244 THE JOURNAL OF HOT ANY 



I suggest that the error arose because it was recognised that 

 anomala was specifically distinct from gregaria (which was accepted 

 without question as lingua ), and, as it manifestly could not he a form 

 of cordigera or longipetala, it was natural to consider it a variety of 

 occultata, the only other Serapias in the locality. This opinion was 

 no doubt confirmed by the fact that anomala appears to have two 

 parallel calli, which is the case in occultata. This, however, is not 

 really the case. The callus in anomala is of the same shape as 

 in lingua, hut the colouring is different. In lingua the whole 

 callus is blackish red and glossy; in anomala its main hulk is yellow, 

 of the same colour as the base of the lip, from which the eye does not 

 easily distinguish it, and only the ridges on each side of the furrow 

 are dark red and glossy, giving the impression, by an optical illusion, 

 of two separate calli. The calli of parcijlora are quite different in 

 shape.
