Introduction of Lobsters. 



The desirability of introducing the European lobster {Homarus 

 vulgaris) into these seas has been before the promoters of this 

 station since its inception. It has been stated that there is no 

 need to introduce this crustacean, seeing that the marine cray- 

 fish (Palinurus) is so common, and is such an excellent article 

 of food. While these facts are quite admitted, yet it is the case 

 that the lobster has a much greater commercial value than the 

 crayfish, and if once acclimatised in these waters would prove 

 a very valuable addition to the wealth of our fisheries. Again, 

 it has been objected that the chances of establishing a species 

 which undergoes various metamorphoses in its early stages, 

 when it passes through several free-swimming stages, when it 

 cannot well be handled, are very great. But the hatching and 

 rearing of lobsters, both H. vulgaris and H. americanus, have
