OM THE SHETLAND FORAMINIFERA.

of the Somersetshire Archaeological and Natural History Society,' vol. xiii. 

 1865-66. There are also some forms of Lagena, Cristellaria, Uvigerina, and 

 Bigenerina, which seem sufficiently distinct from previously recorded British 

 ones to be described under separate names ; but I believe in no other order 

 is there so much difficulty in denning the limits of species and varieties, and 

 consequently so much danger of confusion in nomenclature. A more com- 

 plete investigation of the dredgings will, I have no doubt, afford additional 

 novelties. 



In the list and remarks appended to my former Report (1867), I endea- 

 voured to give as complete a view of the Shetland Foraminifera as our pre- 

 sent knowledge permitted, so that a comparison can be made of their relation 

 to those of the whole kingdom and of some neighbouring countries.
