The major purposes of our project are to obtain appropriate materials of onychophoran species for a phylogenetic analysis and particularly, to obtain basic neurophysiological data.The onychophoran animals are distributed in the Carribean and C.and S.American countries, so that this time-survey was made on Carribean countries such as Trinidada & Tobago, St. Lucia and Jamaica on October to November, 1998.In the report, first the natural history on onychophorans is described and then the result of our field survey in the Carribean area is given. There are many poluted areas by insecticide in the area. This means to threaten the animal. However, some good points to collect animals were found. One of them was the Blue Mountain area of Jamaica. We discovered a new locality of Onychophora in the area.Based on the materials obtained, nerrophysiological preliminary experiments were carried out. The result showed that, in the cetral and peripheral nervous systems of the Onychophora, there are immunoreactive neurons or neuronal processes to anti-serotonin-like antibody. The presence of the immunoreactive neurons is first reported in the Onychophora, with the presence of FMRFamide. And further, it is reported for the first time that serotonin has a role of neurotransmitter in the Onychophora.

我们项目的主要目的是获得有爪类物种的适当材料用于系统发育分析，特别是获得基本的神经生理学数据。有爪类动物分布在加勒比海和南美洲国家，因此本次调查1998年10月至11月对特立尼达和多巴哥、圣卢西亚和牙买加等加勒比国家进行了报告。报告中，首先介绍了关于描述了甲虫，然后给出了我们在加勒比地区实地调查的结果。该地区有多处被杀虫剂污染的地方。这意味着威胁动物。然而，我们发现了一些收集动物的好点。其中之一是牙买加的蓝山地区。我们在该地区发现了甲虫的新产地。根据所获得的材料，进行了神经生理学初步实验。结果表明，甲虫的中枢神经系统和周围神经系统中存在抗血清素样抗体免疫反应的神经元或神经元突起。免疫反应性神经元的存在首先在甲藻中被报道，其中存在 FMRFamide。此外，首次报道血清素在甲虫中具有神经递质的作用。
