E. fragilis is endemic to the Hawaiian Islands (Fig. 12). The spe- cies is demersal and has been taken between 120 and 125 meters. Taxonomic notes. Six years after E. fragilis was described, Fowler (1928) syn- onymized the species with a second Ha- waiian apogonid, Hijnnodus atherinoides Gilbert, 1905. The synonymy achieved moderate acceptance and appeared in sev- eral publications (, Matsubara, 1936; Tinker, 1944; Gosline and Brock, 1960). Fowler's conclusions were based on a 33-mm specimen (BPBM 3914) obtained by the Tanager Expedition. The specimen is in extremely poor condition. All colora- tion has been lost, most of the muscle tissue has decomposed, and much of the skeleton has become decalcified. Although it is impossible to identify the fish because of its condition, the following traits suggest it is neither E. fragilis nor H. atherinoides: dorsal fin elements—VIII-1,8; anal fin ele- ments—11,6; vertebrae
