 Genera. 



1. Cueubalia. 



Body provided with a large proboscidiform exsertile sucker, with a 

 bunch (grappe) of ovaries at its base, lodged in a large single excavation 

 of a natatory anterior cordiform organ, receiving also the posterior, 

 which is also cordiform and hollowed 

 nto a cavity with a posterior and sub- 

 oval orifice. 



Example, Cuculalu* cordiformis, the 

 only species cited of the genus esta- 

 blished by MM. Quoy and Gaimard. 

 length, two lines. Differs from the 

 ther Diphyd(f, first, in having the 

 nucleus much less hidden and sunk in 

 ,he anterior natatory body, which has 

 moreover only one large cavity in which it is plunged ; secondly, in 

 having the oviferous production very short ; and, lastly, in the mode 

 of locomotion, for the animal always swims vertically. 



2. Cucullus. 



Body furnished with a great exsertile proboscidifonn sucker, with 

 a bunch of ovaries at its base, lodged in a deep excavation, the only 

 one in the anterior natatory 

 organ, in form of a hood, in 

 which the posterior is inserted

j-agonal, and pierced behind 



with a rounded terminal orifice.

3. Cymla (Nacelle). 



Body furnished with a large 



exsertile and proboscidiform 



ucker, having at its base a 



mass of ovariform organs, 



odged in the single and rather deep cavity of a naviform natatory 



51-gau, receiving and partially hiding the posterior natatory organ, 



which is sagittiform, pierced behind with a rounded orifice crowned 



with points, and hollowed on its free border by a longitudinal gutter.
