no. 3641 STOMATOPOD CRUSTACEA — MANNING 43 



telson. Species in this section include the three species reported below, 

 G. chiragra (Fabricius), G. platysoma Wood-Mason, and G. smithii 

 Pocock. It is suggested below that G. acutirostris de Man is based on 

 an aberrant specimen, and that de Man's species is conspecific with 

 G. smithii. 



The "falcatus section" includes only two species, G. falcatus (For- 

 skal) and G. graphurus Miers; these species have small ocular scales 

 and five carinae on the median area of the telson. Manning (1966) 

 and others have pointed out that the latter species does not occur 

 west of Indo-Malaya and that earlier records to it in the literature 

 from the western Indian Ocean are referable to G. falcatus. 



The "demanii section" includes 10 small species, mature at TL 

 50 mm or less, seven of which were reported by Manning (1967b). 

 Three additional species are reported below from Madagascar, in- 

 cluding one species revived from the synonoymy of G. chiragra and 

 two described as new.
