Professor Herdman's collection of Macrurous Crustaceans from Ceylon consists of 

 53 species, of which 4 are new to science. 



With the probable exception of 3 species the collection is entirely typical of a 

 representative Indo-Pacific shallow-water fauna. Bithynis savignyi (Sp. Bate), 

 Athanas nitescens, Leach, and Urocans longicaudata, Stimpson, appear hitherto to 

 have had a known distribution limited to the Atlantic and the Mediterranean.
