Occasional Papers of the Museum of Zoology 17 



Station Cll. This includes four localities along the ridge 

 that skirts the coast of Hato. The cap of ancient limestone 

 becomes progressively thinner and the vegetation more sparse 

 towards the southeastern end, where the conditions approxi- 

 mate those of Seroe Boca (CIO). 



Clla. Scroc MarJ:ifa (11-L; L6S° 50.95', 12° 9.06'). This 

 lot is from the more barren end (50.1 meters) of the Hato 

 ridge. 



Cllh. North of Bonde Klip (11-M ; L68° 52.06', 12° 9.38'). 

 The southern slope of this portion of the ridge (59 meters) is 

 more heavily wooded than Clla. 



Cllc. Seroe Papaja (11-N; L68° 57.20', 12° 10.71'). The 

 dwarfed vegetation on the top of this ridge (62.6 meters) is 

 abundant, while the base of the low escarpment, and the 

 areas between the large, detached blocks of limestone, are 

 grown up with brush and trees and support a thriving mol- 

 luscan population. ]\Iost of the collection comes from these 

 more protected places. 



did. Near Landhuis Hato (11-0; L68° 57.92', 12° 10.95'). 

 The high northern escarpment of Seroe Spelonk (70.4 meters) 

 is excavated into spacious caves, with enormous stalactites 

 pendant from their roofs (fig. v-13). At Landhuis Hato, 

 one of the only permanent streams on the islands issues from 

 a cave. The nearly level terrane near the base of these cliffs 

 supports a luxuriant growth of brush, and the densest stands 

 of Cereus that I have ever seen. 



Station C12. Ronde Klip (12-?).^*^ This mesa is separated 

 from the nearby Hato ridge by a valley, in which the diabase 

 comes to the surface. It is almost encircled by a high escarp- 

 ment of the older limestone, which surmounts the steep, red- 

 dish slopes with diabase outcrops. 



Cl2a. Base of ivestern escarpment. (L68° 52.08', 12° 9.00'). 

 At the base of the limestone cliffs are thickets of brush and 

 clumps of larger trees. This is one of the richest habitats 

 in central Curasao.
