the germ cells arise from the choanoc3rtes, that these are the 

 essential sponge elements, and that the sponge may be 

 regarded as a colony of Choanoflagellate Protozoa. 



A general paper is given on the Phoronidea, in which the 

 attempt is made to associate Phoronis ovalis and Actinotrocha 

 branchiata as one species, to indicate the general relationships 

 of the adult and larval species of the group, to present the 

 essential features of development, metamorphosis and structure, 

 and to discuss the position of the group. 



The Tjme, at all events the North Tyne, and its tributary, 

 the Reed, are rich in larval lampreys, but the adults are seldom 

 seen. An account is given of the many larvae which have been 

 collected at Houxty and in the neighbourhood of Belhngham, 

 and attention is directed to the fact that although the larvae 

 are so common, the efforts made to secure or even to see the 

 adults have thus far been unsuccessful. 



It is acknowledged that at the hmits of distribution hydro - 

 graphical conditions are important, and it has been suggested 

 that in the area of distribution hydrographical and food con- 

 ditions are factors influencing migrations. As I stated in my 

 work on the " Migrations of Fish," I did not find it necessary 

 to introduce such considerations apart from ocean currents. A 

 short discussion of the question is given with a view to indicating 

 that these do not play an important part within the regions 

 of distribution. 



It is with sincere regret that vve record here the death, on
