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

 "the zootomist who should enjoy favourable oppor- 

 tunities 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 hav- 

 ing dredged up 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 investigations of 

 Milne Edwards and Dr AVilliams, I have yet something 

 new to offer, little though it be. 



No one, I believe, has yet recorded the fact of the 

 Terebella multiplying itself by the process of gemma- 

 tion, which is known to occur in the case of some other 

 Annelids — such as the Nais (Plate IV., fig. 3), the 

 Syllis^ and the Myriana, and of which the reader will 

 find all the details in the accessible 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
