348 DR. W. M. TATTERSALL ON THE STOMATOPODA AND 



Macrurous Decapoda of the Red Sea and the Malay Archipelago than 

 is possible for any other region. 



57 out of 176 Red Sea species, or 33 per cent., are known from the 

 Malay Archipelago and its adjacent waters. This percentage agrees 

 closely with that given by Laurie for the Brachyura of the Red Sea 

 compared with the Seychelles, Maldive Archipelago, Cevlon, and the 

 Hawaiian Isles. 



The Siboga Reports on the Penseidse and the Alpheidse provide 

 interesting results. 



9 out of 19 Red Sea species of Penreidfe or 47'5 per cent., and 29 

 out of (19 Red Sea species of Alpheidfe or 42 per cent., were taken by 

 the Siboga Expedition in the waters of the Dutch East Indies. 



East Coast of Africa. Borradaile, 1910. Lenz, 1905 and 1910. 

 Miers, 1884. Ortmann, 1894. 

 29 out of 176 Red Sea species, or lti - 5 per cent., are known from 

 this region. 



It is obvious from these results that much remains to be done before the 

 Macrurous Decapoda of the Indo-Pacific can be said to be fully known. 

 So far as they go, they support Laurie's contention that the fauna of the Red 

 Sea forms an integral part of the fauna of the Indo-Pacific Ocean. 



To save frequent repetition I give a list of stations from which the present 

 collection was made. It has been compiled to suit the present report, from 

 Laurie (1915, p. 419). Crossland (1907) should be consulted for a detailed 

 account of the collecting grounds.
