stone. The locality collected is at the base of these cliffs, where 

 the vegetation is as rich as in any portion of the windward 

 side (fig. iv-10). 



B3h. Kibrd di Montagne (H; L68° 16.29', 12° 12.01'). A 

 high saddle (about 100 meters) separates the main hill from 

 a narrow limestone ridge that extends in an easterly direction. 

 The pass itself is rather barren, although the vegetation is 

 much richer in the valleys at either side (fig. iv-9). 



Station B4. Weste^-n slope of Montagne (K; L68° 17.24', 

 12° 11.86').^® The valleys on the leeward slopes of Seroe 

 Largoe (Campo Santa Barbara) contain dense thickets of 

 brush, interspersed with clumps of larger trees. The station 

 is in one of the richer of these, and is perhaps the most heavily 

 wooded locality collected on the limestone of any of the islands. 

 The crotons attain a height of 2 meters, and form almost im- 

 passable thickets, except where the larger trees outshade them. 

 Most of the shells come from around the Guaiacum and 

 Bursera trees. 



Station B5. Porta SpaTio (M; L68° 16.68', 12° 14.06'). ^« 

 At the top of the low cliffs that form the northern border of 

 the broad plain of Campo Bolivia (0), the larger trees form 

 rather open groves, which are as extensive as any in the 

 islands. 



Station B6. Base of cliffs near Fontein (P; L68° 17.73' 

 12° 14.66'). The northern escarpment of Seroe Grita Kabai 

 (87 meters) is high and precipitous. At Fontein, a tiny rivu- 

 let, the only permanent stream on Bonaire, emerges from a 

 cave in the older limestone. The locality collected is at the 

 base of the cliffs just north of Fontein ; the reddish residual 

 deposit is especially prominent at this place. 



Station B7. Punta Blanco (R; L68° 12.67', 12° 10.25'). 

 Near the southeastern end of the main anticline, the recent 

 limestone, along the eastern shore of the island, is limited to a 

 comparatively narrow border. At Punta Blanco (21.5 

 meters), the inland edge of this formation presents low escarp-
