DeEscrIPTION.—See Lewis (1967). 
REMARKS.—Based on the examination of the Eniwetok material and 
a comparison of this material with the Hawaiian specimens (USNM 
112912, 112913), two additions should be made to the description in 
Lewis (1967): 
1. There are 2 adhesion processes on the male antenna, the first 
(op. cit., p. 186) is a ridged, lappet-like adhesion pad on the distal 
inner surface of the second segment while the second (not previously 
described) extends, as a narrow band, from the proximal anterior 
surface to the distal inner surface of the second segment. This ad- 
hesion band is more distinct in the Eniwetok specimens than in those 
from Hawaiian fishes. 
2. The positioning of the denticulations shown on the second 
segment of the endopodite of the second thoracic leg in Lewis (1967, 
fig. 51c) is incorrect for the appendage in situ. For detailed examina- 
tion and camera lucida drawings, the thoracic legs are normally 
removed and mounted under 9 mm cover slips. This technique fre- 
quently causes the arrangement of the denticulations on the second 
seement of the endopodite of the second thoracic leg to be distorted. 
In the appendage in situ, on both Hawaiian and Eniwetok specimens, 
the denticulations are typically arranged in pairs (except for the 
single proximalmost denticulation), straddling the outer surface of 
the segment (as shown in Kabata, 1965c, fig. 18).
