REMARKS. The genus Apateodus is only known by fragmentary material of the 
head region, thus making it difficult to place with any certainty. Its position close 
to the genus Ichthyotringa will be discussed in the consideration of the suborder 
Ichthyotringoidei as a whole (pp. 169-176).

DraGnosis (emended). Apateodus in which the head is large, with a pointed 
snout. Premaxillae small, toothed and laminate. Maxillae long and rod-like. 
Maximum depth of the mandible equalling one-fifth of its length. Large teeth on 
the palatines, ectopterygoid and dentary ; teeth much laterally compressed and 
marked with fine longitudinal striations. 
Horotyre. B.M.N.H. No. 49821, a small skull from the Turonian of Lewes in 
south-east England. 
MATERIAL. The holotype and specimen number 26241 in the Museum of the 
Institute of Geological Sciences, London: the latter specimen was prepared in acetic 
acid. This fine head had previously been described and figured by Woodward 
(1912: 246, pl. 54, fig. 4). Several specimens were examined in the Musée royal 
d’Histoire naturelle, Brussels, these being from the Maastrichtian deposits in 
Belgium and Holland. 
DESCRIPTION. Neurocranium. The neurocranium is shown in dorsal, ventral, 
lateral and posterior views in Text-figures 6-9. Posteriorly the neurocranium is 
broader than it is deep and gradually shallows anteriorly. The front of the neuro- 
cranium is acutely pointed, and the orbit occupies the central one-third of its length. 
The frontals form the major part of the neurocranial roof, meeting in the mid-line 
in a sinuous suture. Posteriorly the frontals contact the parietals, also in a sinuous 
suture. The frontals are flat medially, and relatively unornamented. More later- 
ally they bear several shallow longitudinal ridges which are more concentrated above 
the region of the supraorbital sensory canal. A shallow ridge passes anteriorly 
from the centre of ossification above the hind end of the orbit, and demarcates the 
lateral frontal region. This lateral region is curved to form the upper border of the 
orbit. The shallow ridge continues anteriorly to form the lateral edge of the neuro- 
cranium. The frontal above the orbit is curved, and anteriorly, on a level with the 
lateral ethmoid, there is a large supraorbital. The supraorbital runs antero-ventrally
