PISCES.

Cataphracti. 
'i Affonus decagonm. A single example has been found in the WarangerQord 
(N. Scandinavia). Malmgren in Wiegm. Arch. 1864, p. 280. 
Discoboli. 
Liparis. The species of this genus are but imperfectly known, and there 
are considerable discrepancies in the descriptions given by various authors of 
species which they have designated by the same name. Mr. Gill has collected 
and examined what has been published of the species occurring on the Atlantic 
coasts of North America, and enumerates five species, one of which, although 
most closely allied to L.fahridi^ is described as distinct — L. arctica, Proc. Acad. 
Nat. Sc. Philad. 1864, p. 191. 
Two Finnish species are distinguished by Hr. Malmgren (Wiegm. Arch. 
1864, p. 287) -^Liparts harhativs (Ekstr.) and Uneaius (Lepechin), the t 
former from the Glacial Ocean and Baltic, the latter from the White Sea only. 
Gobiid^. 
Gohius melanostoma (Pall.), G. Jluviatilis (Pall.), and G. gymnotrachelus 
(Kessl.) are redescribed by Prof. Kner, who received specimens from the 
I)nj ester and Pruth. He considers G. lactem (Nordm.) distinct from 
G.Jliiviatilis. Verb. Zool.-Bot. Ges. Wien, 1864, p. 76. 
^ Gohius punctatissirnm^ sp. n., Canestr. Arch, per la Zool. 1864, p. 101, from 
fresh waters of Northern Italy. 
Cotylopiis, g. n., Guichenot, in Maillard, Notes sur Tile de la Reunion, App. 
p. 9. Similar to Sicydinm, with a series of minute flexible teeth in the upper 
jaw, dilated and deeply notched at the tip j lower jaw with a single series of 
strong conical teeth *, without horizontal labial teeth. Body with scales of 
moderate size. C. acutipinnis (p. 10) and C. parvipinnis (p. 11), both from 
Bourbon. 
Gillichtliys^. Dr. Cooper has discovered a most interesting genus of Gobioid 
fish, which has the upper jaw produced backwards to the gill-opening, re- 
minding us of Opisthognathus and Neoclinus. The gape of the mouth reaches 
only to below the hind margin of the eye. Ventrals united into a funnel- 
shaped disk ; two separate dorsals. Villiform teeth in the jaws, none on the 
palate. Scales small and thin; lateral line none. G. mirahilisj fig. 24: 
D. 6 1 13. A. 11. Proc. Calif. Acad. Nat. Sc. iii. p. 109. 
Eleotris seminudus, sp. n., Gunther, Proc. Zool. Soc. 1864, p. 24, pi. 4. fig. 2, 
from the Pacific Coast of Panama longiceps, sp. n., Gunther, ibid, 
p. 151, from the Lake of Nicaragua ; Eleotris coxii, E. australis^ and E, gran- 
dicepSj.'Kxe^t, ibid. p. 183, all from New South Wales; Eleotris conipressuSf 
KiefFt, ibid. p. 184, from the Clarence -River. 
/ Amhlyopus hrevis, sp. n., Giinther-, Proc. Zool. Soc. 1864, p. 161, from the 
Pacific coast of Panama. 
* We suppose that, by a slip of the pen, M.. Guichenot wrote Cotylopes 
instead of Sicydium in the ninth line of his description ; otherwise the diag- 
nosis would be quite incomprehensible. 
t We hope Dr. Cooper will not continue to use this barbarous name, which 
is not worthy either of the author or of the man whom lie intended to honour 
by it, but substitute for it a form more in accordance with the rules of no- 
menclature, like Gillia.
