Ophichthys marmorata, Gunther (1910: 404) 
(Hawaii) . 
Callechelys marmoratus, Fowler (1928: 43) (Ho- 
nolulu market). 
MATERIAL EXAMINED: 2 Specimens from 
Oahu, 1090 and 560 mm. in total length. The 
larger was grabbed by hand by Mr. V. E. 
Brock as it rested mostly buried in the sand; 
the smaller swam into a night light. 
To enable comparison with the data on the 
genus assembled by Storey (1939), the fol- 
lowing characters of the two specimens men- 
tioned above are given, those for the smaller 
in parentheses. Greatest depth 40.8 (49.6), 
head to gill opening 18.5 (18.8), trunk 1.8 
(1.9), and tail contained 2.5 (2.3) times in 
total length; head 10.0 (9-7) and tail 1.3 (1.2) 
in trunk; snout to rictus 3.6 (3.9) and snout 
to dorsal origin 2.8 (2.8) in head; distance 
between gill openings 1.3 (1.2) in length of 
gill openings; angle of gill openings 130° 
(125°). In these characters my two specimens 
check far better with Storey’s data on C. luteus 
than on C. marmoratus or C. guichenotii. 
MYRICHTHYS Girard 
In the Hawaiian region the genus may be 
sufficiently distinguished as follows: Dorsal

head indicated. 
commencing forward of the gill openings. 
Pectoral present, its base broader than its 
length. Teeth blunt and granular.

Myrichthys stypurus, Jordan and Evermann 
(1905: 85, fig. 19) [on Smith and Swain’s 
type]. 
Ophichthys maculosus, Gunther (1910: 40) (Ha- 
waiian Islands). 
Myrichthys maculosus, Fowler and Ball (1925: 
6) (Johnston Island); Fowler (1928: 43) 
(Johnston Island and Honolulu). 
MATERIAL EXAMINED: 13 Specimens from 
Oahu and 1 from Midway in the University 
of Hawaii Collection; 1 specimen from Ho- 
nolulu in the Bishop Museum. 
This species seems to be distributed from 
the Red Sea to Hawaii. It has been taken in 
the Phoenix (Schultz, 1943: 14) and Line 
Islands (Fowler, 1927: 5) south of Hawaii, as 
well as at Johnston Island. 
8. Myrichthys bleekeri substitute name 
Ophisurus fasciatus var. semicinctus Bleeker [non 
0. semicinctus Lay and Bennett (1839: 66) 
non 0. semicinctus Richardson (1844: 99)] 
(1864: 64) (Indonesia). 
Myrichthys coluhrinus, Fowler and Ball (1925: 
5) (Johnston Island); Fowler (1928: 42) 
(in part; the Johnston Island specimens). 
MATERIAL EXAMINED: 8, 335-385 mm., of 
the 12 specimens recorded by Fowler and Ball 
and by Fowler from Johnston Island, in the 
Bishop Museum Collection.
