86 ICHTHYOPTEETGIA. 



aspect ; the left pelvic limb is beneath the vertebral 

 column. This specimen may have belonged to the next 

 species. No history. 



2009 *. Slab showing an oblique frontal and left lateral view of the 

 (Fig.) somewhat crushed skull of an immature individual ; from 

 Street. Figured by Hawkins in his ' Sea Dragons,' pi. xiii., 

 and also by Owen in his 'Liassic Reptilia,' pt. iii. pi. xxxii. 

 fig. 2. (In the latter figure the scale is J instead of -J- as 

 stated in the description.) The length of the rostrum is 

 about four times the diameter of the orbit. The teeth are 

 present, although displaced from their groove, throughout 

 the length of the jaws : they are drawn relatively too large 

 in Owen's figure. HaivMns Collection. 



R. 1128. A full-sized skull, wanting the greater portion of the 

 rostrum, and with the fronto-nasal region crushed in, and 

 the orbits in consequence abnormally elongated antero- 

 posteriorly ; probably from the Lower Lias of Lyme-Regis. 

 This specimen seems 'to agree exactly in size with the 

 corresponding portion of the skull of No. R. 1120. Al- 

 though its crushed condition interferes with accurate 

 comparison, the large and flattened parietals are well 

 shown ; the straightness of the facial profile is probably 

 due to crushing. The posterior teeth still remain. 



No history. 



40348. Slab showing the crushed skull of an immature individual ; 

 from the Lower Lias of Lyme-Eegis. Purchased, 1867. 



24300. Plaster slab showing the ventral aspect of a very similar

 The conjoint atlas and axis are preserved between the 

 mandibular rami. Purchased, 1849. 



2160 *. Slab showing one lateral aspect of the middle portion of the 

 rostrum ; probably from the Lower Lias of Street. The 

 teeth are in beautiful preservation. Haivkins Collection. 



2012 *. Slab showing the anterior portion of the caudal region of the 

 {Fig.) vertebral column, the dorsal aspect of the disjointed right 

 pelvic limb, fragments of the left do., and a few bones

 Lias of Street. Figured by Hawkins in his ' Sea Dragons/ 

 pi. xvi. Same history.
