 Antennce setaceous, from 2 to 4. Body oval,

By Mr. T. W. Simmons's indefatigable industn,', iu 

 laudably searching into the knowledge of the natural pro- 

 ductions of Great Britain, whenever he had an opportunity, 

 we are enabled to figure this species. He observed thi& 

 strange-looking animal entangled in the nets off Dysart, 

 near Inch-Keith. 



It has an appearance that may often cause one to mistake 

 the head for the tail : see the upper figure. In the middle 

 figure it seems like a tumbler, or master of attitudes j in the 

 lower figure it appears to be at rest. 



The eggs are red, and adhere to the under side of the 

 largest segment of the body.
