NO. 3582 GENUS ENTOMACRODUS — SPRINGER 89 



has 13 rays, the right 14; the pectorals of 13 paratypes counted had 14 

 on each side.) 



Proportional measurements: See tables 3, 4, and 39. 



No males with fleshy rugose modifications of the anal spines were 

 seen, although in the largest males the anal spines and anterior rays 

 were noticeably more fleshy than the remaining rays. 



The largest specimen examined was a male, 35.0 mm SL, the 

 holotype. The largest female examined was 27.1 mm SL. Males 

 and females were about equally common in the single large collection 

 made. The smallest specimen examined (see also material list) was 

 about 14.5 mm SL, not an ophioblennius stage, although posterior 

 canines in the lower jaw and vomerine teeth were absent. These 

 teeth were present in specimens 16.2 mm and larger. 



Twenty-six ophioblennius larvae, 15.0-19.5 mm SL (see material 

 below) from Oahu, Lanai, and Molokai, include 23 specimens which 

 could be E. sfrasburgi (the remaining 3 are E. marmoraius, as evidenced 

 by paired nuchal cirri on each side). These 23 specimens have the 

 following counts: segmented dorsal rays 14 in 12 specimens, 15 in 11 

 specimens; segmented anal fin rays 16 in 20 specimens, 17 in 3 speci- 

 mens; last anal pterygiophore supporting a single element in 5 

 specimens, 2 elements in 18 specimens. My reason for believing that 

 these larvae are not all E. mannoratus is based on the fact that only 1 

 of 92 recognizable specimens of E. marmoratus had a segmented dorsal 

 ray count of 14. 



Color pattern of holotype (preserved). — The ground color of 

 the sides of the body is pale. On the side below the soft dorsal fin 

 there are several groups of diffuse, dusky spots formed by loose 

 aggregations of melanophores. The side of the head is light dusky, 

 darker below the level of the orbit. There are faint indications of two 

 diffuse, dark, posteroventrally directed spokes from the ventral
