growth. This presents another striking difference 

 from anything that has been seen amongst the 

 Nautili, but at once reminds us of the investing 

 Corallines. These new cells have either been 

 soft germs, which have escaped from the interior, 

 and fixed themselves on the backs of their 

 parents, or they have been produced by that 

 process of budding, or gemmiparous generation, 

 so common amongst the lowest animals. 



Fig. 30 represents an elegant species of Poly- 

 stomella, allied to P. crispa. In this instance, 

 instead of the segments of the animal being 

 connected by one chain of necks passing through 

 the septa, there are a considerable number, which, 

 when viewed in front of the anterior cell, are 

 seen, in this genus, to be arranged so as to 

 represent two sides of a triangle .•'•. . These 

 apertures are situated close to the point of junc- 

 tion, between the septa and the lateral parietes 

 of the cell * 



Figs. 31 and 32 represent young and old 

 forms belonging to the allied genus Peneroplis, 

 where, instead of the perforations being arranged 



* The plate gives a less faithful representation of this animal, 

 viewed as a transparent object, than I could have wished.
