of which a specimen is exhibited, occurs on the British coasts and Table-case 

 ranges from Greenland to Chile and Japan. A coloured drawing ^°- ^•

 which are abundant in many rocks of Palaeozoic age, should bo 

 referred to this division.

 thoracic limbs carry exopodites and a double series of plate-like gills.
