130 RECORDS OF THE. AUSTRALIAN MUSEUM. 



First dorsal spine inserted above tlie twelfth bodr-scale, and much 

 nearer the hypural joint than the end of the snout ; its tirst spine is a 

 little longer than the second, but not quite so long as the second dorsal ray, 

 and reaches lialt its distance from the base of the fourth dorsal ray. Soft 

 dorsal originating over the twent3'-second or twenty-third body-scale, 

 emarginate ; the space between the origins of the two dorsals equals the 

 length of the head. Anal originating below the twentieth body-scale and 

 terminating below the middle of the dorsal ; its base is shorter than its 

 distance from the hypural joint, and its margin is excavate. Pectoral fin 

 reaching tlie tenth scale but not attaining the vertical of the dorsal origin. 

 Veiitrals inserted just behind the vertical of the middle of the [)ectoral and 

 nearer the anal fin than the end of the snout ; it reaches backward to 

 below the middle of the first dorsal. Caudal fin emarginate, the lobes 

 pointed. 



Bleached after long preservation. A dark spot at the base of the 

 pectoral, and the margin of the caudal fin blackish. 



Described from the holotj'pe of the species, 180 mm. long to the end 

 of the middle caudal rays, which was presented to the Australian Museum 

 by Mr. J. Douglas Ogilby. The accompanying figure represents a larger 

 specimen 231 mm. long, from Pott Hacking, in which the pectoral and 

 ventral fins do not reach quite so far back as in the smaller holotj'pe, and 

 the anal is placed rather farther back in relation to the second dorsal. 



SijiioinjtHii. — According to Mr. H. A. Longman, no specimen now in 

 the Queenslatid Museum can be definitely identified as the type of J/. 

 tiortoui, Ogilby, but an example 165 mm. long, which was incorrectly 

 registered as 3/. steve)isi by Ogilby, agrees sufficiently well with the 

 description of M. nortoni to leave no doubt as to its identity with that 

 species. I liave been enabled to compare this with the holotype of M. 

 georgii in the Australian Museum, and can find no characters to separate 

 the two as distinct species.
