PISCES.

horridus j Fish. Malabar, p. 4, pi. 1, where both fishes are figured. Such a 
change of colours is quite possible, but Mr. Day has omitted to notice the re- 
markable difference in the length of the dorsal spines, so conspicuous in the 
figures given. We may add that already Mr. Blyth has expressed it as his 
opinion that this fish represents the young state only of another Serranus^ 
which, however, he has identified with S. coioides or suillus (Journ. As. Soc. 
Beng. xxix. p. 111). 
Tlectropoma. Prof. Peters (Monatsber. Ak. Wiss. Berl. 1865, p. 105) has 
recogiiized the identity oi'^Alphestes afer (Bl. Bpinephelus afei' (Bl.) 
yvit\r Plectropoma chloropterum (Val,) = P. monacanthus (Miill. & Trosch.). 
He demurs to the generic separation of Plectrcpoma from Sei'ranus, and says 
that, at all events, the name Alpliestes would have the priority before P/ec- 
tropoma, 
Diploprion hifasciatum. Prof. Kner has found nine pyloric appendages. 
Novara, Fisch. p. 29. 
Myriodoyi waigiensis described by Kner, 1. c. p. 38. 
Mesoprion. Prof. Kner describes the following species : — a. with the tongue 
smooth : iff. annularis^ 1. c. p. 33 ; M. enneacantlmSy p. 34 ; M. decussatus, 
p. 34. /8. with the tongue toothed : M. chrysotamia^ p. 34 ; M. rcntguSy 
p. 34 ; M. johnii, p. 35 ; M. fulvifiamma, p. 35 ; M. lineolatus, p. 36 ; M, vittUy 
p. 37 ; M. lutjanus, p. 37. 
Mesoprion aurolineatus, fig. by Day, Fish. Malabar, pi. 3 ; M. sillaoo, ibid, 
pi. 2. fig. 1 ; M. rubellus, pi. 2. fig. 2. 
Mesoprion alhostriafus (Bl. Schn.). On its synonymy see Peters, Monatsber. 
Ak. Wiss. Berl. 1865, p. 111. 
Genyoroge. Prof. Kner unites this genus with Mesoprion, and regards also 
the character of a smooth or toothed tongue as not being of generic value 
(Novara, Fisch.). lie describes G. sehee (p. 30), G, heyigalensis (p. 31), G. 
marginata (p. 31), G. hottonensis (p. 32, taf. 2. fig. 3). All these species have 
a smooth tongue. 
Priacanthus macrophthalmus. Some remarks on this species by Kner, 
1. c. p. 39. 
Ambassis commersonii and A. dussumieri are described by Kner, 1. c. p. 41. 
Apogon. Prof. Kner has made remarks on A. hyalosoma, A. bifasciatus, A. 
quadrifasciatus, and A. fasciatus. L, c. pp. 42 & 43. 
Ampis. Prof. M^Coy states that he has satisfied himself, from 
an examination of a great number of fresh specimens, that Cen- 
tropristes georgianus (Cuv.), C. solar (Richards.), C. truttaceus 
(Cuv.), Perea trutta (Cuv.), and probably Perea marginata (Cuv.) 
are the same species, and that this species, called Salmon or - 
Salmon Trout in Melbourne, has about 160 pyloric appendages, 
and from 16 to 19 soft dorsal rays. Ann. & Mag. Nat. Hist. 
1865, xvi. p. 187. 
The Recorder cannot agree with this opinion. Valenciennes* 
describes in such a manner the 17 pyloric appendages of 0. 
* Prof. M^Coy attributes this statement to Gunther, but he might have 
obseiwed that skins only are in the British Museum of this species, and that 
that statement is taken from Valenciennes’s original account.
