278 APPENDIX TO THE SUPPLEMENTS TO 



it has been ascertained that they occur in blocks of stone, in all probability from Normandy, 

 landed near Chideock and from these the fossils had been extracted and placed in the 

 museum of the Bridport Institution, by mistake, as from Chideock. They had been 

 sent to me for inspection by Mr. C. Moore, who firmly believed them local. I all along 

 felt very uncertain about the matter, and am glad to have been able to rectify the mistake.

This rare British shell is described at p. 18 of my ' Oolite Monograph.' Since then 

 a perfect bivalve example was found by the Rev. G. E. Whidborne in the Middle Lias 

 {Cymbium zone) at Chideock. It measured : 

 Length 2g, breadth 3 lines. 



In the ' Compte-Rendu Sommaire des Sciences de la Societe Geologique de France,' 

 10th February, 1880, M. Munier-Chalmas proposes a new genus, Koninckella, for this 

 species, with the following brief diagnosis : — " Test concavo-convexe ; spire branchiale 

 formee par trois ou quatre tours disposes comme dans le genre Koninchina de Suess. 

 Epines cirrhiales ties developpees. Type : Leplana liasiana, Bouchard." Fie adds that 

 of the seven species of Leplana stated to occur in the Lias, four only are referable to the 

 Lcplanida ; the three others, L. liasiana, L. Bouchardii, and L. rostrata, are provided 

 with spiral appendages, and should become the type of a new family, Koninckinida. 

 This I had previously proposed in 1853, but M. Munier-Chalmas was not aware of it 

 when he proposed in 1880 his family Koninckinida. Indeed, I believe that none of the 

 so-termed Leptana that occur in the Jurassic formation are really referable to Dalman's 

 genus. The genus being limited to the Silurian, Devonian, and Carboniferous formations.

This shell, described at p. 19 of the Oolitic Monograph, and at p. 92 of the Jurassic 

 Supplement, as a Leptcena, is now placed in the genus Koninckella, ' Jurassic Supple- 

 ment,' p. 92.

 The species described at p. 92 as a Leplana, is now removed to the new genus.
