CRETACEOUS FISHES. 371 
Genus Phacodus', new, Dixon. 
Phacodus punctatus, R. 4. (Tab. XXX. fig. 16.) 
The name of the genus is taken from the kidneybean-shaped character of the 
teeth. 
The teeth are smooth and worn down in the centre; they are easily distin- 
guished from the Pycnodontes. They show the remains of calcigerous tubes in 
small dots and punctures. This is the only specimen I have seen. It forms 
part of my own cabinet, and was found near Lewes. 
Notes on the Order Ctenoidei. 
Family Perc. 
Genus Beryz. 
The genus Beryx was formed by Cuvier, and is allied to Holocentrum and 
Myripristis. 
Beryx ornatus, V.C. (Tab. XXXVI. fig. 3; Tab. XXXIV. figs. 1,4&5. 
Vol. iv. p. 115, Agassiz.) 
Zeus Lewesiensis, Mantell. 
This is a very common fish in the upper and lower chalk : it is found in great 
perfection in Kent and Sussex, and other counties of England, and on the Con- 
tinent. I possess fine specimens from Houghton and the pits in that neigh- 
bourhood : the quarrymen at Lewes call this fish ‘ Johnny Dorey.’ 
Beryx radians, R. (Tab. XXXVI. fig. 4. Vol. iv. p. 118, Agassiz.) 
This species is not so large as the former, but is longer in proportion; it is 
generally found in the lower chalk and chalk marl; the scales are particularly 
shining and pectinated, smaller than those of B. ornatus and of a dark colour. 
This fish is more rare than B. ornatus, but I have seen good specimens from the 
pits near Amberley, Steyning, Washington, Lewes and Clayton.
