hesitation, to colour them red. Eespecting Folger and Mar- 

 shall Islands, which lie some way east of the Marianas, I can 

 find out nothing, excepting that they are probably low. Kru- 

 senstern says this of Marshall Island ; and Folger Island is 

 written with small letters in D'Urvi]le's chart ; uncoloured. 



Bonin or Arzobispo Group. — Peel Island has been ex- 

 amined by Captain Beechey, to whose kindness I am much 

 indebted for giving me information regarding it : 'at Port 

 Lloyd there is a great deal of coral ; and the inner harbour is 

 entirely formed by coral-reefs, which extend outside the port 

 along the coast.' Captain Beechey, in another part of his letter 

 to me, alludes to the reefs fringing the island in all directions ; 

 but at the same time it must be observed that the surf washes 

 the volcanic rocks of the coast in the greater part of its cir- 

 cumference. This island has certainly been elevated at least 

 50 feet within the recent period (see Journal of Geolog. Soc. 

 1855, p. 532). I do not know whether the other islands of 

 the archipelago are fringed ; I have coloured Peel island red. 

 • — Grampus Island, to the eastward, does not appear (Meare's 

 Voyage, p. 95) to have any reefs, nor does Rosario Island 

 (from Lutke's chart), which lies to the westward. Eespect- 

 ing the few other islands in this part of the sea, namely 

 the Sulphur Islands, with an active volcano, and those lying 

 between Bonin and Japan (situated near the extreme limit 

 in latitude at which reefs can grow), I have not been able 

 to find any clear account. 



West End of New Guinea. — Port Dory : from the 

 charts in the Voyage of the Coquille, it would appear that 

 the coast in this part is fringed by coral-reefs ; M. Lesson, 

 however, remarks that the corals are sickly ; coloured red. 

 — Waigiou : a considerable portion of the northern shore of 

 these islands are seen in the charts (on a large scale) in Frey- 

 cinet's Atlas to be fringed by coral-reefs. Forrest (p. 21, 

 Voyage to New Guinea) alludes to the coral-reefs lining the 

 heads of Piapis Bay ; and Horsburgh (vol. ii. p. 599, 4th
