Material. — 1 d\ 72.8; Mayotte Id., Comoro Islands; intertidal 

 zone; A. Crosnier; September 1959; MNHNP. 1 cf, 59.7; Anjouan 

 Id., Comoro Islands; intertidal zone; A. Crosnier; November 1961; 

 USNM. 



Remarks. — The specimen from Anjouan Island has two commensal 

 gastropods attached to the pleopods. Holthuis (1951) has commented 

 on the occurrence of a gastropod, Caledoniella montrouzieri Souverbie, 

 on specimens of Gonodactylus chiragra. As far as I can determine, 

 no commensals have been reported for 67. platysoma. 



Distribution. — Indo-West Pacific, from scattered localities be- 

 tween the western Indian Ocean and Oceania.
