nape in mid-line before dorsal; cirri of nuchal combs in fish of about 40 mm. 

 begin to branch from the base, half the cirri double in specimens of 50 mm., half 

 trifid at 57 mm., the proportion increasing in larger ones with the result that the 

 comb is composed of tufts of about three elements standing in series on the short 

 and thin basal lamina.

Variation in dorsal and anal fin formulas in Labrisomus guppyi 



The type of Malacoctenus bondi is not well preserved, at least as to color. The 

 pectoral fin is indeed dark basally, but the suggestion of ocellation in the figure 

 accompanying the original description apparently was derived largely from 

 artifact. The fish seems structurally the same as the type of Clinus guppyi, and it 

 has precisely the same fin formulas, though in the figure the dorsal spines shown 

 are 2 too many and the soft rays correspondingly too few.
