This exceedingly rare species is probably represented in the Musea 
by two specimens only, one, being the type-specimen of Fabricius, at 
Copenhagen, the other, that of Herbst, at Berlin! As Dr. de Man in- 
formed me, it appears very doubtful, whether Alcock’s specimens really 
1) The specimen had lost all the ambulatory legs, except the anterior pair. The lost pairs, — 
however, are all regenerating and budding out again. This indicates a great tenacity of life and 
a regenerative power which appears most enviable to everybody, especially in the war times of 
these days! The animal must have emerged out of some animated scrimmage in a deplorable 
state and, though its comparative helplessness must have rendered it an easy prey to any pur- 
suer, it has managed up to the time of its caught to escape all dangers,
