290 A. J. JUKES-BROWNE ON THE RELATIONS OF 



One fragment is preserved in the "Woodwardian Museum, and another 

 is in the cabinet of Mr. James Carter. A second species is re- 

 presented by a well-preserved portion of a whorl, to which the name 

 //. quadrituberculatus is attached, being, I suppose, a MS. name of 

 Mr. Seeley's ; it somewhat approaches H. Thurmanni, Pict. & Camp, 

 p. 118, but has wider interspaces between the rows of tubercles. 



Baculites Gaudini, Pict. & Camp. 



Baculites Gaudini, Pict. & Camp. Ste.-Croix, ii. p. 112, pi. lv. 

 f. 5-11. 



MM. Pictet and Campiche (p. 113) say they possess a specimen 

 from Cambridge belonging to the above species, and Mr. Etheridge 

 agrees with me in considering that most of the Cambridge specimens 

 belong to this form ; there are, however, some fragments which he is 

 inclined to refer to B. baculoides, Mant. Both are found in the Vra- 

 connien of Cheville (Renevier) ; but B. Gaudini is the commoner, and 

 is the only one found in the " Gault superieur " of Sainte-Croix. At 

 Folkestone it occurs, though rarely, in beds VI. and VII., or near the 

 top of the Lower Gault. It differs from B. baculoides in having 

 fewer and stronger ribs. 



Gasteropoda. 



Bucctnum: gaultinum, D'Orb. 



Buccinum gaultinum, D'Orb. Pal. Fr. p. 350, pi. 233. f. 1-2 ; Price, 

 Q. J. G. S. vol. xxx. pi. 25. f. 1-2. 



This species, which is well figured in the plate accompanying Mr. 

 Price's paper, is found in the Lower Gault of Folkestone, beds VII. & 

 VIII., but has not hitherto been recognized among the Cambridge 

 fossils. In the "Woodwardian collection, however, there is a Bucci- 

 noid cast, named Mostellaria, sp. ! ; and on comparing this with the 

 casts of B. gaultinum from the Gault, I found so close a resemblance 

 between them as to leave no doubt of their identity. It seems to be 

 rather a variable shell, and the Cambridge specimen belongs to one 

 of the more elongated forms. The casts of the Gasteropoda are not 

 at all easy to identify, and there are several species of so-called 

 Rostellariai still undetermined. 



Fusus quinouecostatus, Seeley. 



Fusus quinquecostatus, Seeley, Ann. &Mag. Nat. Hist. 1861, pi. xi. 

 f. 5. 



? Aporrhais Banctce- Cruris, Pict. & Camp. pi. 92. f. 4-5. 



This curious Gasteropod, which is certainly not an Aporrhais, but 

 may be a Fusus, appears to me identical with the figures of A. 

 JSanctce- Cruris from the Aptien of Sainte-Croix ; the general characters 

 are quite the same, and the five spiral ribs so characteristic of Mr. 

 Seeley's species are clearly delineated in the figures. Mr. Seeley's 

 name has the priority, should they prove to be the same species.
