This fine species, of which only one example has yet 

 been seen, was strong and active ; survived being pressed 

 flat under cover-slip till the details of the rami were studied ; 

 crept about vigorously afterwards, and lived for several days. 

 It did not readily extend its discs while under observa- 

 tion, so that the details of the wreaths w^re not fully made 

 out. It carried a large brown egg.
