Ralph Tate — New Liassic Fossils. 203 



In the present imperfect state of my knowledge of the 

 numerous similar European forms, I have thought it only advisable 

 to give a list of the species known and described, and to state that 

 the pterygoid processes or wings of those mentioned below are more 

 expanded, and are attached to a greater portion of the spire, than 

 those just described, and are none identical with the English forms. 

 List of species from the Chalk figured by continental authors 

 allied to A. Mantelli : — 



R. acutirostris, Pusch, 1837; Geinitz, 1839. 



R. gigantea, Geinitz, 1839. 



R. megaloptera, Reuss. 



JR. papilionacea, Goldfuss, Geinitz, Reuss, etc. 



R. emarginulata, Geinitz, 1850. 



A. stenoptera, Goldfuss, 1843. 



A. Reussi, Geinitz, 1842. 



Buccinum turritum, Roemer, 1841. 



Several species from Gosau may be included in this group. B. 

 costata and granulata, Sow. ; B. digitata and crebricosta, Leheli ; 

 B. Partschi, Leh. ; B. passer, and several undescribed species in the 

 Museums at Dresden, Vienna, Munich, etc. A. glabra, and A. 

 Bobinaldina, from Atherfield, must also not be omitted from the 

 list. 



EXPLANATION OF PLATE VI.

wing. From the author's cabinet. 

 Fig. 2. — A young specimen showing growth of wing. From the author's cabinet. 

 Fig. 3. — Specimen having thin and linear ribs to the last whorl. This variety occurs 



in an upper bed at Folkestone. In the British Museum. 

 Fig. 4.— Aporrha'is Par kinsoni, Folkestone. Full grown. From the author's cabinet. 

 Fig. 5. — A younger specimen, with immature wing. From the author's cabinet. 

 Figs. 6 and 7.— Specimens from Blackdown. In the British Museum. To show 



variations in size and ornamentation. 

 Figs. 8 and 9.— Aporrha'is Mantelli, from the Grey Chalk, Folkestone. The original 



in the author's cabinet. 

 Fig. 10. — Aporrha'is Mantelli, var. sub-tuberculata. From the Chalk Marl near 



Devizes. In the British Museum. Part of the spire has been left out for want 



of space.

III. — On Some New Liassic Fossils. 

 By Ralph Tate, Assoc. Lin. Soc, F.G.S., etc. 



ME. T. BEESLEY, in a " Sketch of the Geology of the Neigh- 

 bourhood of Banbury," 2nd edit., 1873, published a very 

 extensive list of Liassic fossils, and having been honoured by the 

 loan of many of them, the majority in an excellent state of preserva- 

 tion, I beg to record the presence of a few interesting forms, and to 

 describe some new species. The following include some species that 

 have not been hitherto noticed, and others that are little known in 

 Britain : — Notidanus amalthei, Oppel ; Pleurotomaria mirabilis, Des- 

 long. ; Trochus AEgion, D'Orb. ; Phasianella turbinata, D'Orb. ; 

 Pleurotomaria helicinoides, Bom. ; Onustus heliacus, D'Orb. ; Limea 

 cristata, Dumort. ; Mytilus Aviothensis, Buvignier ; Spiriferina, oxy- 

 gona, Bur. ; and Siderolites SchloenbacMi, Brauns. The last is placed 

 among the Foraminifera by its describer, but it seems to me to be a 

 Neurofungia.
