| eae the present contribution, species belonging to seventeen families 
of Malacostraca and of Leptostraca are considered for various 
reasons, in several cases chiefly for the notes supplied by Mr. H. W. 
Bell Marley on the habits and colours of the freshly captured 
specimens. Among the Brachyura anomala a new species is described 
as Cryptodromia monodous. A new species is added to the Isopoda 
anomala under the name Haplocope oculatus. The Amphipoda are 
provided with three new species and a new genus, Wicrolysias, to 
which may be added a detailed account of Hxhyalella natalensis, both 
genus and species having been briefly introduced in December, 1917. 
But the point which has, perhaps, the best chance of exciting some- 
thing like general interest rests with the association of species from 
thirteen different genera found all sheltering in a single specimen of a 
sponge. It may be convenient here to bring together the names of — 
this motley assemblage of crustaceans. They are Hriphia scabriculus, 
Dana; Petrolisthes speciosus (Dana); Porcellana dehaanii, Krauss ; 
Processa sp.; Tanais phileterus, Stebbing ; Leptochelia dubius 
(Kroyer) ; Haplocope oculatus, sp. nov.; Paramera schizurus, sp. 
nov.; Hxhyalella natalensis, Stebbing; Hurystheus holmesi, Stebbing ; 
Cheiriphotis walkert, sp. nov., Podocerus inconspicuus (Stebbing) ; 
Nebalia bipes (O. Fabricius). Besides these there were other amphi- 
pods too mutilated after their Jong journey to repay investigation, 
and some miscellaneous objects, including a small star-fish. The 
protection which sponges afford to Crustacea has, of course, been long 
ago noticed by several writers, such as Canon Norman, the late H. J. 
Carter, F.R.S., and E. J. Miers. Also, M. Ed. Chevreux found 
twenty-three species of amphipods among the alien growths on the 
carapace of Mamaia squinado, probably distributed over several 
specimens. Similarly, it is not clear that the ten species in Dr. Willey’s 
gregarious Crustacea from submerged cocoa-nut piles in Ceylon were 
found together on any single pile.
