IN THE QUEENSLAND MUSEUM, 
triangular ; hinder limb of preopercle linear and nearly vertical, 
finely serrated as also is the oblique lower limb ; preopercular spine 
short, reaching but little beyond the border of the subopercle, with 
a strong double median ridge, 2-t in the diameter of the eye ; a 
pair of strong opercular spines, with one or two denticles above 
them. Upper surface of head with a pair of median ridges, 
enclosing a concave porous area ; supraciliary ridges smooth in 
front, and with two strong and several small spines behind ; parietal 
region with about nine flabelliform ridges, temporal with one 
somewhat coarser ridge, all smooth but terminating in acute spines; 
articular bones with coarse somewhat anastomosing smooth strife. 
Dorsal fin originating behind the opercle, the 1st. spine f of the 
3rd., which is the longest, \ of the length of the head and T % of the 
2nd. and 3rd. rays, which are equal and longest; last spine but 
little longer than the 10th., 3f in the longest spine. Anal origi- 
nating below the 4th. dorsal ray ; 4th. spine stronger and nearly as 
long as the 3rd. dorsal spine, If in the 3rd. spine, which is 3f in the 
length of the body ; 2nd. ray longest, scarcely so long as the 
longest dorsal ray. Middle caudal rays 2\ in the upper lobe, 
which is 4f in the body : least depth of peduncle If in the diameter 
of the eye. Pectoral fin extending to below the 7th. dorsal spine, 
If- in the length of the head. Ventral a little shorter than the 
pectoral, but reaching considerably further back, to midway between 
its origin and the base of the 3rd. anal ray. Gill-rakers 1 + 6, with 
some tubercles on both branches, the longest 4i in the diameter of 
the eye. Colors after long immersion in alcohol and exposure to 
the light — yellowish silvery, with traces of about eight darker 
longitudinal bands ; each of the scales of the back above the lateral 
line with a chestnut basal spot, which diminishes in size posteriorly 
until beyond the spinous dorsal it is broken up into numerous fine 
dots : upper surface of head brown ; scales of cheek similar to 
those of the back : fins immaculate, [anc/ustzcs, narrow ; frons, 
forehead, i.e. interorbital region]. 
Described from a specimen measuring 153 millimeters, pre- 
sented to the State Museum by Capt. C. P. Browne, who obtained 
it at New Britain. 
The species belongs to the sammara -Iceve group, but may easily 
be distinguished from either of those species by the narrow inter- 
orbital region, which in both of them measures f of the eye as 
against only f- in this species. The number of longitudinal series 
of scales is also greater, of pectoral rays fewer, the premaxillary 
groove is shorter, the preopercular spine is strongly ridged and 
extends beyond the subopercular border, etc.
