REPOUT ON THE BEACHIOPODA. O 



order to obtain some approximate data as to the depths Brachiopoda are at present 

 known to inhabit, it will be desirable to append a list of all the known recent species, 

 with an indication of all their respective depths. 



In 1852 I published in the Annals and Magazine of Natural History a sketch of 

 a classification of recent Brachiopoda based uj)on internal organisation, giving a list of all 

 the recent species then known. Similar and revised lists were subsequently published 

 in 1859 by Professor E. Suess, in 1861 by Lovell Reeve and myself, and in 1870 and 

 1873 by Mr W. H. Dall. In the revised list here appended the range of depth of the 

 European and North Atlantic species has been given me by Dr J. Gwyn Jeffreys, F.R.S., 

 to whom science is so much indebted for his great exertions in promoting those important 

 private and public dredging expeditions from which so many valuable results have been 

 obtained, and for the numerous able reports he has published relating to the same. The 

 approximate ranges in depth at which the larger number of Brachiopoda have been found 

 are in our possession, but of the following no information is given by the original authors, 

 and later researches have not revealed it. It is to be hoped that future dredging expedi- 

 tions will supply the deficiencies. 



Terebratida (?) malvince, D'Orb. I have never seen. 



Terebratulina radiata, Eeeve. A common Korean species. 



Terebratulina (?) patagonica, Gould. 



Wcddheimia raplicelis, Dall. Said to be from Japan. 



Terebratella boucJiardi, Dav. Probably a synonym of another species. 



Terehratella ruMginosa, Dall. 



Terebratella (?) algoensis, Sow. A doubtful species. 



Terebratella (?) labradorensis, Sow. A doubtful species. 



Terebratella (?) lamanoni, Schrenk. A doubtful species. 



Magasella crenulata, Sow. 



Magctsella Icevis, Dall. 



Magasella suffusa, Eeeve. A doubtful species. 



Xraussina nd)ra, Pallas. 



Kraussina cognata, Chemnitz. A doubtful species. 



Kraitssina atkinsoni, T. "Woods. 



Kraussina capensis, Adams and Eeeve. 



Bouehardia (T) fibula, Eeeve. One specimen known, perhaps a large M. cumivgi. 



Rynchonella gra.yi, Woodward. One specimen known. 



Discina antillarum, D'Orb. Probably a synonym of D. striata. 



Zingtda exusta, Reeve. 



Lingida Mans, Swain son. 



l/ingula hiinmdo, Eeeve. 



Livgida reevii, Dav. = L. ovalis. Reeve. 



Lingula adamsi, Dall. 



Glottidia audebardi, Brod. 



It is more than probable that a certain number of the so-termed species recorded in 

 our general list, with respect to which our information is insufficient and unsatisfactory, 

 will hereafter require to be expunged, or placed among the synonyms of some of those
