17*2 RECORDS OF THE AUSTRALIAN MDSEDM. 



Apogon (/illii, Giintlier, Ann, Mag. Nat. Hist. (4), xvii., 1876, 

 p. 392.

Mionurus glllii, Ogilby, Mem. Qld. Mus., ii, 1913, p. 92. 



A good series of twelve specimens, 42-113 mm. long, is 

 preserved in the Australian Museum from Eidsvold, Queens- 

 land. The variation in the fin-rays and scales of twelve 

 specimens is as follows : — D. vi. i/9-10 ; A. ii/8-9 ; 1. lat. 25-31. 

 The proportions of two specimens 111 and 42 mm. long are 

 respectively. — Depth 2.4-2.8 in the length from the 

 premaxillary symphysis to the hypural ; head, without the 

 opercular lobe, 2.5-2.4 in the same ; eye 4.1-3.1, snout 3.2-4.2 

 and interorbital space 4.2-4.6 in the head ; second dorsal 

 spine 2.7-2.2, and caudal fin 1.4-1.7 in the head. Golunr. — 

 Brown with numerous larger and smaller irregular spots and 

 blotches of darker brown ; a dark bar extends backward 

 from the eye to the shoulder, and all the head is more or less 

 spotted ; an interrupted band below the anterior dorsal spines, 

 and another between the soft dorsal and anal tins, while there 

 are several irregular patches on the caudal peduncle ; 

 membrane of the outer half of the spinous dorsal very dark, 

 that of the other fins greyish, the soft dorsal and anal with 

 their bases lighter. 



These specimens only differ from my description of G. 

 aprioii in having fewer scales on the lateral line. The figure 

 represents an example from Eidsvold 111 mm. long. 



A careful comparison of one of Krefft's specimens of 

 Mionorus lunatus from the Cox River, with those described 

 above does not reveal any important differences between 

 them, and indicates that it is only a local variation of G. glllii.
