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

 a7id elsewhere hy Mr. Thomas Barbour in 1906-1907. By 

 Mary J. Rathbun. 



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

 except three 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 Ovvston. Other species 

 little known in collections are Utica nausithoe and Macro])hthalmus 

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

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

 Buitenzorg whicli represents a new type of the subgenus Parathelphusa.
