ZOOLOGICAL LITERATURE. 
georgianm, tliat we can hardly doubt the correctness of this 
number ; and as this species has 14 soft dorsal rays only. Prof. 
M^Coy must have examined a different species. For the same 
reason, the Recorder does not think that the fish examined by 
Prof. M^Coy is O. solar, which has only 50 pyloric appendages. 
Therefore it remains to be seen whether the Melbourne Salmon^^ 
is the Centropristis truttacea, Cuv. & Val., or whether it is a 
distinct species altogether, which, like its congeners, is subject 
to certain changes dependent on age. But the Recorder fully 
agrees with Prof. M^Coy that the Perea marginal a of Cuvier 
also belongs to this genus, and that it is probably merely a no- 
minal species. 
Centrarchus. For species with six dorsal spines the name Pomoxys is 
adopted by Mr. Gill. ^ He is acquaii^ed with four specie^ three of which are 
described as new, viz. P. hrevicauda, P. intermedius, and*^. p?'otacanthus j for 
the fourth (P. nitidns, Girard) the name P. storerius is adopted. Proc. Ac. 
Nat. Sc. 1865, pp. 64-66.

Oilontonectes (Gthr.) is reunited with Ctssio by Kner, Novara, Fisch. p. 63. 
JDides t^niurus. A young- example from Tahiti is described by Kner,

PRISTIPOMATIDiE. 
Tli^’apm. Prof. Knej (Novara, Fisch.) describes: T, trivittatus, p. 45; 
T. quadrilimatus, p. 46 ; '^Datnia plumlea, sp. n., p. 48, taf. 3. fig. 1, from the 
Cape of Good Hope and St. Paul. . The author states the reasons by which 
he is induced to retain Datnia as a distinct genus. 
Helotes sexlineatus has only seven pyloric appendages, according to Kner, 
I c. p, 46; this species is figured, taf. 3. fig. l, from an example from Manilla. 
Pridipoma. Prof. Kner has made remarks on P. nayeh, I, c. p. 61 ; P. linea- 
tum, p. 62 ; and P. yuoraca, p. 63. 
Pristipoma humile (Kner & Steind.), fig. in Abhandl. Bayr. Ak. Wiss. x.

Pristipoma coro. Prof. Troschel thinks it possible that this is a nominal 
species and identical with Conodon plumiari, — in Muller, vVirbelth. Mex. 
p. 91. 
^ Conodon plumieri. Prof Troschel, 1. c., has found distinct pseudobranchise 
in this fish. 
Diyramma affine. Mr. Day’s statement (Fish. Malab. p. 23) that Pristi- 
poma niyrum of Cantor is this species, is correct; but he was not justified, 
without further proof, in identifying it with the fish described by Cuvier and 
Valenciennes.
