actually inhabitants of the sea, although found on the sea coast, 

 were purposely omitted. 



Those contained in the following list are usually found among 

 mangroves, on muddy flats, or under stones at the sea-side which 

 are sprayed by the action of wind and wave. 



Compared with tropical areas our fauna of this class is not 

 numerous. 



The references given are confined to the original description, 

 and one where the species is figured is given. Synonyms that are 

 generally known are also referred to. 



The list includes nine genera, comprising twelve species.
