FELIDU. 117 



apparently identical with the reef rock forming the boulder belt off Buri 

 Hura. There is evidence of a more general erosion at Felidu than in any 

 other group of the Maldives. 



There is a large faro with a wide rim on the eastern face of Felidu to the 

 south of Keadu; the chart indicates a depth of four fathoms in the lagoon. 

 Keadu and Felidu are two well-wooded islands; to the north on the eastern 

 face of Felidu, Tinadu and Alimata are the only islands on the outer faros. 

 The passes between the larger faros of the east face are usually divided by 

 long sand banks, leaving only narrow but deep passes on each side, judging 

 from the deep blue color of the central part of the pass. These bars are 

 well indicated on the chart ; the sand-bars awash are perhaps larger ; other- 

 wise no important change seems to have taken place on that part of the 

 east face of Felidu since 1836. Passing out of Felidu between two faros 

 halfway between Tinadu and Alimata we found the outer horns of the 

 faces of the pass distinctly marked by piles of angular boulders undercut, 

 pitted, and eroded. On the outer rims of the faros of the eastern face sand- 

 bars often took the place of the boulder belt, while to the north of the 

 pass above mentioned, the reef rock patches and shingle heaps continue 

 on parts of the outer edge of the reef flats and faros. Extensive patches of 

 corals also dot the outer rims of the faros. The northern passes of the 

 eastern face, as seen skirting the outer edge, stand out as well-marked, 

 inverted funnel-shaped entrances, with dark blue bands indicating the deep 

 parts of the channel. The outer beaches of Alimata are steep coral sand 

 beaches, with but few boulders on the outer edge of the reef flat. The 

 lagoons of the two large faros to the north of Alimata have depths of five 

 and seven fathoms. Digeri Island is situated just inside of the pass sepa- 

 rating these faros. 



While there are a great many passes leading into Felidu, yet no part of 

 its periphery is open. The widest passes are less than a mile, the majority 

 being narrow cuts of considerable depth, often more than twenty fathoms.
