AUSTKALIAX GOBIIl)^ McCULLOCU AND OGILBY. 283 



Proportions of a specimen 112 mm. long, from Bnudaberg, Queens- 

 land, figured by Waite (Lor. cit.). Depth at veutrals 3-9 in the length 

 between the premaxillary symphysis and the hypural joint ; head 31 in 

 the same. Eye 56 in the head, shorter than the snout, which is 4"6 in 

 the head ; iuterocular space twice as wide as the eye, 2'8 in the head. 

 Breadth between the bases of the pectorals 1-3 in the depth ; depth of 

 caudal peduncle 2-1 in the head. Sixth dorsal spine 31, last dorsal ray 

 1*4, last anal ray 1'6 in the head. Pectoral 14, caudal 11 in the head. 



This specimen agrees with the foregoing description of M. moyaruda 

 in all details, except in having the dorsal spines somewhat shorter, and 

 the rays of the pectoral and ventral fins longer, which are merely 

 individual peculiarities. 



The subspecies M. in. mUper^n^ differs from the typical form only in 

 having larger and less numerous scales, there being 30-35 in a longitudinal 

 series instead of 38-42, and 13-14 in a ti-ansverse row instead of 15-16 ; 

 the two are similar in all other details. But we have examined several 

 specimens from Powell's Creek and the Palmer River, Central Australia, 

 and inland from Cairns, Queensland, in which the scales number 35-36 

 in a longitudinal series, and 14-16 transversely. These localities are 

 somewhat intermediate between the ranges of the two subspecies, so we 

 are led to the conclusion that the larger and smaller scaled forms are 

 merely geographical races of the one species. 



Synoriyuiy. — Five cotypes of Eleotris mimnit, De Vis, preserved in the 

 Australian Museum, prove this species to be synonymous with M. iii. 

 adupergns, as has already been determined by Ogilby. The holotype of 

 Eleotris concolor, De Vis, is in the collection of the Queensland Museum ; 

 it is stuffed and its tins are much damaged, while it retains no traces of 

 its colour-marking ; its i-emaining characters, however, leave no doubt as 

 to its identity with M. ni. (ulspersus. 



Lacs. — We haA'e examined a i-epreseutative series of S6 specimens 

 from the following localities. South Australia : — Torrens River ; Onka- 

 pariuga ; Murray Bridge. New South Wales : — near Mudgee and Dubbo ; 

 Clarence River. Queensland : — Brisbane River (cotypes of E. iiiinius, De 

 Vis.) ; Eidsvold, Burnett River ; Bundaberg ; 25 miles inland from 

 Cairns.
