172 MEMOIRS OF THE QUEENSLAND MUSEUM. 



iit Hervey Bay, where five were taken in one haul on black sand at a depth of 

 14 to 16 fathoms. Though so far only recorded from the shores of South 

 Queensland it has all the appearance of a northern fish, and I would not be 

 astonished if it should prove to be common further up our coast. This view is 

 also supported by the fact that all the examples which I have handled were of 

 about the same size and, with the exception of the Hervey Bay haul, were taken 

 singly and at long intervals, thus suggesting that they were wanderers. 



Uses: — These are excellent fishes for the table, comparing favorably with 

 even the best of our breams. 



Dimensions: — Apparently the specimens examined have reached the full 

 .size to which the species attains. 



Illustration: — Miss Clark's beautiful figure was taken from the type, 

 the larger of the two described examples. 



Part IX.— TEUTHIDOIDEA (No. 1). 

 Suborder TEUTHIDOIDEA. 



Teuthkloidea Gill, Troc. U. S. Nat. Mus., vii, 1884, p. 276 . 



The suborder may be defined as follows: — 



"Percomorphous teleosts with ovate or subovate bod}', covered with 

 minute adherent scales; lateral line complete, not extending on the caudal fin. 

 Mouth terminal and but little protractile, with narrow horizontal cleft. Vomer 

 and palatines toothless. Nostrils double. Eyes lateral and high-placed. One 

 dorsal fin; ventrals thoracic and approximate, the inner ray attached by 

 membrane to the wall of the abdomen. Gill-openings moderate ; gill-membranes 

 broadly attached to the isthmus; branchiostegals 5 or (in Monoceros) 4; pseudo- 

 branchia- well dt^veloped ; gills 4, a slit behind the fourth ; gill-rakers vestigial. 

 Air-bladder present. Intestinal canal with many convolutions; pyloric 

 appendages in small number. Premaxillary and maxillary bones firmly united; 

 entopterygoid present ; posttemporals co-ossified with the cranium. Interneurals 

 with transversely expanded buckler-like subcutaneous plates, which intervene 

 between the spines and limit their motion forwards." 



Herbivorous fishes of moderate size from nearly all w^arm seas, but 

 chiefly abounding within the tropics. They are said to be of excellent quality 

 for the table but, like all weed-eating species, they do not keep well unless 

 they are cleaned as soon after capture as is possible ; otherwise the flesh is 

 •sure to deteriorate rapidly, and become unfit for food.
