ADDITIONS AND CORRECTIONS

Page 5 and subsequent pages. _For_ Ipomea _read_ Ipomœa.

Page 68. _For_ Hippomanes _read_ Hippomane.

Page 68. _For_ Conocarpus erecta _read_ Conocarpus erectus.

Page 122. Sir W. Buller includes the fruits of the Puriri tree (Vitex littoralis, according to Kirk) amongst the food of the New Zealand fruit-pigeons.

Page 177. _For_ Entata, in the head-line, _read_ Entada.

Page 266. The fruits of Oncocarpus vitiensis have been found in the crop of a Fijian fruit-pigeon (Carpophaga latrans). _See_ Hemsley’s _Bot. Chall. Exped._, Introd., 46, and iv. 308; also Newton’s _Dictionary of Birds_, p. 724.

Page 368. Sernander (p. 185) observes that the fruits of Naias marina have little or no floating power.

Page 416. For the first eight lines read as follows:—“Of these, 22 occur in Continental regions on both sides of the Pacific; 12 are found in the Old World alone; one is peculiarly American, and two are confined to the Australian and Polynesian regions. A few of these can be regarded as exclusively American in their origin, though the bulk of them hail evidently in the first place from the Old World. But from the circumstance that all or most of the other species of the genus concerned are confined to America, it may legitimately be inferred that Waltheria americana, Ageratum conyzoides, and Physalis angulata are American-born species. Teucrium inflatum is a peculiar instance of an American weed collected in Polynesia before apparently it had been recorded from the Old World.”

Page 438. _For_ Conocarpus erecta _read_ Conocarpus erectus.

Page 417. Add after Cardiospermum halicacabum.... “Its seeds, as my experiments show, possess little or no capacity for dispersal by currents, since they sink at once or within a few days, even after drying for months.”

Page 508. Amongst my Solomon Island collections identified at Kew were the fruits of a species of Litsea from the crop of a fruit-pigeon (Hemsley’s _Bot. Chall. Exped._, IV. 295.)
