disk; posterior dorsal and anal fins equal and opposite, more 
extended than the anterior spinous dorsal. 
Small fishes almost universally distributed on the coasts of 
temperate and tropical seas, sometimes occurring also in freshwater. 
There appear to be no fossil remains in the Collection referable to 
this family, and very little evidence of extinct species has been 
discovered. Imperfect fossils have been described as follows :— 
Callionymus macj'ocephahis, D. G. Kramberger, Beitr. Pal^nt. 
Oesterr.-Ungarns, vol. ii. (1882), p. 134, pi. xxv. fig. 3.— 
Upper Miocene; Badoboj, Croatia. [Imperfect fish 
exhibiting the characteristic branched preopercular spine of 
the existing Callionymus University Geological Museum, 
Agram.] 
OtolitJius (Gohiida'rum) dispar, E. Koken, Zeitschr. deutsch. geol. 
Ges. vol. xliii. (1891), p. 133, pi. x. fig. 12.—Miocene; 
Erankfurt. [Otolith.] 
. . Otolithus (Gohius) francofurtanus, ^dken, ihid. 132, pi. vi, 
, fig. 7.—Lower Miocene ; Erankfurt, Eckenheim, Ginheim, 
^' and Bornheim. Middle Miocene ; Portsteich. [Otolith.] 
Otolithus (Gobius) vicinalis, E. Koken, ibid. p. 133, fig. 21.— 
Miocene; Unterfeld and Oberfeld. [Otolith.] /y7<o^rne: 
merely names for undetermined fishes from the Upper Miocene of 
Gabbro, Tuscany (de Bosniaski, Atti Soc. Tosc. Sci. Kat.—Proc.- 
Yerb. vol. i. 1878-79, pp. xix, Iv). ^ 
The so-QSiU3d Gobius leptosou/^uhT^a macroactus (D. G. Kram¬ 
berger, Palaeontogr. vol. xxvi. 1879, pp. 63-65, pi. xvi. figs. 4, 5), 
from the Lower Oligocene of Galicia, are too imperfectly known 
I for certain reference to this systematic position. The same remark 
applies to Gobius microcephalus, which was only doubtfully placed 
here by Agassiz (Poiss. Loss. vol. iv. 1839, p. 204, pi. xxxiv. fig. 2), 
and is probably a Blennioid though not satisfactorily determinable. 
The last species is represented in the Collection by the following 
specimen:— 
44873. Typical specimen of the so-called Gobius mierocephalus, 
Agassiz, in counterpart; Upper Eocene, Monte Bolca, 
near Verona. The dorsal fin is continuous, with about 
18 rays. The pelvic fins are rather large.
