Z SLAUEN TRUST EXPEDITIONS TO ABROLHOS ISLANDS. 
Tlie main interest of the collections lies in the bearing which it has on the 
general question of the origin oi: the fauna of the Abrolhos Islands. As 
Professor Dakin has already pointed out, these islands are remarkable as 
being the most southerly islands in the world with coral reefs fringing their 
shores, and this fact would suggest that the fauna of the islands should, in 
the main, bear a strong tropical facies. The Ainphipoda in this collection 
bear out that suggestion. I have in the following table indicated the known 
geographical distribution of all the species in the collection. It will be seen 
at once that six of them have a wide distribution in the tropical and sub- 
tropical waters of the Indian and Western Pacific Oceans, ranging from 
South and East Africa to the Oceanic Islands of the Pacific. Two other 
species, Pa»'Aar^i»iia villosa and Griibia setosa, have so fiir onl}' been met with 
in the waters round South and East Australia an<l New Zealand. Only one 
species, Paraivaldeckia kidderi, seems to be a migrant from the Southern 
waters of the Antarctic sub-Polar seas. 
Of the Isopoda, two species are described as new, but all three species in 
this collection belong to the Spha3romida3. a family of Isopoda characteristic 
of the warmer waters of the globe.
