Proceedings of the Royal Irish Academy. 



In the subjoined Table I give a series of measurements in millimetres 

 alluded to in the text. All these were taken from specimens contained in 

 the Irish National Museum, except those from Walthamstow and Clapton, 

 which are in the British Museum (Nat. Hist.). Dr. Smith Woodward was 

 good enough to allow me to measure the latter.
