OCEAN GAEDENS ; 



An allied ispecies, P. squilla, is scarcely distin- 

 guishable from P. serratus ; but tlie handsome 

 scarlet- striped Prawn, JPardulus annuticornis^ about 

 the size of a Shrimp, is quite distinct, and would 

 make a valuable addition to the collection. The 

 Lobster Prawn, also, Athanas nilescens^ has like- 

 wise been tried. 



Some kinds of Crabs may be admitted, but not 

 many; for several are extremely voracious, and 

 would soon clear off all the naked Zoophytes and 

 most of the Molluscs. 



The Climbing Crab, JEurynome aspera^ is inte- 

 resting in a tank from his habits. His climbing is 

 as graceful and skilful as that of a monkey, and when 

 he has succeeded in perching himself upon the highest 

 object in the tank, he forms a picturesq^ue object. 



Crabs, like Prawns, are sea-scavengers, and the 

 kinds that do not attack living creatures as well as 

 dead are consequently useful in a tank. The great 

 Piddler Crab, 'Fortunm puher^ is remarkably hand- 

 some. He is clothed, in part, with a velvety brown 

 fur, and the bare places of his shell are of a shining 

 black. His eyes are marked with scarlet, and there 

 are a few touches of bright blue about the head. 

 K introduced, his proceedings should be carefully 

 watched.
