GALESAURID M. i O 



distinguished from the preceding. Sections are seen of 

 the four incisives and also of the tusks of the mandible. 

 The serration of the posterior edge of the upper tusks is 

 also well shown. Presented by A. G. Bain, Esq., 1853. 



47065. Mass of rock, showing either portions of the bone of the 

 (Fig.) inner layers of the skull or their impression ; from the 

 Karoo system of Styl-Krantz, in the Sneewberg range. 

 Figured by Owen in his ' Catalogue,' pi. xvii. figs. 5, 7, 8. 

 The impression of the first incisiform tooth of the left 

 side exhibits the serrations on its posterior border very 

 clearly, and also the greater length of this tooth as com- 

 pared with the next one.

47310. The nearly entire left humerus ; from Mildenhalls. This 

 {Fig.) specimen appears to have belonged to the same individual 

 as No. 47309. It is figured by Owen of half the natural 

 size in the ' Quart. Journ. Geol. Soc' vol. xxxii. pi. xi. 

 figs. 6-9, from the palmar and dorsal aspects and the two 

 extremities ; and also of the natural size from the palmar 

 aspect in his ' Catalogue,' pi. xix. fig. 1.

. Genus 2ELUROSAURUS, Owen \ 



Incisive teeth t^E^^ ', cheek-teeth g, with compressed and back- 

 wardly curved crowns having serrated posterior edges ; premaxillary 

 teeth also serrated posteriorly. Skull vaulted, with the facial por- 

 tion deep, and typically of considerable length ; size of temporal 

 fossa unknown ; direction of orbits mainly lateral ; postorbital bar 

 inclined downwards and backwards. Superior surface of mandibular 

 symphysis sloping obliquely upwards. 



So far as regards the anterior dentition there appear to be no 

 characters by which this genus can be distinguished from the pre- 

 ceding, so that its right to stand has yet to be proved. 



JElnrosaurus felinus, Owen 2 . 



The type species. Considerably larger than Galesaurus planiceps, 

 but entire length of skull unknown. Premaxillary teeth five in 



1 Quart. Journ. Geol. Soc. vol. xxxvii. p. 261 (1881).
