pp. 99. Probably belongs to the next species. Upper Lias, 

 Ilminster. 



26. DisciNA L^vis, Sow. {Patella), Min. Con., t. 139, f. 5, non. 

 14. Melcion suhlcevis, D'Orbigny, Prodr. Patella Icevior, Fleming 

 Brit. Animals. Upper Lias, Whitby (Leckenby). 



27. DisciNA PAPYRACEA, Munster {Patella), Goldf. Petref. t.l67, f. 8. 

 Oppel considers this species to be included under D. reflexa, Sow., 



and quotes it from the Alum Shale of Whitby. 



28. LiNGULA Davidsoni, Oppel. Die Juraf., p. 109. 



This species, discovered by Dr. Oppel in the Oxynotus-shales in 

 Gloucestershire, has a small, narrow shell, apparently smooth, with 

 radial striee, 



29. LiNGULA Metensis, Terquem. Bull, Soc. Geol. de Fr. vol. 

 viii. (1850), t. 1, f. 10. 



This species is most nearly related to L. tenuis of the London clay, 

 but has been referred to L. Beanii by Portlock and others. 



JxL France L. Metensis is confined to the Lower portion of the 

 Lower Lias ; in Ireland it occurs in the zones of Am. angulatus and 

 Bel. acutus ; in England in that of A. raricostatus, Churchdown, 

 (Smithe). 



30. LiNGULA VoLTZii, Tcrqucm, op. cit, t. 1, f. 2. 



This species has been confounded with L. Beanii, from which it 

 differs in its subovate outline, whilst that of the latter is ovate ob- 

 long. According to Dr. Oppel, L. Beanii, as well as Discina reflexa, 

 are fossils of the Inferior Oolite and not of the Lias ; and possibly 

 many of the localities given for that species belong to L. Voltzii. 

 I refer the Lingula of the zone of A. capricornus at Mickleton, and 

 from the Middle Lias of Bath and Chipping Campden, to this species. 



31. LiNGULA LoNGoviCENSis, Tcrqucm. Bull, Soc. Geol. de Fr., 

 1850, p. 12. 



Oppel finds this species in the Alum Shale of Yorkshire ; but in 

 referring Patella Icevis to it, makes a mistake, as that shell is a true 

 Discina. Mr. Leckenby writes — " I think you need take no trouble 

 about Patella Icevis (see Young and Bird's remarks). I send the 

 shell (an Orbicula) for inspection ; you will see it is the same as the 

 little miserable thing Fig. 4, t. 139 (Sowerby)." 



VI. — Alphabetical Catalogue of the Type Specimens of Fossil 

 Fishes in the collection of the Earl of Enniskillen, at 

 . Florence Court. 



Having seen in the September Number of the Geological Maga- 

 zine (p. 408), the Catalogue of Types of Fossil Fishes in the col- 

 lection of my valued friend and fellow-worker Sir Philip de Malpas 

 Grey Egerton, Bart,, M.P., with whom I have collected for so long 

 a time, it occurred to me that the addition of the list of the type 

 specimens of genera and species in my own collection would be 

 a useful supplement to Sir Philip Egerton's carefully prepared 

 catalogue, and might not be wholly unacceptable to the student in 

 Palichthyology. I therefore beg to subjoin it, and, in doing so, to re-
