seaboard of Great Britain and from the Irish Sea,* but it is absent from the east 

 coast of England and Scotland ; this limited distribution in northern areas may be 

 accounted for by the influence of the Gulf Stream on the west British coast. Dr. 

 Egger obtained it from " Gazelle " dredgings in the Mauritius and at Amboyna. 

 Present Occurrence. — Off the Snares ; 60 fathoms ; frequent.
