acknowledged in the Philosophical Transactions of the Royal Society, so that the dates 
of publication are approximately as follows ; — - 
Vols, i, ii, iii, 1800-02 acknowledged Phil. Trans, by February 4, 1802 
VoL iv, 1803 acknowledged Phil. Trans, by December 22, 1803

I have elsewhere tabulated (Austr. Zool. viii, 1936, p. 189) the dates of publica- 
tion of the Nouv. Diet. Hist. Nat. so that the priority oifraenatus is established : » 
Balistes fraenatus Latreille, 7 March 1804. 
Balistes ca/pistratus Shaw, 8 November, 1804. 
The Australian Musetim has specimens of fraenatus from the Great Barrier 
Reef, and Moreton Bay, Queensland, also Lord Howe Island, and Aneiteum, New 
Hebrides. Professor W. J. Dakin collected it at Nauru. 
Family TRIURIDAE (Ranzaniidae, olim.) 
Genus TRIURUS, Lacepede, 1800. 
Triurus Lacepede, Hist. Nat. Poiss. ii, 1800, p. 200. Haplotype, T. hougainvilleanus 
Lacepede. 
Ranzania Nardo, Atti i Riun. Sci. Ital. ed. 2, 1840, p. 165. Orthotype R. typus Nardo (fide 
Sherborn, Index Anim.). 
This grouping and the following synonymy result from my identification of 
Triurus as a young Oblong Sunfish. Lacepede’s genus must not be confused with 
Triurus Swainson, 1839, which is a synonym of Harpadon^ the Bombay Duck dealt 
with earlier in the present paper (p. 119). 
TRIURUS LAEVIS (Pennant). 
Ostracion laevis Pennant, Brit. Zool. iii, 1776, ed. 4., p. 129, pi. xix, fig. 54. Plymouth, 
England. 
Triurus hougainvilleanus Lacepede. Hist. Nat. Poiss. ii, 1800, p. 200. Between 26^ and 
27° S. lat. and near 103° or 104° E. [of Paris] longitude [ = Indian Ocean] ; in stomach of 
mackerel, February 1768 (Commerson). Id. Bose. Nouv. Diet. Hist. Nat. ed, 1, xxii, 1804, p. 408 
and Latreille, ibid, xxiv, 1804, p. 104. Id, Fleming, Edinb. Encycl. (Brewster), Ichth. 1830, p. 693. 
Id. Oliver, Life of Philibert Commerson, 1909, p. 119. 
Triurus cormnersonii Shaw, Gen. Zool. (Pisces) iv, 1, 1803, p. 78. New name for T. hougain- 
villeanus Lacepede. Id, Swain, Proc. Acad. Nat. Sci. Philad. 1882 (1883), p. 303. 
Ranzania laevis Whitley, Rec. Austr. Mus. xix, 1933, p. 108 (further synonyms and refer- 
ences). 
The identity of Triurus has always been a mystery but from Lacepede’s 
description it seems- obvious that it is a young Oblong Sunfish {Ranzania), in which
