to follow up the suggestion here made. Further careful 

 observation of this form could hardly fail to be productive of 

 most valuable results. There is probably no point in 

 Zoology bearing on which there has been less reliable 

 information accumulated, or on which information is more 

 desirable than the reproduction and life history of the 

 members of the Class Rhizopoda. 



Examples of both species, D. radiata and D. erecta, occur 

 in the locality named, but they merge so insensibly into 

 each other that it seems to me impossible to define the 

 limits of either. 



Technitella legumen, Norman. 



A few specimens of this very curious little form, the test 

 of which is entirely built up of sponge spicules, have been 

 found in material from the estuary of the Dee. 



Psammosphoera fusca, Schultze. 



The specimens of this form are small and rare in our 

 district, and hardly typical. 



Hyperammina elongata, Brady. 



Messrs. Balkwill and Wright (Recent Dublin Foraminifera) 

 say of this : — " Large and very abundant at Lambay, muddy 

 bottom ; also met with in other places in Irish Sea." The 

 few specimens I have seen are small and weak. 



Haliphysema Uunanowiczii, Bowerbank. 



Typical examples of this remarkable form are frequently 

 to be found in the same prolific corner of Colwyn Bay, near 

 to the Little Ormes Head, already quoted as the special 

 habitat of other rare species. I have found it there on 

 several different occasions, always fixed upon the polypidom 

 of Cellularia avicularia, 



Reophax spp., Montfort. 



R, fusiformis and R. scorpiurus, are rare among those
