a V pattern. The impressions of small rounded bodies seen in this 

 region upon the scales are considered to be eggs. 



The form of the skull and general relations of the bones will best 

 be gathered from Figs. 3 and 4. The osteological details are given by 

 the author at great length. The premaxillaries (im) are ornamented 

 with delicate long pits, and carry from 6 to 10 short pointed teeth, 

 which are larger than those in the maxillary bones and lower jaw ; 

 they are smooth and have a round pulp -cavity.

 Six times natural size. 



The maxillary (MS.), which is similarly pitted, and extends back 

 to the quadrato-jugal (QJ.), carries from 10 to 18 teeth. There are 

 probably two or three irregular rows of teeth behind these. The 

 nasal bones (N.) are notched in front to form with the premaxillary 

 bones the small nasal apertures, which they border on the inner side 

 with an elevated ridge. The lachiymal bone is absent. The 

 frontal bone (F.) is excluded from the circle of the orbit by the 

 triangular pT-efrontal bone (P.) in front, and the sickle-shaped post- 

 frontal bone (Pt. f.) behind. Its upper surface is covered with deli- 

 cate long pits ; and the post-frontal bone is strongly scnljatured. 

 The triangular post-orbital bone (Pt. o.) forms the outer and hinder 

 border of the orbit. The jugal ( Ju.) is a long bone which extends 

 back from the nasal and parallel to the maxillary, so as to form part 

 of the border of the orbit, and partly divide the quadrato-jugal (QJ.) 

 from the supratemporal (S.T.). Between the parietal bones (Pa.) 

 in the middle of the suture is the ovate or round foramen parietale,
