 dark longitudinal lines characteristic of var. manillensis. Length 10 inches. 



369b. T. hispidus. Id. Linne. Syst. Nat. 10th. ed., 1758, p. 333. Crayra- 



cion laterna Bleeker. Atlas Ichth. v., 1865. p. 71, pi. 205. 3. 

 A tropical species, which is not reliably recorded from New South Wales.

369c. T. aerostaticus. Balloon-fish. Id. Jenyns. Zool. Beagle iii.. 1842, 

 p. 152. Crayracion lineatus Bleeker. Atlas Ichth. v.. 1865, p. 70, pi. 

 212, 1. T. amabilis Castlenau. P.L.S. N.S.W. iii., 1879, p. 401. 



A tropical species, of which young specimens occasionally stray southward 

 to Port Jackson. T. amabilis Castlenau, was described from a specimen 4J inches 

 long from Port Jackson in 1879, since which time the species has not been re- 

 cognised. A local example of similar size is in the Australian Museum which, 

 while agreeing well with Bleekers figure quoted above, presents sufficient of the 

 characters described by Castlenau as to leave little doubt that amabilis is synony- 

 mous with aerostaticus.
