Description of the lectotype of Dcjiiula decora De Vis. 
D. viii. /IT) ; A. iii./14 ; P. 21 ; V. i,/5 ; C. Jb. L. lat. 50 + ? Head (10 mm.) 
2*9, and depth (14) 2*07 iu length to hypural joint (29) ; eye (S-6) rather greater 
than postorbital portion of head (3*3) and interorbital (3-1) which is equal to snout (3*1). 
As the types are young specimens and the heads slightly shrunken in preservation, 
it is probable that the eye would normally be subequal to these other dimensions in 
this species. Second dorsal s])iue (5*5) 1*8, and second anal spine (5) 2 in the head, 
and shorter than the ])cctoraI fin (0). 
Agrees in general details with my description of the holoty])e of Equula argentea 
De Vis = Leiognaihus devisi Whitley, published in 1929, and agrees exactly when the 
type-specimens ai’c compared. 
Sup)ra jrbital ridge very sliglitly rugose posteriorly ; inner antorbital spines 
largest ; gill-rakers slender, pointed, pectinate ; a bony peg protrudes into the 
branchial aperture before the pectoral base : the scales are now rubbed off the types 
of Eqmda demra and it is impossible to obstTve whether the breast was naked or 
scaly ; lateral line complete, continuous to caudal, but the tubes are small on the caudal 
23eduucle ; no trace of a black dorsal blotch ; second to fourth dorsal, and second 
and third anal s]>ines with strong serrations anteriorly along the jjroximal halves ; 
these serrations are less conspicuous iu tlic type of Leiognaihus devisi j upper caudal 
lobe longer than head without snout.
