sippi, have been named Ololithus (Triglot) cor (it. Koken, Zeitschr. 
deutseh. gcol. Ges. vol. xl. 1888, p. 287, pi. xviii. fig. 10). Others 
from the Oligocene of Germany have been named Ololithus ( Trigla ) 
ellipticus, 0. ( Trigla ) adjunctns, 0. ( Peristedion ) personatus, and 
0. (? Agonus) primus (E. Koken, loc. cit. vol. xliii. 1891, pp. 130- 
1-32, pi. x. figs. 6, 9 ; also loc. cit. vol. xxxvi. 1884, p. 555, pi. xii. 
figs. 9, 10). 
The following extinct genera and species, not represented in tho 
Collection, have been compared with Trigliduc, but are too imper- 
fectly known for systematic determination : — 
Podopteryx alhyi, H. E. Sauvage, Ann. Sci. Geol. vol. xi. (1880), 
art. no. 3, p. 17, figs. 5, 6.— Upper Miocene; Licata, 
Sicily. [The type species. Imperfect fish.]

No extinct members of the aberrant family of Cycloptkhidje are 
known, but remains of the existing Cyclopterus lumpus, Linn., 
have been found in nodules in Glacial Clay in Green s Creek, 
Ottawa, Canada (J. W. Dawson, Canad. Nat. n. s. vol. vi. 1872, 
p. 403).
