16 W. J. CAIRD Zoophytes. 



present divided, but I should not be at all surprised if it should be 

 proved that when these shrimps develop to their full growth they form a 

 considerable item in the list of foods suitable for fish sustenance. 



Another of the Crustacea I would mention is caprella. There are 

 two forms I have found on Antennularia, viz , the smooth and the spiny. 

 They clasp the stem with the three pairs of posterior claws, and the head 

 and fore limbs are bent back away from the stem in search of food. 

 What I would like to direct your attention to, if you should follow these 

 up, is the two pairs of breathing apparatus attached to the sides of the 

 body. This departure from the true crustacean type is worthy of all 

 due consideration. 



Numerous varieties of minute encrusting seaweed are also to be 

 seen; but I am afraid I have already trespassed too far on your for- 

 bearance. Suffice it to say, that if any member of the Field Club should 

 take up this subject as a special study I will be most glad, for I think 

 some account of the hydroids found around the Buchan coasts would be 

 no mean addition to the Transactions of the Buchan Field Club.
