30 MEMOIRS OF TEE QUEENSLAND MUSEUM. 
This novelty is closely allied to the eastern Australian form but differs as- 
follows : — • 
No spines over orbit. Groove for nostrils more excavated. Junction of 
scutes not so straight and even as in T. reipublicce but each scute margined 
with close-set grooves at right angles to its edge, which is correspondingly 
notched. Rugosities not so pronounced, more in the form of rounded, 
reticulating irregularities of surface. Lateral scutes immediately before the 
caudal peduncle forming a sculptured shelf which is more evident in T. pyxis 
than in T. reipublicce , to which it is similar, though scarcely identical, in other 
details. Five scutes on dorsal ridge. Nine dorsal and anal rays. 
Holotype [I A. 394 ) and paratype {I A. 39-5) in Australian Museum, from 
Cottesloe, near Perth, Western Australia. 
Genus ACANTHOSTR ACTON Sleeker, 1866. 
Acanthostraeion pentacanthus (Bleeker). 
Ostracion pentacanthus Bleeker, Act. Soc. Sci. Ind. Neerl. ii, 1857, p. 98. Amboina. 
Ostraeion (Acanthostraeion) fornasini Bleeker, Atlas Ichth. v, 1865, p. 34, pi. cciii, fig. 4. Amboiua, 
Not O. fornacini Bianconi from Mozambique. 
One specimen (Qld. Mus. 1. 1375) from Southport, South Queensland ; 
presented by V. J. Hargraves. Length of carapace 84 mm. New record for 
Australia. This tropical species has been recorded from New Zealand as 
Ostracion fornasini, but it is doubtful whether it occurs so far south. 
The species called Ostracion (Acanthostraeion) fornasini in Bleeker s Atlas 
Ichthyologique is probably not 0. fornasini Bianconi 92 from Mozambique, but 
is O. pentacanthus Bleeker from Amboina. Bianconi’s original description is not- 
available in Australia, but Barnard 9,5 states that Lactoria fuscomaculata von 
Bonde is a synonym. Von Bonde’s illustration 94 shows a species with thicker 
mouth region, more depressed dorsal spine, less branched caudal rays, and 
smaller anal spines than Bleeker’s figure represents. The Queensland Museum 
specimen, compared with von Bonde’s figure, differs in having the head a little 
over 3 in length of carapace, scutes of chin, breast, and posterior part of sides 
particularly rugose, no dark band from eye to pectoral, and markings on body 
tending to form wavy lines. 
Gunther 90 figured an allied form with much stronger preorbital and anal 
spines than the Indo-Australian species possesses. Ftis figure apparently 
represents a distinct Hawaiian species, named Lactoria gal-eodon by Jenkins. 96
