The only individual of this species preserved in the British Mus,,.,.. is not 

 more than one inch in length, although Leach states it to be one inch and a 

 half. It is a male specimen, having the anal styles very large and thick, but 

 it has only forty-one pairs of legs. I have never yet obtained Leach's species 

 alive.
