allying it to P. lonr/ispinus, Sow., P. scahrinihis, Mart., and P. un- 

 (iatus, Dcfr. He was not prepared to describe it as a- distinct 

 species, but suggested for it the name of Productus complectois, in 

 allusion to its embracing habit, in case of its proving to be distinct. 

 The f'^pinferina described by the author. was compared by him 

 with S. cristata, Schl., var. ortoplicata, Sow., and with S. insculpta, 

 PhilL, from both of which it differs in certain characters ; but as 

 only one specimen has been met with, he refrained from founding a 

 new species upon it. The specimen is from Fullarton Quarry, near 

 Temple, Edinburghshire. 



" Notice of the Occurrence of Remains of a British fossil Zeuglodon 

 (Z. Waukh/ni, Seeley) in the Barton Clay of the Hampshire coast." 

 By Harry Govier Seeley, Esq., F.L.S., F.G.S. 



In this paper the author described the remains of a species of 

 Zeufjlodon obtained by the late Dr. A. Wanklyn from the Barton 

 Cliff, consisting of a great part of the skull, about the same size as that 

 of Zeuglodon brachi/spondi/lus, Miiller. The bones preserved are the 

 maxillary, frontal, and parietal bones. The left maxillary sliows 

 the remains of five teeth in a length of rather less than seven inches, 

 the first two of which had simple conical crowns and a single fang ; 

 the sockets of these are elliptical. The third tooth is considerably 

 compressed, with a sharp margin, which has four small denticles on 

 each side of the large median denticle. The following teeth exhibit 

 somewhat similar characters, and each possesses two fangs. A 

 single tooth, resembling the canine of a Carnivore, was found with 

 the specimen, and was probably one of those missing from the first 

 sockets. The characters of the bones of the head were described in 

 more or less detail : the frontal region is flattened, with a sharp 

 crest continued along tlie parietal region, as in Z. hracJu/sjwndi/lus ; 

 but the crest is not flattened posteriorly into a narrow table, as in 

 that species, iior is the parietal united with the frontal by a folded 

 suture. The species, named Z. Wanl-h/ni in memory of its dis- 

 coverer, differs from all known species of the genus in the shortness 

 of the interspaces between the teeth. 



" On the Remains of Emys hordweUensis, from the Lower Hord- 

 well beds in the Hordwell Cliff'." By Harry Govier Seeley. Esq., 

 F.L.S., F.G.S. 



The remains described by the author consist of some fragments 

 constituting the greater part of the plastron and carapace of a species 

 of Emys obtained from a bed in Hordwell Cliff' about 20 feet below 

 that which has yielded the chief remains of Crocoddna Hastingsia;, 

 and about 1 feet above the brackish-water Upper Bagshot iDcds. 

 The preserved portion of the carapace is 9 inches long; when per- 

 fect it was probably about 12 inches long and 10 inches broad. Its 

 distinctive characters were said to be : — the broad, short gular scute, 

 with sinuous sutures ; the subtriangular nuchal scute ; the subpen- 

 tagonal first vertebral scute, broader than the succeeding quadrate
