colour on the inside of the hind limbs does not extend so far 

 down to the hands" as in Sclater's specimen, "and the 

 whiskers offer only a faint trace of the whitish colour which 

 encircles the face" of vellerosus. Reinhardt says of his Mexi- 

 can specimen: "I have hitherto considered it a new species 

 and given it a provisional name"; but he appears to have 

 never published this provisional name. But Schlegel's Ateles 

 pan (Mus. Pays-Bas, VII, 1876, p. 180), from near Coban, 

 Guatemala, appears to have been based on specimens very 

 similar to those of the present series from Vera Cruz. He 

 compares his specimens with his "Ateles fuliginosus Kuhl" 

 (= A. vellerosus Gray), and refers especially to the absence 

 of the light color on the forearms and on the posterior ex- 

 tremities. The present series is therefore referred pro- 

 visionally to Schlegel's Ateles pan, to which a single specimen 

 collected by Dr. Buller at Chimalapa, Tehuantepec, formerly 

 identified with Ateles vellerosus (this Bulletin, III, 1890, p. 

 176), is also referable. 



II. CENTRAL COSTA RICA. 



The collection here under notice was made for the Museum 

 by Mr. M. A. Carriker, Jr., during the period from February 

 to July, 1902, mostly in or near the Irazu Range in central 

 Costa Rica. The collection numbers about 120 specimens, 

 referable to 23 species. The principal localities at which 

 collections were made are "Mount Irazu," Feb. 23 to April 

 21, part of the specimens (collected Feb. 23 to March 6) being 

 labeled simply "Mount Irazu" ; a part (collected March 13-22), 

 "Juan Vinas, Mount Irazu" (altitude 1113 meters); and 

 others (collected April 2-21), "Rancho de R. Jimenez" 

 (altitude about noo meters). Later, specimens were col- 

 lected at "Pozo Azul, Pirris Province" (May 14-26 and July 

 1-23), at San Jos (July 21), and at San Pedro, near San Jose 

 (July 29). Pozo Azul is on the Pacific slope, at an altitude of 

 about 200 meters.
