Habitat. — A considerable number of specimens were 

 obtained amongst Algse and barnacles scraped from a ship's 

 bottom at Granton Harbour ; most of the specimens were 

 either females or immature, but a few adult males were 

 found, by means of which the species to which they belonged 

 was satisfactorily identified.
