A single specimen from Christmas Island extends the range of 



this species. Dr. Willey collected it at Sandal Bay, Lifu, and 



Sluiter, who described the species, records it amongst the Malay 



Gephyrea, but unfortunately gives no more precise locahty.

 A single small specimen measuring some 2 cm. in length. Dr. 

 W. Fischer has I'ecently recorded it from Thursday Island, Samoa, 

 whence it extends throughout the south-west Pacific and Indian 

 Oceans.

 One specimen, which, like those collected by Mr. Stanley 

 Gardiner at Funafuti and Eotuma, was very much longer than 

 the examples described by Sluiter. He, however, found no repro- 

 ductive organs, so that it is possible his form was immature and 

 not fully grown. The characteristic long nephridia reaching to the 

 posterior end of the body — also found in Ph. pacijicum — are well 

 marked.
