Although I have never seen a St.-Helena example of the 

 Mediterranean E. cJin/somelum, lean scarcely refuse it a place 

 in the present memoir, inasmuch as it was originally described 

 by Fabricius, in 1775 [vide the above diagnosis], from an ex- 

 ample, or examples, in the collection of Sir Joseph Banks, 

 which had been obtained in that island. Indeed, as it appears 

 to occur also at the Cape of Good Hope, and Fabricius himself 

 in 1792 cites as its habitat "in Cacto opuntio African," there 

 is no reason for doubting that the Banksian type was truly 

 (as stated) a St.-Helena one, though it is of course highly 

 probable that the species may have been introduced acciden- 

 tally into the island, perhaps along with plants of the Cactus 

 opunfia (or " prickly pear"), and so have become naturalized. 

 It is recorded likewise in the north of Africa ; but it has not 

 yet been observed in any of the Atlantic archipelagos.

 The present Opatrum^ like most of the allied species in the 



various Atlantic archipelagos, appears to abound in St. Helena, 



where it was taken by the late Mr. Bewicke in 1860, and
