236 APPENDIX. 



investigated with so much success the Natural History of the 

 Philippines, informs me that a length of about three miles of 

 the shore northward of Point St. Jago is fringed by a reef ; as 

 are (Horsburgh, vol. ii. p. 437) the Three Friars off Silanguin 

 Bay. Between Point Capones and Playa Honda, the coast is 

 * lined by a coral-reef, stretching out nearly a mile in some 

 places' (Horsburgh) ; and Mr. Cuming visited some fringing- 

 reefs on other parts of the coast, namely, near Puebla, Iba, and 

 Mansinglor. In the neighbourhood of Solon-solon Bay, the 

 shore is lined (Horsburgh, vol.ii. p. 439) by coral-reefs, stretch- 

 ing out a great way : there are also reefs about the islets off 

 Solamague ; and as I am informed by Mr. Cuming, near St. 

 Catalina, and a little north of it. The same gentleman informs 

 me that there are reefs on the S.E. point of this island in front 

 of Samar, extending from Malalabon to Bulusan. These 

 appear to be the principal fringing-reefs on the coasts of 

 Luzon ; and they have all been coloured red. Mr. Cuming 

 informs me that none of them have deep water within ; al- 

 though it appears from Horsburgh that some few extend to a 

 considerable distance from the land. Within the Phillippine 

 Archipelago, the shores of the islands do not appear to be 

 commonly fringed, with the exception of the S. shore of Mas- 

 bate, and nearly the whole of JBoJiol ; which are both coloured 

 red. On the S. shore of Magindanao, Bunwoot Island is sur- 

 rounded (according to Forrest, Voyage, p. 253) by a ccral- 

 reef, which in the chart appears one of the fringing class. 

 With respect to the eastern coasts of the archipelago, I have 

 not been able to obtain any account. Prof. Semper has re- 

 cently published a notice (Zeitschr. f. Wissensch. Zoologie, Bd. 

 xiii. 1863, p. 558) respecting the coral-reefs of this archi- 

 pelago. It appears that some of them come under the class 

 of barrier-reefs ; but as I have not seen a chart on a large 

 scale, and know nothing about the depth of the water outside 

 the reefs, nor about the slope of the encircled land, I cannot 

 judge whether they properly come under the barrier class.
