rostral-like process, acutely pointed, and expanded into two lateral bulbous lobes. 

 Thorax wide. The interstitial neuration consists usually of stout transverse 

 nervures, occasionally forking or in a loose meshwork.

Description The type-specimen lies on the surface of one half of an ironstone 

 nodule, the counterpart being lost. It was obtained by Mr. Edward Charlesworth 

 from the Coal Measures of Scotland, but the locality and horizon are not known. 



The remains consist of portions of two pairs of wings, those of the left side 

 being most nearly complete. In no case is the apex of the wing or the inner 

 margin preserved. Lying in front of the wings are a pair of very large convex 

 lobes which Dr. Woodward regards as part of the prothorax, and in front of these 

 is a roughly quadrangular structure prolonged forward in the middle line into a 

 styliform process or rostrum. Woodward describes the latter as " the small head
