and the gills showing through the opercle as a bright pink 

 blotch ; the second dorsal and caudal fins beautifully pen- 

 cilled in alternate, narrow, obliquely transverse stripes of 

 black and white ; anal with a broad dark border ; ventrals 

 blue-black. In spirit, the yellow cross bands almost entirely 

 fade. 



Total length 4 to 5 inches. 



Hah. Vide Station 96. About 350 specimens of all sizes.

Allied to G. kaianus, Gthr., from the Arafura Sea. 

 Head large; tissues delicate.

The upcurved branchiostegal rays are prolonged con- 

 siderably beyond the suboperculum, so that the extreme length 

 of the head is three sevenths of the total without, and about 

 one third with, the caudal. The height of the low cylin- 

 drical body is one eighth of the first standard and much less 

 than the height of the head. Eyes large, their major dia- 

 meter being rather over one fourth of the extreme head- 

 length and one fourth longer than the snout ; they are sepa- 

 rated by a narrow shallow groove. 



Floor of the mouth darkly pigmented. 



Preopercular spine upcurved, very fine and acute ; its length 

 is two thirds the long diameter of the eye ; its base is ad- 

 vanced to form a forward-projecting sharp spine of consider- 

 able length ; and on its upper border, close behind the angle 

 of the preoperculum, are one or two rather procumbent 

 spinelets. 



The gill-opening is not much smaller than the orbit and 

 rather more on the flank than on tlie top of the head ; the 

 branchial arches are slender and flexible, the gill-rakers 

 almost rudimentary. 



The skin is loose and very thin. Lateral line single. The 

 first dorsal fin is lower than the second, its flexible spines 

 decreasing in length from before backwards ; the height of 

 the second dorsal and of the anal is not quite twice the 

 greatest body-height ; the length of the caudal is rather more 

 than one fourth of the total ; the pectorals are rather shorter 

 than the ventrals, which are as long as the postorbital portion 

 of the head and reach just beyond the origin of the anal when 

 laid back.
