F. 3443. Well-preserved specimen displaying all the fins, shown, ot 
the natural size, in PL XYI. fig. 7 ; Wallyford, near 
Edinburgh. The head exhibits the dorso-lateral aspect, 
and the bones are seen only as impressions of their 
external surface. The fins consist of broad, longitudinally 
ribbed rays, closely articulated and distally branching ; 
and there are prominent fulcra. The pelvic fins are some¬ 
what inferior in size to the pectorals, and even the 
foremost rays of the latter are distinctly articulated. The 
dorsal and anal fins are about equal in size, and the latter 
arises opposite the hindermost rays of the former. The 
upper lobe of the tail is wanting distally, but the caudal 
fin is well preserved and exhibits its bifurcation. Except 
upon the upper caudal lobe, the scales are all displaced, 
but their general proportions are recognizable.
