Irazu (Volcan de) : — The highest of the mountain peaks of Costa 

 Rica, an extinct volcano lying between the volcanoes Turrialba (on 

 the east) and Barba (on the west), with an elevation between 11,300 

 and 11,900 feet (the exact altitude is uncertain). 



It is a very large, flat-topped peak, sloping away gradually in all 

 directions, except to the north, where it is very precipitous. The 

 crater is immense, being at least half a mile in diameter, with several 

 deep openings in the floor, one of which extends to unknown depths. 

 It is entirely extinct and grass and stunted shrubbery grows over the 

 whole summit as well as inside the crater, wherever foothold can be 

 secured in the lava and ash composing the cone. The simple term 

 Irazu, when used by a collector means very little when we attempt to 

 exactly locate the place from which the specimen came, as it may be 

 anywhere between 5,000 and 10,000 feet above sea-level, on the 

 Pacific or Caribbean slope. However, most collectors have visited 

 the southern and western slopes of the volcano, and it is safe to assume 

 that most skins marked " Irazu' came from somewhere between 

 8,000 and 10,000 feet on that slope. The specimens which I col- 

 lected there were taken between those altitudes, unless otherwise 

 designated. 



Is/a de Uva : — An island in the harbor of Port Limon, containing 

 a light-house and quarantine-station. A colony of Gannets make their 

 home there. 



Jimenez : — A small town on the Old Line Railway, fifty-five miles 

 from Port Limon, and situated just at the edge of the foot-hills of the 

 Volcan de Turrialba. Towards the north much of the forest has been 

 cleared away for the planting of bananas for three or four miles back 

 from the railroad, but to the south or towards the volcano it is a solid 

 mass of virgin jungle, very rich in bird-life. Some of the rarest of the 

 Costa Rican birds have been taken here and some of them only here. 

 Senores Alfaro and Carranza ; Messrs. Underwood, Cherrie, Verrill, 

 and myself have collected at this place. 



Juan Vinas : — A thriving village situated on the plateau above the 

 railroad from Limon to San Jose, and twenty-eight miles from the 

 latter city. It lies on the eastern slope of the Volcan de Turrialba, 

 at an altitude of about 3,000 feet, with almost a sheer drop of a 

 thousand feet down into the gorge of the Rio Reventazon, on the other 

 side of which and a little lower down is the Indian village of Tucur- 

 riqui, where Arce collected the types of so many rare species. It was
