In different individuals the scale sculpture shows very considerable 

 differences as regards the strength and prominence of the scale- 

 markings, the sculpture being much more pronounced in the case 

 of some individuals than in others where the scales seem almost 

 smooth. Another point of interest is that in the young fish the 

 ventral scales do not appear to be so low and narrow as they 

 are in the more adult fish. The fish, a young one, which has 

 been carefully figured above, shows this well. 



YIL — Note on a Tortoise from the Wealden of the Isle of 



Wight. 

 By Reginald W. Hooley, Esq. 



IN May, 1897, a fossil tortoise was found about 10 feet above low 

 water-mark opposite Shepherd's Chine, by Mr. Wm. White, of 

 Atherfield, Isle of Wight. It came into my possession in July of 

 last year (1899). At that time the only portions clear of matrix 

 were the sixth, seventh, and eighth costal bones, the edges of the 

 marginals, and the epi- and hyoplastrals nearly to the notch ; the 

 matrix is a fine silt containing much iron. The specimen had been 

 subjected to long attrition by the sea. A very thin but hard seam of 

 whole and broken Paluclina had offered a stubborn resistance, as 

 likewise it did against a finely pointed and tempered chisel. On 

 the surface of the carapace are several Cyprids (sp. ?) and the 

 impression in section of Paludina. 



The carapace is somewhat distorted and flattened ; in its present 

 state it measures 12^ inches long from A to B and 14f inches wide 

 from G to D ; in life its shape was probably ovoid. A semicircular 

 piece of the fifth costal on the left side and the greater portion of 

 the posterior costals, the pygals, and posterior marginals have been 

 destroyed by the sea subsequent to the fall of the specimen from 

 the cliff, but in other respects it is remarkably complete. 



The neurals, eight in number, are narrow and elongate, some 

 being twice as long as broad. There are eight costals, of which the 

 second, third, and fourth have been depressed beneath the rest of the 

 carapace to the extent of their thickness, and outer ends of the first 

 and fifth left costals, moreover, have been forced under the marginals. 

 The nuchal is emarginate and seems to be divided ; there are eight 

 marginals on the right, with a portion of the seventh and eighth 

 wanting, and seven on the left, with but part of the seventh remaining.
