not much use, except locally, can be made in practical classification 

 of the several (eight) varieties recognized by Lendenfeld, (1889). 

 The distribution of the species recorded by Lendenfeld is wide, 

 including the Mediterranean, Indian Ocean, Pacific, American coast 

 of North Atlantic, and Australian seas. Since Lendenfeld's mono- 

 graph the species has been recorded for Amboina (Topsent, 1897, p. 

 482), Porto Rico (Wilson, 1902, p. 405), Azores (Topsent, 1904, p. 

 250), Chilean waters (Thiele, 1905, p. 484), Sudanese Red Sea (Row 

 1911, pp. 371, 372), Spanish waters (Hernandez. 1916 p. 39, 1918 

 p. 33, 1921 p. 2).
