JURASSIC AND TRIASSIC BRACHIOPODA. 179

This fossil is stated by Mr. E. Deslongchamps to be a well-marked variety of 

 W. resupinata, and is found in the same bed and localities. It seems to me, however, 

 to differ more from W. resupinata than does this last from W. florella. Dr. Oppel 

 mentions the localities of Pliensbach, near Boll, and Hinterweiller, near Tubingen (' Die 

 Jura-Formation/ p. 184).

Dr. Oppel, in his ' Die Jura-Formation,' p. 184, refers this species (?) to W. Heyseana 

 of Dunker, but I do not yet see any reason for that conclusion. Dr. D. Brauns 

 informs me by letter that much confusion exists respecting it, as Quenstedt mingled the 

 true W. Heyseana with young specimens of W. Waterhousi, but he corrected his mistake 

 subsequently in the ' Die Brachiopoden/ where he gives accurate figures of the beak, 

 deltidium, and foramen of the true W. Heyseana. According to Dr. Oppel and Mr. J. F. 

 Walker, who have visited the locality of Bugbrook, near Weedon, in Northamptonshire, 

 the specimen in the British Museum was not, as the label indicates, derived from the 

 Inferior Oolite, as was supposed to be the case, but from the Middle Lias, that formation 

 occurring in the locality. The Lincolnshire Limestone and the red Northamptonshire 

 iron-sands represent the Inferior Oolite in this district. Mr. E. Deslongchamps is, 

 moreover, now of opinion that the shell he described in his ' Brachiopodes Jurassiques ' 

 under the name T. Heyseana belongs to another species.

Mr. E. Deslongchamps observes that, although W. carinata is a well-characterised 

 species, it might be confounded with several Liassic and Oolitic shells. I might add that 

 it even resembles some Neocomian forms. The shape, however, of the exceedingly small 

 foramen in W. resupinata, the Liassic species, as compared with the larger and oval foramen 

 of the Oolitic species, would alone suffice to distinguish the two, even if we left out of 

 account the other remarkable characters belonging to W. resupinata, such as its very
