摘　　要：报道厦门港球型侧腕水母的染色体制备方法及核型分析结果 .球形侧腕水母染色体数目 2 n=30 ,可配成 15对同源染色体 :8对为中部着丝点 ( m) ,4对为亚中部着丝点 ( sm) ,1对为亚端部着丝点 ( st) ,2对为端部着丝点 ( t) ,其核型公式为 2 n=30 =16m+8sm +2 st+4t,NF=54,第Chromosome preparation and karyological analysis of Pleurobrachia globasa , a kind of Ctenophore, inhabiting in Xiamen Waters were studied and reported. The chromosome number of this animal was determined to be 2 n =30, which can be partnered to 15 pairs of homolgous chromosomes. The karyotypic formula of 2 n =30=16 m+8 sm+2 st+4 t, NF=54 was suggested. Chromosome number 2 was considered to be SAT chromosome. Methodology on the chromosome preparation of this gel animal was discussed.
