small and heavily covered with lichens. Low thickets of Opun- 

 tia Helleri occur along the tops of the cliffs and for some distance 

 back from them, and l^ereus nesiticus is to be found in several iso- 

 lated spots on the island. The most common bushes are those 

 of Cordia lutea, Croton Scouleri, Lantana pcduncularis, and 

 Waltheria reticulata forma Andersonii. A few grasses, sedges, 

 and other herl)aceous plants have been reported from this island, 

 but as our party visited it during the dry season in September, 

 none of these were found. 



Wenman Island. 



Witli the exception of Culpepper, Wenman is the most north- 

 ern island of the group. It is nothing more than an immense 

 rock, about a mile in diameter, which lies seventy six miles north- 

 west of Abingdon Island. The main island is surrounded by 

 perpendicular cliffs on all sides but the north where they are 

 somewhat broken doAVTi so that a landing can be effected and the 

 upper part reached. In many places the cliffs are several hun- 

 dred feet high, and some of them reach practically to the highest 

 part which probably has an elevation of about 800 ft. There is 

 a smaller island, to the north of the main one, and separated 

 from it by a narrow channel. This, however, was not visited by 

 our party. The channel between the islands is comparatively 

 shallow and it is likely that an anchorage could be made here. 

 It was not attempted by our party. 



We were unable to remain on this island for more than a few 

 hours in consequence of this the higher parts were not visited, 

 botanical collecting being confined to a shelf about 250 ft. above 

 sea level. The remainder of the island rises several hundred 

 feet higher. 



The only trees found on the island were those of Erythrina 

 velutina, a small grove of which occurs on the northeast side. 

 Bushes of Croton Scouleri var. brevifolius occur in dense thick- 

 ets and some of the specimens are several feet high approaching 

 the size of small trees. Low thickets of Opuntia Helleri are to 

 be found along the tops of the cliffs and hanging over the sides. 

 Ipomoea Kinbergi occurs commonly on trees. Other plants 

 found rather abundantly are : Scalesia Snodgrassi, and Telanth- 

 era Helleri var. obtusior. A few feras were seen growing in inac- 

 cessable places on the sides of the cliffs. By shooting into a
