LARIOSAURTD^. 285 



Genus NEUSTICOSAURUS, Seeley \ 

 Syn. (?) Pachypleura, Curioni 2 . 



Cervical ribs either very small or absent; humerus (at least 

 typically) with a distal foramen ; epipodials very long and slender ; 

 phalangeals of pes long and slender. 



The characters by which the type of Pachypleura differs from 

 that of the present genus do not appear to be of more than specific 

 value, although the figured specimens do not show whether the 

 humerus had a foramen. 



Neusticosaiirus pusillus (Fraas 3 ). 

 Syn. Simosaurus iimillus, Fraas * 



The type species. Skull comparatively short and wide; neck 

 relatively long. Length of head and body to root of tail about 0,215 

 (8-5 inches) ; length of skull 0,030 (1*17 inches) ; length of humerus 

 0,022 (0-88 inch). 



So far as the writer can see, the skeleton of Neusticosaiirus {Pacliy- 

 pleura) edwardsi, Curioni B , only differs from that of the present 

 form by its more slender skull and larger neck, the other distinc- 

 tions mentioned by Deecke not being apparent. 



Hab. Europe (Germany). 



R. 53. Slab showing the ventral aspect of the greater portion of the 

 (Fig.) skeleton ; from the Lower Keuper or Lettenkohle ° of 

 Hoheneck, near Ludwigsburg, north of Stuttgart, Wiir- 

 temberg. One of the types ; figured by Fraas in the 

 'Jahresh. Yer. Nat. Wiirtt.' vol. xxxvii. pi. i. fig. 1, and 

 also by Seeley in the ' Quart. Journ. Geol. Soc' vol. xxxviii. 

 pi. xiii. fig. 1 ; the limbs of the right side being figured 

 on an enlarged scale on pp. 362 and 364 of the latter 

 volume. The greater part of the caudal region and tho 

 whole of the left pelvic limb are wanting ; but, with tho 

 exception of some imperfection in the other limbs, the

 derived from Kcustikos is not a synonym of Keustosaicrus, Raspail, ' Sur un 

 Saurien fossile,' Paris (1842), which comes from Nemtes.
