MareErtaAL.—Tuamotus and Societies: Both coll. Bredin Exped., 
Huahine Is., Sta. 84a-57, head of Baie de Maroe, from branching 
coral, Apr. 5, 1957, 1 male (6 mm.). Tickahau Lagoon, Sta. 10a-57, 
Apr. 11, 1957, 1 ovig. female (9 mm.). 
Remarks.—lIf Tesch (1918, pp. 177-178) is correct in stating that 
there are no reasons for maintaining the genus Catoptrus A. Milne 
Edwards, 1870, then the above synonymy follows. 
Serene (pers. comm.) has drawn our attention to Barnard’s sugges- 
tion (1954, p. 100) that C. inequalis Rathbun (1906), which is very 
close to the present species, may be a synonym of L. edwardsi Alcock 
(1900). 
The male abdomen resembles that figured by Crosnier (1962, fig. 
14); unfortunately no male pleopods are present so that Edmondson’s 
(1954) figures 2f and g cannot be checked. 
DistTRIBUTION.—Madagascar to Hawaii, including Mauritius, 
Amirante, Coetivy, Ceylon, Amboina, Batavia, Japan, Samoa, and 
Fiji.
