No. 16. — Decapod Crustaceans collected in Dutch East India 

 and elseivhere by Mr. Thomas Barbour in 1906-1907. By 

 Mary J. Rathbun. 



All the species noted were collected in the Dutch East Indian islands 

 except tln-ee of the Potamonidae and one Bithynis from the fresh waters 

 of northern India and the rare Thaumastocheles zaleucus from deep water 

 off Japan, which was acquired through Mr. Alan Owston. Other species 

 little known in collections are Utica nausithoe and MacrophtTialmus 

 definitus. Despite the extensive explorations by the Dutch in Java, 

 Mr. Barbour's collection yields an undescribed species of potamonid from 

 Buitenzorg which represents a new type of the subgenus Parathelphusa.
