GULF OF MEXICO 



477 



mutilated by sharks was taken from the surface 

 of the Gulf Stream off the Florida Keys. The 

 specimen was measured by the author and es- 

 timated to be about 15 feet long when entire so 

 that the presence of the giant squid in these 

 waters is now confirmed. 



The nimiber of individual species of cephalopods 

 found in the Gulf of Mexico is rather difficult 

 to determine due to the previously mentioned 

 lack of records. However, the completed results 

 of the Oregon explorations will materially increase 

 our present knowledge of this interesting fauna. 

 The following list of species arranged in their 

 taxonomic order mcludes species which have been 

 taken from the plankton of the Gulf Stream off 

 Miami and as such should be found in the portion 

 of the Florida Current traversing the Gulf of 

 Mexico. Certain others have been reported thus 

 far only from the Lower Florida Keys. Both of 

 these groups are marked with asterisks, and only 

 those not so marked have been actually found in 

 the Gulf of Mexico proper. Many more records 

 could be added from the Caribbean area, but as the 

 presence of these species in the Gulf of Mexico 

 has not been proved they are not inclu 'ed in the 

 present list.
