r B'ound by me in estuaries which occasion- 

 ally contain strongly salt water, at Zamboanga, 

 S.W. point of Mindanao, Philippine Islands — 

 October 15, 1859, by my diary. The typical 

 genus Palsemon is a true fresh-water forrn ; 

 \ almost all the species live in pure fresh water, 

 and many occur high up in mountain streams 

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

 two species here mentioned occur in bracWsh 

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

 l^found in the harbour of Hong Kong. 

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

 species (Eichwald, Anli.fiir Natwg., iv. Jahr.). 



Brmioliipus gtagnalis, 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 CrustaoeSan remains otherwise unaltered. 



Daphnia rectirostris and other species live, according to Schmanke- 

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

 differences depending on the medinrn. 



2. Araclmida. — Sea-mites are by no means rare. Gosse has described 

 three English species {Aim. Nat, Hist., ser. 2, vol. xvi. pp. 27, 305). 

 PontaroJiiis was found by Philippi on the shore at Naples. 

 Thalassa/i-aeJuia Vei-rillii (Pack.) lives in deep water off the American 

 coast (SilHman's Am-. Jom-n., 1871, February). I myself have fomid
