distribution. This species, indeed, occurs in the eastern Atlantic from the south coast of Norway 

 to Cape Town and Kast London, in the Mediterranean, the Adriatic and the Black Sea, also 

 in the western Atlantic from off North Carolina and the Bermudas to the Gulf of Mexico, 

 Porto Rico and Trinidad; it was recorded from Ceylon and Japan and is distributed on the 

 west coast of America from San Diego, California, to Panama Bay. Still another species is 

 known from the Gulf of Gascony, viz. : Proc. platyura (Fischer), which, however, as far as I 

 am aware, has not been found elsewhere. 



The other species are confined to the Indopacific. In the Red Sea Proc. aegu iwana (Pauhon) 

 and Proc. Coutierei Nobili are found, in the Gulf of Martaban occurs Proc. processa (Bate), 

 and Proc. macrognatha (Stimps.) from Hong Kong was recorded by the author of this Report 

 from the Mergui Archipelago; besides Proc. canaliculata still two other species, Proc. japonica 

 (de Haan) and Proc. processa (Bate), are known from Japan, the Hawaiian Islands are inhabited 

 by Proc. hawaicnsis (Dana) and Proc. processa (Bate), while four or perhaps a few more species 

 are distributed throughout the Indian Archipelago, viz. : Proc. processa (Bate), Proc. japonica 

 (de Haan), Proc. australiensis Baker and the forms that will be described under the name of 

 Processa sp. Two species, finally, are known from the South Australian coast, Proc. austra- 

 liensis Baker and Proc. o-racilis Baker. 



Concernino- the vertical ranste of Proc. canaliculata Leach Mr. Stanley Kemp in his 

 valuable work "The Decapoda Natantia of the Coasts of Ireland" remarks that it is found off 

 the Irish Coast between 3 and 199 fathoms, but that it is apparently of rare occurrence outside 

 the ioó fathom line. Off the american coasts it ranges from shallow water to 1 1 1 fathoms 

 (Rathbun), while in the Mediterranean it has been recorded from depths of 2 1 6 fathoms (Senna) 

 and 326 fathoms (Adensamer). The indopacific species occur in shallow water, as far as their 

 vertical range is known ; the greatest recorded depth is 7 1 fathoms, at which Proc. processa 

 was taken in Japan; one species was obtained on the N. W. coast of Waigeu-island at 45 and 

 another off the Hawaiian Islands between 2 1 and 43 fathoms, but often species were taken in 

 more shallow water and on the reef.
