The figure given by Brebisson of Cl. ilcconnn is not ;i 

 one, but at the same time it is snllirient ly irood to recognise 

 its identity with Cl. Di'lpuntvi (KK-lis) \Volle. AVe have ^iven 

 :i '-npy of Brebisson's figures (PI. XX^II, ii^-s. 7, S) and of two 

 of Delponte's figures (PI. XXV, figs. 1, '2) for jMirposes of 

 comparison with each other and with our own (PI. XXV, 

 fig. 3. 



('/. ili'citi'/i in is a very rare British species, altliough it is 

 l'rr<|iient in tropieal and subtropical countries. It; has a 

 slight though variable curvature, and it also varies much in 

 relative length and breadth.
