NEW OR INSUFFICIENTLY DESCRIBED FISHES. 49 
black spot between the fourth and seventh rays ; anal with a similar 
but much smaller spot between the fourth and fifth rays ; caudal 
and pectorals uniform light brown ; ventrals much darker. 
Described from a single specimen, 80 millim. long, forwarded 
from Dunk Island to the A.F.A.Q. Museum, by Mr. E. J. Banfield, 
Cat. No. 1515. 
This species differs from every other Queensland Amia, except 
A. nigripes (q.v.), in the presence of a complete nuchal shield which 
entirely excludes any predorsal scales. 
I have much pleasure in naming this beautiful species after 
Mrs. Bertha Hamlyn, the wife of Dr. Hamlyn-Harris, Director 
of the Queensland Museum, who has kindly permitted me so to 
designate it.

D. vii, i 9 ; A. ii 8 ; P. 15 : Sc. 2/23/6. Depth of body 2, 
length of head 25, of caudal fin 4, of pectoral 4, of ventral 3 in 
length of body. Depth of caudal peduncle 2*4, length of snout 39, 
diameter of eye 3'4, width of interorbit 3'65, length of maxillary 
1*75, longest dorsal spine 2, longest ray 1*7, second anal spine 3'3, 
longest ray 2 1 in length of head. 
Body short and stout, the ventral contour more arched than the 
dorsal, its depth one fifth more than the length of the head. Upper 
profile of head and nape linear throughout ; length of snout 1*15 in 
the diameter of the eye, which is slightly more than the feebly 
convex interorbital width. Lower jaw projecting ; maxillary extend- 
ing to below the middle of the orbit, the width of its distal extremity 
2 in the eye-diameter. Outer edge of preopercle feebly denticulated 
throughout its entire length. Scales adherent ; nape scaleless ; 2 
interdorsal scales. 
First dorsal fin well developed, the spines strong ; second rather 
less than half the third, which is the longest, 1*15 in the second and 
third rays. Caudal rounded. Anal originating below the second 
dorsal ray. Pectoral short, not extending to above the vent. 
Middle ventral ray longest, reaching to the anal rays, and 1*33 time 
the length of the pectoral, its spine 1*3 in that of the spinous dorsal
