edge of the maxilla; and there are impressions of a 
ceratohyal and the large gular plate between the rami of 
the mandible. Two or three enlarged scales in the region

35580-82. Part of the abdominal region with dorsal fin, another 
specimen showing part of the head and abdominal region, 
and an imperfect detached caudal fin; Whitby. The 
number of rays in the dorsal fin is difficult to ascertain, 
but there appear to be slightly more than 20. The form 
of the suboperculum is well shown in the second specimen.

in part much fractured; Ohmden, near Boll. A large 
upper postclavicular scale is conspicuous, and the smooth¬

anterior flank-scales exhibit feeble traces of elongated 
tubercles replacing delicate vertical folds at the anterior 
border. Purchased , 1861.

of the broad branchiostegals and remains of the gular 
plate are conspicuous, all quite smooth. Enniskillen Coll.
