casts of Pectunculus were found in the roadway near a small 

 creek. The second night was spent at Escalantes and five hours 

 ride the next day took the party to Sabaneta. All the way from 

 Las Matas to Sabaneta is over the reddish gravels. 



On approaching Sabaneta (5 on map) one sees the level, 

 grassy savannahs. These, like those of Venezuela, have never 

 been cleared and are natural meadows. Near by the grass is 

 seen to be short and poor, although in the distance the plains 

 look very green. The savannahs are diversified by little knolls 

 rising from them, covered with bushes. These knolls have super- 

 ficially the appearance of morainal hills. The savannahs are of 

 different levels, in some cases this difference being approximately 

 fifty feet. Those of the savannahs which are close to streams 

 are deeply cut by dry arroyos and are left often standing as 

 blocks. The summits are grassy, but the slopes covered with 

 bushes. The town of Sabaneta is built on one of the large sa- 

 vannahs on the banks of the Rio Yaguajal and its altitude is ap- 

 proximately 325 feet. 



A day and a half were spent studying the bluffs along the 

 river at Sabaneta, but they were found to be unfossiliferous. 



A search was then undertaken to find Rompino, one of Hen- 

 eken's localities where more than sixty years ago he had collect- 

 ed fossils. This proved a difficult and very unsatisfactory quest, 

 as the present Rompino is a regional name. These regions are 

 quite common, their limits are indefinite, and their existence of- 

 ten indicated only by a pulperia (little village store) or a shack. 

 On crossing the end of the Samba Hills on the road from Guay- 

 ubin to Sabaneta a fossiliferous cut was observed in the roadside, 

 the fossils in place being of the Area ponderosa type, while fur- 

 ther along the road the large A rca patricia occurred loose, not 

 in situ. 



Martin Garcia (6 on the map) is not well placed on Gabb's 

 map, as it really lies to the North of the Sambas. However, it 

 is also a region. Beyond Martin Garcia on the main road just 

 north of the pulperia forming the center of Martin Garcia, the
