as amusing as an Armadillo — a species or two of Arcturus, and 

 allied kinds, conclude with mention of — 



Gammarus locusta. — This crustacean has lived generation 

 after generation in my aquaria. An interesting trait in its 

 nature is the care the parents take of their young. Male and 

 female associate together, and pair off all their lives. The female 

 is especially fond of her husband, and carries him about 

 wherever she goes, until her eggs are hatched, when they 

 both look after the young. The newly hatched ones do not 

 essentially differ from the adult form, as do other Crustacea, 

 unless they develop ere they leave the abdomen of the female. 

 Like Shrimps they grow rapidly. Mine are tamable creatures, 

 and come to a pointed stick or small quill as readily as the 

 Prawns do.
