described and illustrated the shell 

 under the specific name of lyra, this last, I think, should be retained for the species, 

 and has been so adopted by almost every Palaeontologist. 



23. Kingena lima, Def., sp. Dav., Cret. Mon., PI. IV, figs. 15 to 28, and PI. V, 



figs. 1 — 4. 



Dr. Schloenbach regards as synonyms of this species T. pectoralis, Roemer, 

 Kreid., &c. ; T. disparialis, Geinitz (not D'Orb.) ; T. Wacoensis, Roemer ; T. formosa, 

 Kner ; T. sexradiata, E. Deslong., and Mayos pumilus, Heirn. I am not, however, 

 sufficiently acquainted with some of these to be able to confirm his statements ; and I am 

 of opinion that Dr. Schloenbach has figured more than one distinct species under 

 Defrance's K. lima. Kingena lima seems to have enjoyed a very extended vertical and 

 horizontal range ; for, in addition to the localities already given, it has been found by 

 Mr. Judd in Chloritic Chalk at Hanna's Farm, Belfast, Ireland. The Rev. S. Lucas
