NOTES ON FISHES FROM WESTERN AUSTRALIA — WAITE. 191 



In our examples of S. hassensis the fin formula is D. xi., i, 21 ; 

 A. ii., 18 ; Lateral line 69. In the original description of the 

 species the figures have been transposed in some way, so that they 

 cannot be considered. The following proportions may be compared 

 with those rendered by Ogilby" of S. maculata : — 



Length of head 3'4, of caudal fin 6"3, height of body 4-7 in the 

 total length. Diameter of eye 5-0 in the length of the head and 

 2 3 in that of the snout. Opercle with one sharp point. Ventral 

 not filamentous 1-6 in the distance between its origin and the vent 

 and half the length of the head. 



The colours also supply distinguishing features : — in S. maculata 

 the back is sandy-brown, and the sides have seven or eight dark 

 blotches (said to be sometimes absent) a dark spot always present 

 at the base of the pectoral. In S. bassensis the back is reddish- 

 brown, there are no dark blotches on the body and no dark spot 

 at the base of the pectoral. 



In the work quoted, Ogilby states that " S. bassensis, if a good 

 species, inhabits Tasmanian waters only." Western Port, the 

 locality of the type specimen is in Victoria ; the examples now 

 received are from Mandurah and the Abrolhos. 



In his generic description of Sillago, Day^^ writes: — "Lateral- 

 line not continued on to the caudal fin." I have no Indian species 

 by me for the verification of this: it is not true of Australian 

 species, however, though Ogilby in copying Day's paragraph has 

 overlooked it. It is doubtless a misprint in the original, as in 

 our examples of S. maculata, which Day includes, the lateral line 

 is continued quite to the end of the caudal; McCoy has noticed 

 this in aS. ciliata}^ 



Sillago maculata, Quoy and Gaimard.

 pi. liii., fig. 2. 



Having a wide range this species has been recorded from eastern 

 and (?) northern Australia, and has been seen but once in Victoria. 

 It is possibly common on the western coasts, we have examples 

 from Fremantle.
