BATHYPELAGIC SQUID BATHYTEUTHIS 65 



Comparison of club lenoi:;h vs. mantle length indicates that the clubs 

 of hacidljera tend to be about 25-30% longer than those of dbyssicola 

 of the same size (tig. 8) . 



Tlie proportion of club length to tentacle length overlaps in the two 

 species but the plot for hacidifera occurs in the upper range of values 

 of ahyssicola (fig. 9). A specimen of hdcidifera of 15 mm ML would 

 have a tentacle length of about 20 mm and a club length of 4.5 mm, 

 while a specimen of dbyssicola with the same tentacle length would have 

 a mantle length of 19 mm and a club length of 3.5 mm.
