portion of cp.,uda,l yellow spotted with brown, lower portion 

 violet with a ppoler ma,rgin ; i)ectorals dull yellow, 

 immpoculate ; ventra,Is yellowish, the ground color almost 

 wholly obscured by violet dots, among which are scattered 

 numerous white da^rk- edged ocelli, and, near the tip, a few 

 blackish spots. A second specimen (? $ ) differs in being 

 of a general darker colorp.tion above, the clear golden brown 

 being replaced by violaceous brown, which color extends 

 further down the sides, somewhat obscuring the lateral 

 series of spots and terminating inferiorly in 12 or 13 short 

 blunt processes, which encroach upon the pure white of 

 the under parts. The fins correspond in general pattern 

 with those of the larger example, but the cross-bands on 

 the spinous dorsal are indistinct, and the pectorals are gray, 

 their rays alternately banded with gray and lilac. (Named 

 for my friend and colleague, the late Major George Gross, 

 one of the leading conchologists of Queensland.) 



Described from two Moreton Bay specimens, measuring 

 respectively 128 and 112 millim., in the collection of the 

 A.F.A.Q. ; Cat. No. 958.

There is a remarkable resemblance in some of the 

 generic characters between Dactylopus and the rare Japanese
