An incomplete mandibular fragment of a cebine monkey from an early Holocene Haitian cave deposit adds to the small but growing list of fossil Antillean primates. The jaw is of the correct size to belong to the same taxon as the partial maxilla of "Saimiri" bernensis from the Dominican Republic. Both finds probably represent a single species whose proximate ancestry lay closer to Cebus than to Saimiri, although more evidence will be required to substantiate this. No close relationship of the Hispaniolan fossils to the Jamaican platyrrhine Xenothrix is indicated. How monkeys managed to penetrate the West Indies is a biogeographical puzzle of the first order. Geographical vicariance events, island-hopping, and purposeful or inadvertent introduction by humans seem rather implausible devices. On the whole, long-distance, over-water rafting from the Americas remains the most likely mechanism for past land vertebrate immigration into the Caribbean.
来自全新世早期海地洞穴沉积物的一只僧面猴下颌骨碎片，为数量虽少但不断增加的安的列斯灵长类化石名录增添了新成员。这块下颌骨的尺寸与来自多米尼加共和国的“松鼠猴”伯氏种部分上颌骨所属的分类单元相符。这两处发现可能代表同一个物种，其最近的祖先与僧帽猴的亲缘关系比与松鼠猴更近，不过还需要更多证据来证实这一点。并未表明伊斯帕尼奥拉岛化石与牙买加阔鼻猴Xenothrix有密切关系。猴子是如何成功进入西印度群岛的，这是一个首要的生物地理学谜题。地理隔离事件、跳岛以及人类有意或无意的引入，似乎都不太可能。总体而言，从美洲进行远距离水上漂流仍是过去陆地脊椎动物迁入加勒比地区最有可能的机制。
