REPORT 



ON THE 



PANTOPODA 



COLLECTED BY 



Professor HERDMAN, at CEYLON, in 1902.

[With ONE PLATE.] 



The Pycnogons collected by Professor Herdman and his colleague comprise two 

 species, both obtained in comparatively shallow water in the Gulf of Manaar and 

 along other parts of the Ceylonese coast. One belongs to Nymjjhon and the other 

 to Phoxichilus, both widely distributed genera, ranging from the Arctic Ocean to the 

 southern seas. Nym/phon is, however, a genus much richer in species, and shows a 

 wider distribution than Phoxichilus. Both the forms seem to be referable to new 

 species, and as numerous individuals have been collected in an excellent state ot 

 preservation, it is easy to describe and figure their distinctive characters. The 

 Nymphon is abundantly distinct from any known species. Phoxichilus, on the other 

 hand, is a genus whose named forms are of doubtful "specific" value. But all the 

 more on that account is a careful study of specimens from new localities desirable as a 

 guide to the extent and nature of variation. 



I am much indebted to Professor Herdman for entrusting me with this interesting, 

 if small, collection for examination and report.
