Pseudoeleginus intermedius , P. jonas , and P. majori are merely 
names for undetermined fishes from the Upper Miocene of Gabbro, 
luscany (de Bosniaski, Atti Soc. Tosc. Sci. Nat. — Proc.-Verb. vol. i. 
1878, p. xix). 
The aberrant family of Lornnn.R seems to date back to the 
Eocene period, but is not represented by any fossils in the Collection. 
The extinct species described as follows seems to be rightly placed 
here: — 
Lophius brachysomus , L. Agassiz, Neues Jahrb. 1835, p. 292, 
and Poiss. Foss. vol. v. pt. i. (1839-44), p. 114, pi. xl. 
Lophius piscatorius, G. S. Volta, Ittiolit. Veronese (1796), 
pi. xlii. fig. 3 {errors). Loricaria plecostomus, G. S. Volta, 
ibid. pi. xx. fig. 4 {err ore). — Upper Eocene ; Monte Bolca. 
[Imperfect fish; Paris Museum of Natural History.] 
The name Lophius patayonicvs has been given to undescribod 
teeth from the supposed Cretaceous of Patagonia (F. Ameghino, 
Sinops. Geol.-Paleont. — Suplem. 1899, p. 10). 
Division G. BLENNIIFORMES. 
Pectoral fins with much extended-baso on flank ; pelvic fins j ugular, 
reduced or absent. Dorsal fin-spines numerous but usually flexible. 
No bony stay between circumorbital ring and preoperculum. 
Synopsis of Families represented by Extinct Genera. 
Bony scutes on trunk ; snout produced Blochiid^e (p. 591). 
No bony scutes; snout not produced Bi/enniid.® (p. 595). 
Family BLOCHIID^E. 
Elongated fishes with slender caudal pedicle ; snout much pro- 
duced; mandibular suspensorium nearly vertical and gape very 
wide. Abdominal vertebrae without transverse processes, but 
bearing small ribs. Dorsal fin consisting only of flexible spines 
and occupying nearly the whole of the back ; anal fin also much 
extended ; caudal fin more or less expanded. A covering of bony 
scutes. 
Known only by one genus of Eocene age.
