Implantation of the spermatophores is accom- 

 plished by means of the "hectocotylized" arm of 

 the male, which is the left undermost arm and 

 which is so modified as to perform the functions of 

 reproduction. 



5. The number of eggs contained in the an- 

 chored capsules of a single laying is about ten 

 thousand. 



6. The range and the rapidity of color changes 

 possessed by the squid are greater than those pos- 

 sessed by any other creature in the sea. It is shown 

 that its chameleon-like capacity is not primarily 

 concerned with concealment, but is, in some way 

 not understood, related with the seasonal mating 

 activities of both sexes. For the real purpose of 

 rendering itself invisible to its enemies, the squid 

 relies on its ink bag. 



7. There is strong reason to believe that al- 

 though the outstanding function of the ink bag is 

 to produce a masking cloud, or "smoke screen" for 

 the confusion of its foes, it has the secondary prop- 

 erty of functioning as a scent-producing gland — 

 thus enabling this gregarious creature better to 

 follow the trail or trace the whereabouts of its 

 swiftly traveling fellows.
