MARINE CRUSTACEA IN CONFINEMENT. 57 



Shorter-limbed Hyas and Maia. The most remarkable trait of 

 the latter has been the fancy it has for sticking pieces of sea- 

 weed on the short spines which are beset all over its body and 

 limbs. 



For thirty-five years my aquaria have never been for long 

 without some representatives of the Prawns and Shrimps. I have 

 been specially interested in the former because of the marvellous 

 transparency of their bodies when in health. One which I had 

 more than thirty years ago, and which lived a long time — even 

 breeding — I called "Crystal," because she looked as though 

 made of glass. She was not the only one I have had breed. I 

 have kept sometimes as many as two hundred small larval Prawns 

 at one time.
