tnuities of studying further material from various sources. At the 

 British Museum there are specimens of a Sapium, labelled ' Peru, Herb. 

 Pavon, Sapium Aucuparium sp. nov., Ruiz et Pavon, de Iluayaquil/ 

 and I think there is no doubt that they are the same as Excoecaria 

 higlandulosa, /3 Pavoniana, Muell.-Arg., {Sapium Pavonianum, Huber). 

 Thanks to the Keeper of the Botanical Department of the British 

 Museum and to the Directorate of the Royal Botanic Garden, Berlin, 

 Kew now possesses complete drawings of two sheets of specimens of 

 Herb. Pavon, and Nos, 1925 and 1935 of Herb. Preuss ; also fragments 

 of 1925 and 1935 ; also several barren specimens from TTerb. Lehmann. 

 Both Lehmann and Preuss state that this tree vields the Caucho 

 andullo bianco or Cauchillo, a rubber not of the best quality. All the 

 specimens here referred to this species are from slight elevations iu 

 the coast region, and I doubt very much now whether the leaf from 

 Moyobamba, Peru, mentioned in the letterpress to t. 2757, belongs to 

 S. utile, Preuss. — W. Botting Hemsley.
