GAZZA DISPAR (De Vis). 
Equula dispar De Vis, Proc. Liim. Soe. N. S. Wales ix., 3, Nov. 29, 1884, p. 542. Cape York, Queens- 
land. Holotype (No. I. 13/1701) in Queensland Museum examined. Id. Saville-Kent, 
Prelim. Kept. Food-Fish. Qld., 1889, }). 10, and Ct. Barrier Reef, 1893, p. 369 (listed only). 
Leiogruitlms dispar McCulloch & AVhitley, Mem. Qld. Mus. viii., 1925, p. 145. Id. McCulloch, Austr. 
Mus. Mem. v., 1929, p. 212 (listed only). 
D. viii. ?/17 : A. iii./14 ; P. 18 ; V. i./5 ; C. 16. Head (8-5 ram.) 3, depth (10) 
2*6 in length to hypural joint (26) ; eye (3*1) 2*7, interorbital (2.5) 3*4, snout (2*1) 
4 in head ; second anal spine (4) 2*1 in head ; dorsal s]hnes damaged in type. 
The type-specimen of Eqmila dispar is a small specimen, 33 mm. in total 
length. The spinous dorsal fin, jaws, and opercles are damaged, so that accurate 
description is difficult and figuring impracticable. 
Head deep, the upper profile much less steep than the lower ; interorbital 
with a median ridge, separate from the supraoccipital ridge and flanked on each side 
by two smooth supraorbital ridges ; two antorbital spines ; eye large, circular, not 
so deep as cheek below it ; lower preopercular margin irregularly serrated ; maxillary 
reaching to below anterior fourth of eye ; jaws armed with a single series of strong, 
rather close-set, slightly curved teeth which are of fairly even height except near the 
sympliysis, where larger teeth occur ; gill-rakers elongate, pointed, the longest about 
] mm. ; thirteen on lower limb of first gill-arch. 
Body compressed, deepest anteriorly, the lower profile more convex than the 
upper. The type is now almost denuded of scales. The lateral line follows the curve 
of the back but is now indistinguishable from below the soft dorsal fin. De Vis, 
however, remarked that it \vas/‘ continued to the caudal peduncle.” 
A procumbent dorsal and anal spine ; some raised serrations on the anterior 
surfaces of the bases of some of the erect dorsal and anal spines ; a small axillary 
ventral scale ; a slight ridge extending from below pectoral base to near ventral 
fin ; caudal bilobed. 
Colour no-w faded to stra-w-yellowish with spaced brown punctulations on 
lower parts of head and sides and along base of soft dorsal fin. De Vis described the 
colours as “ silvery-brown on the back with a series of blotches below the base of the 
dorsals.” 
Described from the holotype of Equula dispar De Vis, a specimen 26 mm. in 
standard length or about inches long. Queensland Museum Reg. No. I. 13/1701. 
Thin species is perhaps merely based on a young specimen of Gazza tapetnosoma 
Bleeker, but as the latter was originally described from Batavia, I hesitate to relegate 
the Queensland form to its synonymy without critical com])arison of specimens. 
Gazza dispar has a more attenuate form than the so-called G. equula/formis Ruppell 
from Queensland, and seems to iiave fewer teeth than the extralimital G. arge 7 ifaria 
(Bloch & Schneider).
