manners. Professor Rymer Jones, in the last edition of his 

 Animal Kingdom, says, that "our knowledge of these 

 animals has been until recently very limited ;" and he adds, 

 " the zootomist who should enjoy fcivourable opportunities 

 of inspecting the larger species in a fresh state, could hardly 

 make a more valuable contribution to our science than by 

 giving an account of the organisation of these interesting 

 animals." My opportunities of observing the larger species 

 have been null ; but having dredged uj) many of the smaller 

 species off Tenby and Caldy, I studied those with great 

 eagerness ; and although my observations had, for the most 

 part, already been included in the more elaborate investi- 

 gations of Milne Edwards and Dr 'Williams, I have yet 

 something new to offer, little though it be. 



No one, I believe, has yet recorded the f<ict of the Tere- 

 bella multiplying itself by the process of gemmation, which 

 is known to occur in the case of some other AnneKds — such 

 as the Ndis (Plate IV., fig. 3), the Syllis, and the Myriana, 

 and of which the reader will find all the details in the works 

 cited below.* When the animal reproduces by this budding- 

 process, it begins to form a second head near the extremity 

 of its body. After this head, other segments are in turn 

 developed, the tail, or final segment, being the identical tail 

 of the mother, but pushed forward by the young segments, 

 and now belonging to the child, and only vicariously to the 

 mother. In this state we have two worms and one tail. It
