Our figure of this species was taken from Dr. Leach’s 
type in the British Museum (No. 1,002). It is unfortu- 
nately in very bad condition, having been pinned whilst 
in a soft state, so that the sides of the body have curved 
downwards, and our figure consequently represents the 
animal as having its lateral margin much too continuous,
