Eurythoe complanata as here accepted has an almost cosmopolitan distri- 

 bution in the warmer latitudes. It is abundant and very widespread on the 

 coasts of the Indo-Pacific region from East Africa and the Red Sea to the Phil- 

 ippines, Hawaiian Islands and the Galapagos, without, however, having been 

 taken on the western American coast, and it occurs as well in the Atlantic in 

 the West Indies and on the African coast at the Canaries, etc. On the west 

 coast of America it is represented by a smaller but very closely related form, 

 E. pauper a Grube {E. calif ornica Johnson) which occurs in the littoral zone
