ACTINOPTERYGII. 
32453-63, 32465-71, 32583. Series of eighteen specimens, one 
being in counterpart, illustrating all the principal features 
in the skeleton of this species ; Curcy, Normandy. 
Tesson Coll. 
P. 947-8. Six similar specimens ; Curcy. Egerton Coll. 
28855. Three imperfect fishes, two being in counterpart, and also 
one head ; Alderton, near Cheltenham. Purchased , 1854. 
P. 3667. Contorted fish; Ilminster, Somersetshire. 
Enniskillen Coll. 
32583 a, b. Two very small specimens (one being in counterpart) 
with relatively large head, probably to be regarded as 
young of this species; Curcy. Tesson Coll. 
The following specimens of Leptolepis from the Upper Lias of 
Dumbleton, Gloucestershire, represent the form named L. concen- 
tricus by Egerton (Quart. Journ. Geol. Soc. vol. v. 1849, p. 35, and 
Pigs. & Descript. Brit. Organic Remains, dec. vi. 1852, no. 9). This 
is said to be distinguished from the so-called L. constrictus (identified 
above with L. bronni) by its relatively larger head, thicker scales, 
and smooth preoperculum; but, judging from present evidence, it 
seems likely that all these differences will prove to be merely due 
to differences in the state of preservation. The type specimen is in 
the Collection of Rev. P. B. Brodie, Rowington. 
P. 940. Imperfect fish and six fragments, labelled Leptolepis con - 
centricus in Egerton’s handwriting. The preoperculum in 
the best specimen is smooth, but probably does not exhibit 
the outer layer, and the corresponding bone in two of the 
fragments shows distinct indications of the superficial 
radiating ridges. Egerton Coll. 
39150-52. Three imperfect specimens. Bowerbank Coll. 
P. 3666. Five similar specimens, two exhibiting traces of the ra¬ 
diating ridges on the operculum. Enniskillen Coll. 
P. 6145. Greater portion of fish and a detached head. 
Purchased , 1890. 
P. 7038. Seven fragmentary specimens, one being in counterpart, 
exhibiting the form of various bones. Purchased , 1894.
