Type. Imperfect skull, with dentition ; Brighton Museum. 
A small species, with teeth very irregularly arranged. Teeth of 
the principal series on the splenial bone obliquely set, very irregular 
in size and shape, wide mesially, tapering at each extremity, and 
not much broader than long ; inner teeth relatively large, in one 
series, usually broader than long, with axis oblique; outer teeth in 
about three very irregular series, mostly smaller than the teeth of 
the inner series. Yomerine dentition anteriorly in three series, 
posteriorly in five, but extremely irregular ; the largest teeth much 
antero-posteriorly elongated and comprised in the outermost series. 
Nearly all the teeth indented, the smaller ones having the pit 
especially conspicuous and surrounded with a crenulated margin. 
Form. Sf Loc. Turonian: Sussex. 
Not represented in the Collection. The type and only known 
specimen, from the Lower Chalk of Glynde, is preserved in the 
"Willett Collection, Brighton Museum, and is important as exhibiting 
some features in the cranial osteology of the fish. The vomer is 
single ; the mandibular suspensorium is strongly inclined forwards ; 
the pterygo-palatine arcade is delicate, toothless, and fused through¬ 
out the greater part of its length with the base of the skull; the 
parasphenoid has a deep inferior lamellar keel; the articulation of 
the mandible is very deep and narrow; and there is a large super¬ 
ficial bone apparently to be identified with the preoperculum.

Type. Splenial dentition ; Ubaghs Collection, Maastricht. 
A species somewhat smaller than the type, known only by the 
splenial dentition. Teeth of the principal series on the splenial 
bone scarcely arcuated, blunt at each extremity, attaining a breadth 
more than three times as great as their length, and usually sub¬ 
divided into small teeth in the anterior part of the bone; inner 
teeth very small, in two irregular series; outer teeth equally small, 
in three or four irregular series.
