like 8. maculata, but wants the silvery lateral stripe, and shows spots 
on the dorsals; D. 10. 20; A. 1. 21. 
McClelland establishes a new Percoid genus allied to Sillago, from a 
very small Fish which Buchanan has figured and described as an Atherina. 
He calls it Cestrwus, which name had already been used by Cuvier and 
Valenciennes. Its characters are, head oval and flat anteriorly ; eyes 
projecting and forward; jaw flat and turned upwards; small conical 
teeth on the intermaxillary ; four gill rays and two rough ledges, those 
at the upper and posterior angle of the operculum end in blunt points ; 
pectorals round, over the ventrals, the first ray of which is a prickle ; 
dorsals far separate ; a fleshy projection from the anal fin. 0. minimus ; 
D. 5-9 ; P. 16 ; V. 1. 5 ; A. 12 ; C. 13. (Calcutta Journ. ii. 1842, p. 151.) 
Ranzani, 1. c. v. p. 340, arranges a new genus, Diapterus, in the 
family of the Percoids. The species described, however (D. auratus), 
does not seem to me different from Gerres hrasilianus, Cuv. and Val. ; 
and must return to that genus. 
Scorpoena hurra, Richardson, Ann. ix. p. 215 ; crimson fading to 
reddish-white on the branchiostegous membrane ; the side of the head is 
veined with deeper lines ; all the cirrhi are green, and the body is marked 
with a few irregular olive green blotches. 8c. panda, id. ib. p. 216 ; 
scales very large, thirty-five in a row, and about sixteen in a vertical 
line ; vermillion with two dark hyacinth-red bands on the side ; body 
spotted with round drops of dark orange-brown ; D. 11-10 ; A. 3-6 ; P. 
16. 8c. ergastulorum, id. ib. p. 217 ; scarlet ; a black spot crosses the 
ninth, tenth, and eleventh dorsal spines ; P. 15 ; D. 12-9 ; A. 3-5. 8c. 
militaris, id. Transact. Zool. Soc. iii. p. 90 ; capite breviusculo, cirrhis 
nullis (?), spinis capitis fere Scorpcense porci vel bufonis, operculo summo 
genisque squamosis, squamis coporis ciliatis ; colore carmesino ; B. 7 ; 
P. 16; D. 12. 10; A. 3. 5; V. 1. 5 : AustraHa. 
8ynanceia trachynis, Richardson, Ann. ix. p. 385, allied to the 
8c. horrida and hrachio, but the posterior dorsal spines are lower than 
the anterior ones ; the prseoperculum has a spine ; and the species has 
vomerine teeth. (It belongs, therefore, to the genus 8ynancidium. J. 
Miill. Abh. d. Acad, zu Berlin, v. j. 1839.) 
Ranzani, 1. c. v. p. 342, distinguishes the genus HcBmulon into two 
divisions. The first contains the longish, not much compressed species, 
with complicated lateral lines ; the second, those with high compressed 
body and simple lateral lines. In the second division, two new species 
have been described, II . mdanopterum, P. 17 ; D. 12. 18; A. 3. 9; and 
II. moricandi, P. 17 ; H. 12. 16 ; A. 3. 9 : both are from Brazil. 
Scolopsis longulus, Richardson, Ann. ix. p. 389 ; four times as long it 
is high; D. 10-9; A. 3-7; P. 17. 
Amphiprion melanostolus, Richardson, Ann. ix. p. 390 ; three white 
vertical bands ; head and body black ; pectoral fin black at the base, the
