mark, thousands of these crabs, retreating before the encroaching sand, 

 congregated in heaps among the rocks near shore until the sand was washed 

 away again." 



Geograpsus grayi (Milne-Edwards).

 Edwards, Nouv. Archiv. Mus., 9, p. 288, pi. 16, fig. 1. 



One male and one female, agreeing well with Milne-Edwards's description. 



The species is widely distributed in Australia, New Caledonia, Mauritius. 

 Madagascar, &c. 



Mr. Oliver makes the following remarks on the habits of this crab, which 

 is almost terrestrial in habit : " This land-crab occurs sparingly on the 

 east coast of Sunday Island, and more commonly on Meyer Island and 

 other islets of the Herald Group. They make burrows little more in 

 diameter than the width of their bodies, and 6-20 in. long. Often, how- 

 ever, they are content with merely digging their way under a stone lying 

 on the surface. I have never found more than one crab in each burrow. 

 Their burrows are found in the forest at Coral Bay more than 100 yards 

 from the sea. The presence of shells and pieces of coral high up on Napi(M' 

 Islet can only be accounted for by supposing these crustaceans carried 

 them there, but for what purpose it is difficult to imagine. Mr. Roy Bell 

 tells me that land-crabs are in the habit of carrying shells from the rocks 

 up to where they make their burrows." 



Leptograptus variegatus (Fabr.).

Several specimens were taken at Sunday Island. The Canterbury 

 Museum collections also include one from the Kermadecs. 



In Miers's catalogue it is included in the New Zealand fauna on speci- 

 mens in the collections of the British Museum, but I do not knoAv from 

 what particular locality they were collected. 



The species is found on the coasts of Peru and Chile, at Juan Fernandez, 

 Australia, and other parts of the Southern Hemisphere. 



Cyclograpsus lavauxi (Milne-Edwards).

Three spirit specimens washed up on Low Flat Beach, Sunday Island ; 

 also two dried specimens in logs washed up on the beaches, Sunday Island. 



The species is common on New Zealand coasts, and is also found in 

 Australia.
