The somewhat imperfect shell: from the Wealden of the {Fig.) Isle of Wight. The type specimen (fig. 44). Noticed by G. A. Boulenger and the present writer in the' Geol. Mag.' dec. hi, vol. iv. p. 272, and provisionally referred to P. sanctce-vcrence, and also by the present writer in the ' Quart. Journ. Geol. Soc.' vol. xlv. p. 238 (as No. 28976). The whole of the marginals are wanting, and the edges of the costals and plastron have been somewhat waterworn. The width of the second vertebral shield is equal to the length of that shield plus rather more than half that of the third vertebral, whereas in the type of P. sanctce- verence the former diameter is relatively greater when compared with the length of the corresponding shields.
