52 CRUSTACEA PROM PORT CURTIS DISTRICT, QUEENSLAND, 



series from the Malay Archipelago and Australia demonstrate 

 that the differences are of a specific value, Haswell's name of 

 deflexifrons will stand for our specimens. 



Miers (loc. cit.), who has compared Australian specimens with 

 the type in the British Museum, has given a detailed description, 

 with which our example is in accord except that the fingers, 

 which are said to be "rather shorter than the palm," are with us 

 scarcely half its length. In this it is in agreement with 

 G. longirostris Dana, which, however, appears to have a shorter 

 cheliped, "as long as the body." 



There is in the Australian Museum an unlocalised specimen in 

 which the rostrum is slightly deflexed, being intermediate between 

 the type of G. deflexifrons Haswell, and typical forms of G. elegans. 

 It appears to us to afford ample confirmation of the view of 

 Miers that the two species are identical, the one which we have 

 here adopted. 



Henderson* has expressed a view that this species is identical 

 with G. grandirostris Stimpson, but with this we cannot agree. 



The colour of the species is most variable; our specimen from 

 Port Curtis was, when alive, a bright scarlet with a central 

 longitudinal purple band only on the last segment of the 

 abdomen.
