The King Edward Hotel Woods Colony. 



This piece of woodland also occupies a hill-top, situated across the 

 road from the King Edward Hotel, and lying to the east of the Benmore 

 woods about half a mile distant. It is a conical hill of some 3 or 4 

 acres, densely wooded, but the wood more open and rather dryer 

 than that at Benmore. Not much limestone is seen in place until 

 near the top of the hill, where low exposures as well as numerous loose 

 blocks are encountered. The limestone is the more impure kind, 

 weathering into blocks of all sizes and producing a great quantity of 

 loose stone in small pieces. The hill is not very high and the elevation 

 is about 2,000 feet above sea level. Roadside cuttings have been 

 made along the west side of the woods, where a certain amount of 

 talus from the hill makes an accumulation of loose small stones that 

 are good collecting places. Where the woods is not stony, a layer of 

 leaves of some inches thick covers the slopes of the hills, and in this 

 many living Pleurodonts were found. Along the road to the west 

 many were obtained crawling in the gutters after rains. The woods 

 is isolated by roads on two sides and open pastures on the other sides 

 as well as across the roads. It is practically virgin forest. 



The Cedar Hill Woods Colony. 



This rather small woods occupies the northwest slope of a hill on the 

 estate called Cedar Hill or Cedar Grove, and extends from a road at 

 the foot of the hill to the top, where it is bounded by open pasture land, 

 as it is on the southwest side, while cultivated ground bounds it to the 

 northeast. Across the road is open pasture land, extending to Ben- 

 more woods, and about a quarter mile to the northeast is the woods at 

 King Edward Hotel. This is a very dense jungly woods, exceedingly 

 rocky; the pure limestone cropping out on the entire hillside, and 

 extending to the hill-top, which is covered by loose blocks of limestone. 

 It is evidently an undisturbed piece of the virgin forest, as can be seen 

 by the flora as well as by the species of mollusca obtained here. The 

 limestone being well exposed and, as usual, much honeycombed by 

 holes, the collecting was good. "Dead" shells were especially plen- 

 tiful. 



The Bloomfilld Colony. 



The Bloomfield estate lies to the southwest of Mandeville Court 

 House, and the collections were made along a roadside cut and cliff 

 for perhaps a quarter mile on the Lower Santa Cruz Road, including, 

 too, the strip of woods at the top of the cliff. This is much disturbed,
