and dashes separated by paler interspaces that extend onto the 

 ventral preopercidar area. (The posterior margin of the preopercular 

 area is diffusely pale and dusky, lighter than the almost uniformly 

 dusky opercular area.) Below the eye (6 o'clock position) is a dusky 

 band extending to the dorsal margin of the upper lip. Within the 

 band are the pale openings of pores. The upper lip bears 20 vertical 

 dark stripes of varying width and intensity, separated by paler inter- 

 spaces. These stripes extend onto the snout, where they may take 

 the form of spots. The imderside of the head is dusky with the area 

 just behind the lower lip darkest. 



Except for the darkened area where the spots on the body enter tlie 

 spinous dorsal fin, that fin is more or less uniformly dark dusky. The 

 membrane of the soft dorsal fin is also dusky but the spines are mostly 

 pale and there are several fine pale diagonal stripes coursing over the 

 fin. The anal fin is uniformly dark dusky. The caudal fin is pale 

 dusky with three darker vertical stripes on the proximal portion, the 

 two posterior stripes not entering the dorsal third of the fin. There are 

 two dark spots on the central caudal base. The pectoral fin is uni- 

 formly dusky. The fleshy pectoral base bears several small dusky 

 spots. The pelvic fin is dusky, with the rays paler than the webbing. 



The color patterns of specimens (Indian Ocean) in a single collection 

 are quite variable. The body spots may be fused into solid bands (pi. 

 10a), limited only to the middle spots of each vertical series, or absent. 

 The body may bear numerous scattered, small, dusky spots (pi. 106) 

 or may bear vertical paired series of spots and scattered small dusky 

 spots, somewhat paler than the vertical series. No specimens were 

 seen which had a humeral blotch, as found in some specimens of E. 

 niuafoouensis and all E. randalli. The imderside of the head may bear 

 diffuse dark chevrons, the middle two joined to form a Y, or may be 

 entirely pale. The side of the head may be pale with the only dark 

 mark a black elongate spot behind the eye. The lip stripes may be 

 pale to absent, or fused, and represented as a few diffuse, dusky and 

 pale bands. The fins may be variably dusky spotted; the fleshj^ pecto- 

 ral base may bear two dark stripes separated by a broader, paler inter- 

 space. Females do not appear to differ much, if any, in coloration 

 from males, although in specimens from the same collection the fe- 

 males are less intensely marked than the males. 



Two specimens from Tutuila, the only specimens of the species 

 known from the Pacific Ocean, differed from the other specimens pri- 

 nuirily in having the soft dorsal fin darkly spotted, with about three 

 spots over each ray, and in having numerous pale spots on the ventral 

 portion of the body sides. 



Remarks. — There is a tendency for males from the Indian Ocean to 

 have higher numbers of segmented dorsal fin ravs than females. Of 41
