Bibliography. 



The earliest allusion to fossil lamellibranch shells from Silurian or Ordovician rocks 

 appears to be Wahlenberg, Act. Soc. Upsal., 1821 ; Dalman, Act. Holm., 1827, 

 p. 372, and Hisinger, 1826, Petrefact. Suec, p. 63, both referred to by Sowerby as 

 figuring the shell now known as Goniopliora cymbseformis under the name Cardites 

 carpomorphus. 



1839. Sowerby, in Pt. II. of Murchison's Silurian System, describes Cypricardia 1 amygdalina, G.t 

 impressa, G. Inndata, C. ? retusa, G. cymbxformis, Pullastra complanata, Cucullxa antiqua, Nucula 1 

 ovalis, Avicula retroflexa? and A. lineata from the Upper Ludlow rocks; Mya rotundata, Cardium 

 striatum, Avicula reticidata ? from the Aymestry limestone ; Cypricardia solenoides, Psammobia 

 rigida, Gardiola fibrosa, G. interrupta, Modiola semisulcata from the Lower Ludlow rocks. From 

 the Caradoe limestone and Llandeilo flags, Area Eastnori, Nucula laevis, Avicula orbicularis, 

 A. obliqua.

1851. Murchison, "Silurian Rocks of Scotland," Q.J.G.S., vol. vii., with description of Pleurorhynchus 

 dipterus, Salter, var. rhomboidem ; but no reference is given to any previous publication, so 

 probably the specific description is by Salter ; but if so the necessity for a varietal name is not 

 apparent. 



1853. Ribeiro and Sharpe, "On the Carboniferous and Silurian Formations of the Neighbourhood of 

 Busaco in Portugal," Q.J.G.S., vol. ix. p. 135. The following lamellibranchs are listed from 

 Silurian localities : — Redonia Deshayesiana, Rouault ; R. Duvalina, Rouault ; Nucula costse, N. Cix, 

 N. rebiero, N. Ezquerrse, N. Eschwegii, N. maestri, N. Beirensio, N. Bussacensis, Leda Escosurx, 

 Dolabra Lusita7iica } Cypricardia ? Beirensis, Modiolopsis elegantulus. The descriptions are by 

 Sharpe.
