Fish Vertehrce. 



The vertebrae of LamncB are not rare in the "Lower Tertiary 

 Sands," and with them occur in rather greater abundance the vertebrse 

 of some osseous fish, one of which is here figured (Pl. III. fig. 2) 5 

 many of them are, however, of a much smaller size. 



Fish-scales. Pl. III. figs. 2*, 2**. 



These are the large scales of some Cycloid ? fishes, to which pos- 

 sibly the last-mentioned vertebrae may also be referred. "With these 

 are found smaller scales of similar character, and a few veiy small 

 conical teeth belonging probably to the same class of fishes. Loca- 

 lities : Woolwich and Sundridge. 



Cycloid scales and fish-bones occur also at Counted Hill, in the 

 Paludina-bed. 



Bird Remains. 



A very interesting specimen of a small, irregularly cylindrical 

 bone, about half an inch in length, discovered by the Rev. H. M. De 

 la Condaminp at Counter Hill, whilst these pages were passing 

 through the press, has been determined by Prof. Owen, who has 

 kindly examined it, to be the first phalangeal bone of the foot of a bird. 

 It is the only such specimen found. [J. P., Jun., April 10, 1854.] 



Seseriptions of some New Species of Shells front the " Wool- 

 wich AND Reading Series." By John Morris, F.G.S. 



Cardium Laytoni, n. sp. Pl. II. figs. 1, 2. 



Testa trigocali, inaequilaterali, postice subangulata, obliquata, costata; 

 costis numerosis, planulatis ; margine dentate ; umbonibus incurvis, ap- 

 proximatis. 



A trigonal, inequilateral, and somewhat oblique shell, with the pos- 

 terior portion slightly angulated ; the surface is marked with nume- 

 rous flattened ribs and linear interspaces, which become more distinct 

 and separated on the posterior angulated side ; the margins are 

 strongly dentated. This shell is distinguished from C. Plmnstead- 

 iense by its smaller size, more uniform marking, and the posterior 

 side not being so much produced or angular. 



The specimen figured was found at Richborough by the Rev. J. 

 Lay ton, of Sandwich, after whom the species is named. 



CoRBTJLA ReguLbiensis, n. sp. Pl. II. figs. 4, 5. 



Testa ovato-transvers^, subgibbosa, rostrata ; striis tenuissimis irregularibut 

 ornata. 



, , var. /3. Pl. II. fig. 6. 



Testa irregulari, vix rostrata. 



An ovate and somewhat quadrangular shell, with the posterior 

 margin but very slightly produced, except in the variety from Heme
