A very curious unrecorded species, now first introduced 

 from the Cape of Good Hope. The masterly description 

 is by Mr. Brown, who has so far modified the character of 

 the genus with respect to that defined by himself in his 

 illustration of the Natural Order, in the ' Memoirs of the 

 Wernerian Natural History Society,'^ as to fit it for the 

 reception of the species before us ; which he considers too 

 miturally allied to the East Indian group he had originally 

 allotted toCEROPEGiA to be separated.
