FISHES OF THE PHILIPPINE ISLANDS AND ADJACENT SEAS 243 



1% to 1%; caudal 1% to I14, very slightly concave behind, as ex- 

 panded nearly truncate ; least depth of caudal peduncle 21^ to 2% ; 

 pectoral II/2 to 1% ; ventral li/<} to 1%. 



Brown generally, paler below or on under surface of head and 

 abdomen. Narrow whitish band begins on middle of interorbital, 

 forks at occiput and extends along each side of spinous dorsal base 

 to soft doi*sal origin. A second narrow whitish band begins each 

 side of snout tip, extends over nostrils and eye, across supraoccipital 

 and then gradually wider to last dorsal ray bases, including upper 

 caudal peduncle edge and obliquely over caudal to hind median 

 caudal edge. Third less distinct, extends from below eye above 

 pectoral fin origin nearly to bases of lowest caudal rays and then 

 out over lower caudal rays to join upper band at hind caudal edge. 

 Iris light yellowish. Spinous dorsal pale brown, edge narrowly 

 dusky. Soft dorsal blackish brown, with horizontal whitish bands 

 and hind edges of last short rays whitish. Caudal largely blackish 

 brown, except for oblique terminals of white bands from body ; outer 

 portion of upper lobe with blackish brown corner and oblique 

 blackish brown bar; lower lobe with broad blackish brown corner. 

 Anal largely blackish brown. Pectoral pale brown. Ventral dusky 

 brown. 



Red Sea, Zanzibar, East Indies, Micronesia, My two larger ex- 

 amples differ a little as they have only the two white upper longi- 

 tudinal bands distinct, the whitish band on the soft dorsal and dark 

 blotches on the caudal largely absent. They have, however, the 

 ventrals and anal both neutral dusky.
