ICHTHYOLOGICAL ITEMS.— McCULLOCH. 69 



in three of the specimens : in Ogilby's type it is a crescentic appendage formed of 

 two divergent, fleshy lobes, behind which is a low, broad, petiolate flap ; in the 

 small Western Australian specimen, the spine is surmounted by several fleshy ten- 

 tacles of difl^erent lengths, behind which is a skinny sheath which is as long as the 

 rest of the spine ; the terminal portion of the Brighton and large South Australian 

 specimens consists of two long branches -with tAvo basal flaps as figured bj^ McCoy. 

 I have no doubt that these differences are either individual variations or are due to 

 the different state of preservation of the specimens, and regard all three as referable 

 to the one species. 



The small Western Australian specimen is quite similar to the larger Brighton 

 example in its colour-marking, and both only differ from McCoy's figure in having 

 the dorsal fin and an area along its base enclosed in a large, well-defined, white patch ; 

 in the largest specimen no such white patch is present, but the dark markings are 

 more extensive and more pronounced than in the figure. Ogilby's specimen has 

 become stained an almost uniform brown after long preservation in spirits.
