Abstract: The karyotype of black-lipped pika (Ochotona curzoniae) was examined and described as follows:The diploid chromosome number was 2n=46. Among autosomes there were 1 meta-centrics, 9 submetacentrics and 12 telocentrics. The X chromosome was a metacentrics and the Y chromosome was telocentrics.It is different in chromosome number from Ochotona daurica.

Key words: Black-lipped pika, Ochotona curzoniae, Karyotype, Chromosome

摘要: 本文报道黑唇鼠兔的染色体组型。证明黑唇鼠兔染色体数目2n=46,有别于达乌尔鼠兔,是一个独立的种。
