DiaGNosiIs (emended). Emnchodus in which the length of the head exceeds its 
depth at the occiput ; maximum depth of the body behind the occiput estimated as 
equal to the length of the head. Dermal bones of the head ornamented with radiat- 
ing tuberculated ridges. Mandibular teeth six in number of which the anteriormost 
is the longest ; both hyopalatine and mandibular teeth long, thin and needle-like. 
Palatine tooth fractionally longer than the first tooth on the ectopterygoid. 
Mandibular symphysis much constricted ; mandible deepens posteriorly so that the 
maximum depth is equal to one-third of its total length. Maxilla long and thin and 
probably untoothed. 
SYNTYPES. Specimens in the B.M.N.H., numbers 4004, 4049, 4157, 4160, 4180, 
4181, 4183, 4184, 4198, being a collection of teeth and jaw fragments from the 
Turonian and Senonian of south-east England. 
MATERIAL. Specimens in the B.M.N.H. totalling some 20 fragmentary pieces, 
listed by Woodward (Ig0I : 192). 
REMARKS. The type species is only known by imperfect specimens of the head. 
The series of type specimens are those figured by Mantell (1822) and Agassiz (1837), 
all from the Chalk of Sussex. The following description is based mainly on 
specimen number 4oor in the B.M.N.H. from the Middle Chalk of Lewes in Sussex, 
described by Woodward (1901 : 192) as a very imperfect small skull. The specimen 
was prepared in acetic acid and a small practically complete neurocranium was 
obtained. The description of the jaws was compiled from several fragmentary 
specimens, notably specimen number P.5415 which had already been partially 
described and figured by Woodward (1888a : 315, pl. 1, fig. 5).
