CORRIGENDA AND ADDENDA TO PARTS I. & II. 



Part I., p. 95, fig. 14, la = prefrontal. 



98, line 9 from bottom, for Aix read Ain. 



103, line 13 from bottom, for hughi read hugii. 



104, line 12 from top, for pi. xii. read pt. 3, pi. xii. 



109, line 6 from top, for latest read largest. 



132, fig. 19. It appears that the nares in Diplodocus were not 

 situated on the vertex of the cranium, as in this fig., but 

 formed slits in the anterior region as in Pterodactyles. 



140, line 7 from top, for 10390 read 2544. 



145. The length of the femur of Atlantosaurus is 1,880 (74 inches), 

 instead of that given in the text, which is taken from the 

 original description. 



153, note 4, for 400 read 440. 



179, fig. 32, for armatus read ungulatus. 



185, note I, for 1834 read 1833. 



199, line 12 from bottom, for E. 640 read E. 604. 

 „ line 8 from bottom, for 0,870 read 0,923. 



200, line 14 from bottom, for extension read expansion. 



297, fig. 67. It appears that the forked extremities of the mandible 

 of Hyperodapedon did not embrace the premaxilla?, as in 

 Huxley's restoration, but that they were received in the pit 

 on the oral surface of the palate, as in Chelydra. 

 Part II., p. 6, line 8 from top, for which are read the secord of which is. 



50. No. E. 224 is described and figured by Owen in his ' History 

 of British Fossil Eeptiles,' Ichthyopterygia, p. 176, pi. xxx. 

 fig. 2 (1884), as Ichthyosaurus longimanus, of which it is the 

 type. The structure of the paddle closely resembles that of 

 I. communis, No. 2001* (p. 44), and also that of I. breviecps, 

 No. 43006 (p. 52), and it is probable that the specimen 

 belongs to one of those forms. In Owen's description the 

 specimen is incorrectly stated to be from Barrow. 

 50. No. E. 1063 is described and figured by Owen, op cit. p. 176, 

 pi. xxx. fig. 1, as I. fortimanus, of which it is the type. It 

 is probable that this specimen, which is from Barrow-on- 

 Soar, is really referable to I. inter medms, since it approxi- 

 mates very closely in contour to the pectoral limb of 

 No. 14565 (p. 56), with the exception that there are only 

 three bones in the proximal portion of the third transverse 

 row — a variation which may well be due to an individual 

 peculiarity. 



110. No. 43166 is from Boulder Clay at Muswell Hill, Middlesex, 



and therefore not improbably belongs to one of the Post- 

 Liassic species. 



129, fig. 39, for anterior read posterior. 



284-286. Bassani, Atti Soc. Ital. Sci. Nat. vol. xxix. pp. 21-24 

 (1886), identifies Macromcrosaurus plinii with Lariosaurus 

 balsami, and also refers Xcusticosaurus to Lariosaurus, but 

 regards Tachypleura as distinct. Dactylosaurus gracilis, 

 Giirich, Zeitschr. deutseh. geol. Ges. vol. xxxvi. p. 125 

 (1884), from the Muschelkalk of Silesia, almost certainly 

 belongs to this group. 



299. Add : — Notkoscmrus latifrons, Giirich, op. cit. p. 132; Mus- 

 chelkalk, Silesia. 



300. Mesosaurus dates from Comptes Eendus, vol. lx. p. 950 

 (1865).
