The author was surprised at finding a higher number of chromosomes in this species than that encountered in the previous form. Counts in several adequate plates established that there are 29 distinct chromosomes having bivalent nature. As seen in Figures 12 to 15, the chromosomes vary'considerably in their size and shape. The configuration of some of the larger bivalents is strongly suggestive of subterminal or submedian fibre attachments. To the author's view, a few of the medium sized ones seem also to be of atelomitic nature. Four or five bivalents are extremely small in size. Outstanding in the haploid complement is a heteromorphic bivalent which is composed of a long rod-shaped element and a minute granular one, connected end to end with each other.
