Palcemon, species n. 



f found by me in estuaries which occasion-

 I S.W. point of Mindanao, Philippine Islands — 

 Oammarus, species October 15, 1859, by my diary. The typical 



Cyclops, species genus PalEemon is a true fresh-water form ; 



almost all the species live in pure fresh water, 

 and inany occur high up in mountain streams 

 as far as 6,000 feet above the sea. Only the 

 two species here mentioned occur in brackish 

 water or on the sea-shore. PaVsmon Idee I also 

 found in the harbour of Hong Kong. 

 Astacus. — Two species in the Caspian Sea ; associated with marine 

 species (Biohwald, Arcli.fiir Natnrg., iv. Jahr.). 



Bva/ncliipus stagnalis, a typical fresh-water form, is said by Braun to 

 grow much larger in salt than in fresh water, but he does not mention 

 whether the Crustacean remains otherwise unaltered. 



Daphnis rectirostns and other species live, according to Sohmanke- 

 witsch, equally well in salt and fresh water, but they exhibit certain 

 differences depending on the medium. 



2. Arachnida.— Sea.-Toites are by no means rare. Grosse ha.s described 

 thr'ee English species {Ann. Nat. Hist., ser. 2, vol. xvi. pp. 27, 305). 

 Pontarchus was found by Philippi on the shore at Naples.
