A viscid gum, with an unpleasant odour, exudes from the wounded

58. “ Birros,” used on the Amazon in making cushion-lace. Seven 
of them are of the fruit of the Tucumá palm, the other five of the fruit 
of the Mucajé; four of the latter being polished by rubbing them with 
a stone. Breast-pins are sometimes made of the fruit of the Mucajá, 
but I have not yet been able to get one. 
59. Fruit of the Atta (Anona sp.). Santarem, cultivated. This 
fruit is purple and glaucous when ripe; it has shrunk much by the 
drying up of the pulp, which is the edible part, and has the taste of a 
scarcely ripe Orleans-plum. : 
60. Fruit of a Sterculiacea, Herb. 837. Large tree, with the aspect 
of the Sycamore, frequent near Santarem. The follicles are of the 
purest scarlet when just burst open, but in drying they change to dull 
crimson. ae

Proteacee produce many interesting species. On the first sand-plain 
the road passes over to the north of the Moore river, I found in abun- 
dance a fine new Petrophila, nearer P. Shuttleworthii than any species 
described, but the leaves are more divided, the divisions narrower, the 
heads of flowers larger, and the cones shorter. 
A new Petrophila, near P. biloba in habit, but with larger leaves, 
which are thickly covered with long silvery hairs, grows on a low iron- 
stone hill close to Mr. Davidson’s station on the left bank of the Moore 
river; the flowers of this species were past when I found the plant, 
but the seed-vessels are very different from P. biloba. Another new 
Petrophila, with curiously pinnate leaves and small yellow flowers, 
grows abundantly on ironstone hills to the north of Dundaragan ; this 
plant has but little resemblance, either in its flowers or foliage, to any 
described species. Another new species, belonging to Mr. Brown's 
second division of the genus, with filiform divided rm on
