this species in the monotypic genus Desmo-
holacanthus. Toyama (1988) wrote an article
on this and other angelfishes of Midway.
Genicanthus personatus Randall, 1975
Plate IIIE,F
BPBM 31971, 6: 136-160 mm; BPBM 34774,
133 mm; also six specimens donated by us to
the U.S. National Museum of Natural His-
tory (USNM 308842). Fairly common at sec-
tions of reef with ledges and caves outside the
lagoon at depths of 20 m or more. This is an
example of a species that is found in the main
Hawaiian Islands in deeper depths than nor-
mally penetrated by Scuba divers. Previously
reported from Midway by Toyama (1988) and
Pyle (I 990b).
Family Oplegnathidae (Knifejaws)
Oplegnathusfasciatus (Temminck & Schlegel,
1844)
Figure 55
Occasional both within and outside the
lagoon in reef areas, generally in less than
10 m. Well known from Japanese seas. This
and the following species are rare in the
main Hawaiian Islands. We have seen only
one photograph of a subadult of O.fasciatus
from the island of Hawaii.
Oplegnathus punctatus (Temminck & Schlegel,
1844)
Figure 56
Occasional; seen on reefs within and out-
side the lagoon, usually in less than 10m, most
often in or near caves. This and the above
species seem to be immigrants to the Hawai-
ian Islands from Japan. The Bishop Museum
has adult specimens from Kure Atoll, Maro
Reef, Oahu, and Maui.
Family Mugilidae (Mullets)
Mugil cephalus Linnaeus, 1758
Recorded from Midway by Uchida and
Uchiyama (1986).
