70 PROCEEDINGS OF THE NATIONAL MUSHUM VOL. 120 
coral in shallow, sandy beach, May 11, 1957, Bredin Exped., 1 male, 
1 ovig. female. 
MEASUREMENTS.— Males, 7-28 mm.; females, 10-15 mm.; ovig. 
females, 10-21 mm.; juv., 6 mm. 
Remarks.—In previous papers (Stephenson and Hudson, 1957; 
Stephenson, 1961a) Edmondson’s species was included as a queried 
synonym. Doubt arose from minor differences between the male 
pleopod as figured by Edmondson (1954, figs. 34g, h) and those of 
the single male available from Australia. Edmondson showed two 
terminal spinules on the inner surface, which had no counterpart in 
the Australian specimen, and five instead of three subterminal spinules 
on the outer surface. 
The present material shows variability in armature of male pleopods 
(see table 2, p. 114). 
DisrrisutTion.—Western Australia and Hawaii (Edmondson, 1954; 
Stephenson, 1961a).

Nore ON SYNONYMY AND NOMENCLATURE.—Crosnier (1962), in 
describing 7’. foresti, revised the synonymy of TY. danae. To his 
synonymy, Sakai (1939) is now added. 
MarrriaL.—Two forms are recognized in adult males, called forms 
A and B, respectively, distinction being by male abdomens and ple- 
opods. ‘These are listed separately as are females and juveniles.
