ENCHODONTIDiE. 
21J 
Genus PAXi-ffiOLYCUS^ W.. von der Marck. 
[Palaeontogr. vol. xi. 1863, p. 31.] 
Trunk much elongated, both this and the head laterally com¬ 
pressed. Ja’ws and dentition as in EncJiodus and Euryjjholis. 
Vertebrae at least 70 in number, nearly half abdominal; the centra 
longer than deep, constricted mesially, and strengthened by at least 
one lateral longitudinal ridge. All except the foremost rays of 
each fin finely divided distally, but none excessively elongated. ISlo 
postclavicular plate. Pectoral fins rather large ; pelvic fins very 
small; dorsal fin also very small and remote, with one spine and 
about 8 divided rays, opposed to part of the much-extended anal 
fin, which has nearly 50 rays; caudal fin small and deeply cleft, 
with stout basal rays. A series of median dorsal scutes immediately 
behind the occiput, [but no other dermal covering hithertO' 
observed].

Type. Nearly complete fish; Academy of Miinster. 
The type species, attaining a length of about 0-4. Maximum 
depth of trunk contained about ten times, and length of head with 
opercular apparatus nearly eight times in the total length of the 
fish. Enlarged teeth longitudinally striated. Vertebrae 75 in 
number, about 32 referable to the abdominal region; the centra 
slightly pierced by persistent notochord. Pelvic fins arising slightly 
behind the middle point between the pectoral and anal fins; dorsal 
fin arising considerably behind the anal, but opposed to part of the 
anterior half of the latter, comprising one spine and 8 divided rays, 
the spine not much shorter than the first divided ray ; anal fin 
extending along nearly the whole of the caudal region, with about 
46 well-spaced divided rays, apparently no anterior spinous rays. 
Dorsal scutes perhaps about 6 in number, ornamented with fine 
radiating ridges. 
Form, ^ Loc. Upper Cretaceous: neighbourhood of Sendenhorst, 
Westphalia. 
Not represented in the Collection. The above diagnoses are 
based especially upon the second specimen in the Academy of 
Munster described by W. von der Marck, loc. cit. 1885.
