ADDENDA ET CORRIGENDA. 
All the following specimens were obtained from the neighbour-. 
hood of Lyme Regis : — 
P. 3650. Type specimen described and figured by Egerton, loc. cit. 
pi. vi. fig. 1. As proved by the next specimen, the 
caudal region is much shortened by crushing. A coarsely 
ornamented elongated plate of ill-defined outline, exposed 
between the hinder extremities of the mandible, is not 
improbably an infraclavicle. A portion of the jaws is 
shown enlarged in Egerton’s fig. 3, and some of the teeth 
are more highly magnified in fig. 4. Enniskillen Coll. 
P. 3651. Remains of fish about 0’6 in length, displaying the paired 
fins but otherwise very imperfect. Traces of the endo- 
skeleton are obscure, and the upper lobe of the tail is 
destroyed beyond recognition. Enniskillen Coll. 
P. 1333-34. T wo imperfect examples of thehead and abdominal 
region, the second showing the rays of the dorsal fin and 
noticed by Egerton, loc. cit. Both want the snout, but 
the first displays the hinder portion of the head and the 
opercular apparatus. The preoperculum is shown to 
extend over the cheek in the typical Palseoniscid manner; 
and there seems to be a small plate above the upper end 
of the operculum. Egerton Coll. 
P.558. Remains of head showing jaws, described and figured by 
Egerton, loc. cit. pi. vi. fig. 2. Egerton Coil. 
P. 3652. Imperfect right maxilla, dentigerous border of mandible, 
and preoperculum, exposed from the outer aspect. 
Enniskillen Coll.
