1897] RESTORATION OF EXTINCT REPTILES 191 
- grams, in black lines on a white ground, executed by Miss G. M. 
Woodward with the artistic skill and excellence of technique which 
invariably characterise her work. 
The species chosen to represent the Order Ornithosauria is 
Dimorphodon macronyx, from the Lower Lias of Lyme Regis (Fig 1). 
Owen’s well-known restoration of this species (“ Liassic Reptilia,” 
Mon. Pal. Soc., 1870, pl. 20., and “Hist. Brit. Foss. Rept.,” 1849-84, 
vol. iv., pl. 17), naturally formed the basis of the diagram, but 
the shapes and proportions of the bones were taken from the 
actual specimens, of which the Geological Department of the 
museum can boast a good many.’ The correctness of Owen's 
restoration of the pelvis was severely criticised by Seeley in 1891

recourse was had to figures 11 and 13 of this paper when drawing 
the pelvic region of the skeleton. The pteroid bone, or backwardly 
directed metacarpal of the rudimentary thumb, which is incorrectly 
shown on the ulnar side of the limb in Owen’s figure, was in- 
troduced from the specimen (R. 1034) in the Geological Gallery, 
and the details of the caudal vertebrae from specimen (41546), 
figured by Owen in the “ Liassic Reptilia” (pl. 19, fig. 4). Since the 
back part of the skull is crushed in the Natural History Museum 
specimens of Dimorphodon, the outlines of the quadrate bone and 
the supra-temporal and lateral temporal fossae were added from

and others, and references to the descriptions and figures are to be found in the Brit.
