PISCES.

the synonymy of the species of the East-Indian Archipelago, 
adding the names of other localities whence the species are said 
to have been obtained (Nederl. Tydschr. Dierk. iii. 1865, 
pp. 20-40) . For the details we must, of course, refer to the 
paper itself. 
Dr. Bleeker has given an account of the species occurring 
in the East-Indian Archipelago (Atl. Ichthyol. v.) . He describes 
and figures thirteen species of Ostracion (pp. 25-42, pis. 201- 
204). The Tetrodontes (pp. 45-83, pis. 205-215) are arranged 
thus * : — 
I. Diodontiformes. 
Phalanx A. Trirhizacanthmi, with the genera Chylomycterus (Bibr.) 
— Dicotylichtliys (Kaup) ; Diodon (L.)= CycUcthys^ CyanicMhysj and Chylo- 
mycterm (Kaup). 
I’halanx B. Dirhizacanthwi, with the genera Atojiomyctcrus (Verr.) ; 
Varadiodon (Blkr.)= JD/odon (Kaup) j TricJiodiodon (Blkr,, type D. pUosuSy 
Mitch.). 
II. Tetraodontiformes. 
Phalanx A. Tetraodontinij with the genera Tetraodon (h.)—rhyso-‘ 
gaster, Gastrophysm et Cheilichthys (Miill.), &c. ; Crayracion (Klein) = 
thron (Miill.), &c. ; Ldodon (Swains.) = (Miill.), &c. ,* Chme- 
rhinus (JSXkr.^ — Xejiopterus (Bibr.) j Ephippion (Bihr.). 
Phalanx B. CantJiogastrinij with the genus CantJiogastcr (Swains.) 
= Psilonotus (Swains.) = Anosmius (Ptrs.) — Tt'opidichthys (Blkr.) = Rhyn- 
chotus (Bibr.). 
Of Triodon one species is described (p. 84, pi. ^14. fig. 1), 
of Triacanthus six (pp. 88-92), one of which is new, Tricnnthus 
macrurus (p. 91, pi. 232. fig. 3, or Nederl. Tydschr. Dierk. iii. 
1865, p. 51), from Java and New Guinea. 
Ostracion. Dr. Bleeker (Nederl. Tydschr. Dierk. ii. 1865, pp. 298-305) 
shows that several species have been confounded under the names of 
^ 0. quadricornis (L.) and ©. tricornis (L.) : not only are these two distinct 
species, the latter being identical with'*'0. maculatm (Holl.), but also three 
others may be distinguished, viz. O. gronovii (Blkr.)= 0. quadricornis (Bl.), 
O. guineensis (Blkr.) = 0. quadricornis (Blkr. M^m. Poiss. Guin. p. 20), and 
O. notacantlius (Blkr.). The last is figured. 
'4 \^Arothron'\ Crayracion cochinensis, sp. n,, Day, Proc. Zool. Soc. 1865, 
p. 314, or Fish. Malabar, p. 258, pi. 20. fig. 1, from Cochin. 
4 [^Chdcmodoti] Leiodon viridipunctatus^ sp. n., Day, Proc. Zool. Soc. 1865, 
p. 315, or Fish. Malabar, p. 258, pi. 20. fig. 2, from Cochin. 
* We have to mention that Dr. Bleeker has published, as a preliminary to 
the appearance of the ‘ Atlas Ichthyologique,’ the whole of the system of 
Plectognaths, in Nederl. Tydschr. Dierk. iii. 1866, pp. 8-19.
