Discussion. — I believe Lanchester (1903) was correct in suggesting 

 that G. acutirostris de Man was based on a specimen with a damaged 

 telson, with the deformity affecting the posterior end of the median 

 carina and the anterior ends of the carinae of the submedian teeth. 

 In other respects, including the sharpness of carinae on the telson and 

 the acute anterolateral angles of the rostral plate, it agrees with G. 

 smithii Pocock. There is little doubt in my mind that G. chiragra var. 

 intermedia de Man, from Pulau Berhala, is conspecific with G. smithii; 

 it agrees with the latter species in all respects. 



Odhner (1923) pointed out that Kemp (1913), in his account of 

 G. acutirostris, misunderstood de Man's original description in stating 

 that G. acutirostris lacked the anterior tubercles on the telson; Odhner 

 pointed out that these tubercles were present, but that the type lacked 

 the flukes of the anchor. In my account of G. smithii (1966) from 

 Australia, I made the same error in pointing out differences between 

 my specimens and G. acutirostris. De Man (1929) noted that in the 

 type of G. acutirostris the anterior tubercles were present. 



Specimens of G. smithii from Australia differ from those reported 

 here in having a broader endopod on the uropod, on which the inner 

 margin is convex. In the specimens from Madagascar the inner margin 

 of the uropodal endopod is sinuous, convex proximally, concave 

 dis tally.
