The above description is based chiefly on the type (No. 2175 of 0. P. Jenkins’s collection, 50692, 
U. S. N. M. ), 2.6 inches long, from Honolulu, where Doctor Jenkins obtained 80 other examples from 
the coral rocks of the reef, ranging from 1.3 to 2.6 inches long. The species is known only from 
Honolulu and Waikiki.

Genus 209. HELICOLENUS Goode & Bean. 
Body oblong, somewhat compressed; head large, ctenoid scales on its tip, cheeks and opercles; 
several series of spinous ridges on head, but no occipital pit; mouth large, with bands of villiform 
teeth on jaws, vomer, and palatines; dorsal fin continuous, not deeply notched, with 10 stout spines and 
10 to 12 rays; anal with 3 spines and 6 rays; pectoral broad, fan-shaped, with rays arranged in 3 
groups, the first of 2 simple rays, the second of 8 or 9 branched rays, the third of 8 simple rays, some- 
times prolonged, with their tips tendril-like and free from membrane for one-half their length or less; 
soft dorsal with tips free from membrane; suborbital keel smooth, or with a single anterior spine 
under eye; preobital with spines small and hidden beneath skin; vertebra 10+ 14=24; no air-bladder. 
Very close to Scorpiena, differing only in the Sebastes-like cranium, the 2 genera probably connected 
by intermediate forms. 
The single Hawaiian species of this genus is fully described in Section II. 
Helicolenus Goode & Bean, Oceanic Iehth., 248, 1896 (dactylopterus) .

all simple and only their tips free; 6 to 9 rays in the anal; the suborbital keel composed of 3 distinct, 
differentiated, flat, knife-like spines; 2 prominent retrorse spines on each suborbital. 
The single Hawaiian species of this genus is fully described in Section II.
