Soc' vol. xl. pis. xvi., xvii., all the figures being reversed. 

 In the figure of the palate (pi. xvii. fig. 1) the aperture 

 marked vc is a fracture. The median bone which Owen 

 terms the palatine is more probably the anterior extremity 

 of the parasphenoid ; while it is probable that at least a 

 considerable portion of the bones termed vomers represent 

 the palatines. If this be so the structure of the palate 

 will approximate very decidedly to that of Nyrania. 

 The absence of a postarticular process to the mandible is 

 well shown ; in the figure too short a space is allowed for 

 the missing portion of the ramus. 



By exchange with the Blomfontein Museum, 1884. 



R. 503. Four fragments of bones of the cranium apparently referable 

 to this species, and probably associated with the preceding 

 specimen : from Beersheba. One of these specimens in- 

 cludes a bone which appears to be the greater portion of 

 the quadrate, attached to which are fragments of two 

 other bones.

Incertce sedis. 

 Genus PHOLIDOGASTER, Huxley \ 

 Yery imperfectly known, the frontal aspect of the skull being 

 concealed in the type. There is complete ventral armour; the 

 ventral surface of the vertebrae closely approximates to that of 

 Sjphenosaurus, and suggests that the present genus indicates an 

 allied rhachitomous type. 



Pholidogaster pisciformis, Huxley 2 . 

 The type and only described species. Length of skull about 

 0,177 (7 inches) ; total length of skeleton about ] ,116 (44 inches). 

 Hab. Europe (Scotland). 



30534. Slab of shale showing the ventral aspect of the skeleton ; 



(Fig.) from the Lower Carboniferous of Gilmerton, near Edin- 

 burgh. The type specimen ■ figured by Huxley in the 

 ' Quart. Jo urn. Geol. Soc' vol. xviii. pi. xi. figs. 3, 4. 

 The mandible, lateral thoracic plates, ventral armour, and 

 the ventral aspect of the later thoracic vertebrae are well 

 shown. The contour of the vertebrae so strongly resembles 

 that of Sphenosaurus as to suggest that they are really 

 intercentra. Purchased, 1856.
