MEMOIRS OF THE QUEENSLAND MUSEUM. 
Bombay Duck can be procured in ‘‘ chop suey ” restaurants in Australia, but the 
living fish also occurs in our tropical waters, though, so far as can be discovered at 
present, not as regularly as it does in India. Saville-Kent described it as H. translucens. 
So far, statistical investigations have not been made on the Indian and East Indian 
H. nehercusy which may be found to vary within geographical limits, so I keep Saville- 
Kent’s name for the Australian species, especially as this seems to be smaller and to 
have a different dorsal fin formula. 
HARPADON TRANSLUCENS Saville-Kent. 
(Plate XI. fig. 1). 
Harpodon translucens Saville-Kent, Proc. Roy. Soc. Qld. vi, 5, 1889, pp. 222 and 234, 
pi. xiii, fig. 2. Ord River, Cambridge Gulf, North Australia. Co-types (Nos. I. 2773-4) in Austr. 
Mus., Sydney. Id. Ramsay, Ann. Rept. Austr, Mus. 1890 (1891), p. 20- Id. McCulloch, Austr. 
Mus. Mem. v, 1929, p. 77. 
This species of Bombay Duck has been recorded from North to north-western 
Australia, and must now be added to the Queensland list as Mr. A. Bonding has 
presented a specimen from the Fitzroy River, Rockhampton (Qld. Mus. regd. No. I. 
5565), thereby greatly extending the known range of the genus. This was captured 
on Nov. 22nd in the “ town reach,’’ and forwarded by Mr. W. K. Cleeve to the Queens- 
land Museum. 
I have identified this specimen as Harpodon translucens by comparing it directly 
with Saville-Kent’s types in the AustraUan Museum. The Queensland specimen 
agrees with them, though it is a little larger, 80 mm. in standard length. It has depth 
12 mm., head 17, ventrals 23, eye 2, interorbital 4*5. Fifteen rays in dorsal and anal 
fins. Posterior part of body with weak cycloid scales. General characters of the 
genus. 
Colour in formalin pale milky white, minutely dotted with brown on the upper 
half of the fish. Eye and viscera bluish. Tips of dorsal and caudal fins blackish. 
I have also compared specimens of Harpodon nehereus from China and Madras 
with H. translucens. The scales and lateral line are better developed in these large 
(8-lOJ inch.) specimens and the top of the head near the eyes is more rounded. These 
examples of nehereus have only 12 dorsal rays instead of fourteen or fifteen as in 
H. translucens.
