172 ALLAN HANCOCK PACIFIC EXPEDITIONS VOL.1 



PLATE 76 



Fig. 161 View of the volcano Viejo or Chinandega, elevation over 5,000 feet, 

 located 17 miles from the city of Corinto, Nicaragua. The fringe of 

 mangroves is characteristic of the Central American shore line of Guate- 

 mala, Nicaragua, and San Salvador. 



Fig. 162 Port Parker, Costa Rica, presents a barren aspect in the dry season. A 

 further touch of desolation is added by the black patches which repre- 

 sent burned areas. Numerous brush fires were raging at the time of 

 the visit of the Hancock Expedition of 1939. 



Fig. 163 Port Parker, Costa Rica, located well within the zone of Papagayos, or 

 windstorms. Velero III scientists worked in the lee of the small island, 

 which is one of a series of stacks joined to the north shore of the bay. 



PLATE 77 



Fig. 164 The beach at Gulf of Dulce, Costa Rica, showing lava reefs which 

 make surf landing perilous. The dense jungle contains a few trees of 

 notable height. Chart 77, p. 407. 



Fig. 165 Expedition members shown accoutered for field work in photography, 

 mammalogy, herpetology, and botany, and marine zoologists already at 

 work on the volcanic rock shingle which juts into the Gulf of Dulce, 

 Costa Rica, at Matapalo Head.

 Costa Rica. (Photograph by Wm. R. Taylor.) 



Fig. 167 Precipitous shore of Cocos Island, Costa Rica. The island affords but 

 two landing places, Chatham Bay and Wafer Bay. Except for the 

 water courses, which are the natural highways throughout the island, 

 the interior is difficult of access. Chart 78, p. 408. 



PLATE 79 



Fig. 168 Fresh-water stream at Wafer Bay, Cocos Island, Costa Rica. It was 

 here that seine hauls were made for fishes occurring in the brackish 

 water resulting from the mixture of salt and fresh water with the in- 

 coming tide. Snacks of treasure-seekers are located to the right of the 

 picture. (Photograph by W. L. Schmitt.) 



Fig. 169 The surf at Chatham Bay, Cocos Island, Costa Rica, showing Nuez 

 Island in the right background. 



PLATE 80 



Fig. 170 Nuez Island, a satellite of larger Cocos Island, Costa Rica. Both are 

 covered with dense tropical vegetation of a brilliant green color. The 

 picture is taken from the deck of Velero III anchored in Chatham Bay. 



Fig. 171 Estuary at Puerto Culebra, Costa Rica, showing punt used to negotiate 

 the narrow channels, often overgrown with mangrove thickets. Chart 

 76, p. 407. 



PLATE 81 



Fig. 172 Puerto Culebra, Costa Rica, seen from behind a dense growth of colum- 

 nar cacti. 



Fig. 173 Skiff among coral heads exposed at an especially low tide on one of 

 the islands of the Secas group, Panama, a favorite collecting ground 

 for Velero III parties. Chart 79, p. 408.
