(Dr. Andrews's) visit to the island in 1908, lie obtained 

 specimens of a large Megalopa-larva, whicli occurred in 

 enormous quantities in the sea shortly after the migration, 

 and also of a small crab which appeared in similar numbers 

 at a slightly later date. It seems practically certain that 

 these larva3 and young can belong to no other species than 

 G. lalandii, and it is hoped that it may be possible to obtain 

 the earlier stages and to give a complete account of the 

 life-history."

Unfortunately, up to the present no earlier stages liave 

 been collected, so this description includes only the megalopa 

 and young post-larval stage mentioned above. It seems 

 probable, however, from the large number and small size of 

 the eggs carried by the berried female, that the young do 

 hatch at an early stage, probably as a zocii or protozoea.
