This species was admitted into the 'Monograph of the 

 British Ostracoda ' on the occurrence of a single specimen in 

 shell-sand from Sutherlandshire. We have found it sparingly 

 in most of our gatherings from the Connemara district ; but it 

 would appear to reach its finest development in the Arctic 

 seas. (See Ann. & Mag. Nat. Hist. loc. cit.)

* Budle Bay is a large expanse of shallow water which at low tide 

 recedes so as to leave a muddy fiat, through which a small stream finds its 

 way to the sea. The situation is, therefore, essentially similar to that at 

 Westport, whei-e C. yihhosa was first found. — G. S. B.
