tylus by the discoverer, Cuvier. Therefore, in 

 consequence, the correspondingly modified arms of 

 other cephalopods have come to be called "hecto- 

 cotylized." 



However, compared with the complexity that 

 occurs in the reproductive modifications and 

 methods of the forementioned argonauts, the case 

 of Loligo may be called quite simple. The tentacu- 

 lar arms of both sexes are completely retractile 

 and usually are extended only for the purpose of 

 prehension, such as seizing prey. The left ventral 

 of these arms in the male is swollen at the tip and 

 adapted for transferring the spermatophore. This 

 capsule is placed during coitus within the mantle 

 cavity but close to the region of the lower lobes of 

 the buccal membrane. Soon after mating, the fe- 

 male lays her eggs. When the eggs are deposited, 

 the sperm packet is ruptured, releasing a cloud of 

 spermatozoa to effect fertilization. The club ends 

 of the tentacular arms are furnished with four 

 rows of sucker-cups; the stationary, or sessile arms 

 are furnished with but two rows. In the last-named 

 appendages, the cups line the whole length of the 

 inside of the arm, each cup being pedunculated, or 

 set on a short stalk. A slight fringe, or so-called
