Family : OMMATOSTREPHIDAE 



Subfamily: Ommatostrephinae 



Genus: OMMATOSTREPHES d'Orbigny 



Ommatostrephes sagittatus (Lamarck) 



f 



Type : Lamarck cites "Habite I'ocean europeen et americain. 

 Collect, du Mus." (Paris Museum d'Histoire Naturelle). 



Distribution : This is one of the rapid and powerful swim- 

 mers of the open sea, known as "sea-arrows." It is widely dis- 

 tributed in the Mediterranean Sea, the Atlantic coasts of Europe 

 northward to Denmark, northern Norway, also the ocean shores 

 of Greenland; southward it is known from the Hispanic coast, 

 the Canary Islands, and off northwest Africa. The Atlantic Ocean 

 distribution of this species appears to coincide with the paths of 

 the Eastern Current of the Gulf Stream and of the Rennell Cur- 

 rent. 



Material examined: One Rhynchoteuthis-stage (Chun), 

 taken in 250 fathoms, off Fuerte Ventura, Canary Islands, Puerto 

 Cabras, bearing 270° true seven miles distant, February 18, 1932, 



Remarks : This specimen, which has a body length of 4.5 milli- 

 meters in the median dorsal line, is in about the same stage of 

 development as that shown by Mr. Naef (1923) , in text figure 211 

 of a specimen he had from Naples plankton. The caudal fins of 

 the present specimen are subterminal, slightly deformed. Naef's 

 excellent study of both the larval and adult forms of this species 

 and Dr. Chun's study of the Rhynchoteuthis form render addi- 

 tional description of this larval squid unnecessary.
