NO. 2 FRASER : SCIENTIFIC WORK, VELERO III, EASTERN PACIFIC 165 



Punta Pifias is at the tip of a slender, southerly projecting peninsula 

 that serves as a perfect protection for Bahia Pifias, a small bay, 1% miles 

 across at the entrance, extending northward for 2% miles, to form an 

 excellent, safe anchorage. Here there are shore stations on rocks and in 

 coral masses and dredging stations in 3 to 35 fathoms, in sand, mud, rock, 

 shell, and coralline. 



After Bahia Pifias the coast line continues the same general trend, 

 25 miles, to the Panama-Colombia boundary, and another 28 miles to 

 Cape Marzo, at the entrance to Octavia Bay. Before reaching the cape, 

 however, there is a definite indentation facing the northwest, Humboldt 

 Bay.

Cape Marzo is bold and rocky, with a reef and detached rocks ex- 

 tending 3 miles south of it. It forms the western extremity of Octavia 

 Bay, the coast of which extends northward, eastward, and southeastward 

 to Point Cruces, 15 miles from Cape Marzo. The 2-mile northward ex- 

 tension of the bay is well sheltered. Collecting on the shingle and in the 

 coral masses of the extending peninsula and dredging in 30 to 75 fathoms 

 were the only activities here. In the shallower hauls there were sand and 

 gravel, but in the deep ones only gravel and mud. 



Point Cruces is much similar to Cape Marzo, at the tip of a southerly 

 extending peninsula, with rocky islets offshore. It forms the western 

 boundary of the Gulf of Cupica, extending 22 miles to Solano Point, but 

 receding behind these points to form Cupica Bay to the north and Solano 

 Bay to the south. 



Cupica Bay is 5% miles wide and extends northward 3^ miles. The 

 peninsula to the west of it serves as an excellent shelter, and the anchorage 

 is a safe one. There are one shore station here, on the inside of the rocky 

 point, and one electric light station. 



From Solano Point the coast line extends southward for 7 miles, to 

 pass into another bight, extending 36 miles to Alusea Point. Fourteen 

 miles from the north end of this bight there is a small fiordlike inlet, 

 Port Utria, receding northward 3 miles, almost parallel to the coast. At 

 the entrance it is but y 4 mile wide, but farther in it may be twice that. 

 It is separated to the westward from the open sea by a high, narrow 

 peninsula, with two islets and some isolated rocks off its extremity. It 

 forms a safe, well-protected anchorage. The shores of the peninsula and
