utmost liemi-heteroccrcal. The dorsal and anal fins show also different 
characters from those in Platysomus, so much so that, in Zittcl’s “ Ilandbuch 
der Palmontologic ” (1SS7, p. 245), it is placed, though with a query, with 
the Pycnodontkhc. This appears indeed to he rather probable.*

[* In tliis criticism Dr. Feistmantel lias quite overlooked the opinion of my friend, Dr. Ramsay II. Traquair, 
who makes tlie following remarks on Cleithrolepis-. — “There only remains the very imperfectly known genus 
Cleithrolepis, Egerton, .... and which, to certain points of resemblance to Flatysomus, adds tlie peculiarity of 
having a homocercal tail.” (Ann. and Mag. Nat. Hist., 1875, XV, p. 205. — R.E., jun.)]
