Bud induced at ninth segment. Age, 28 days. C, extra part. of these buds (Fig. 15), implant 14-15, consisted ventrally of probably 7 segments. The anal segment and collar were complete. No setae were evident. A long mid-ventral anal cirrus was present, but the others were short. The last of these buds (Fig. 16), implant 13-14, consisted dorsally of at least 3 setigerous segments followed by an asetigerous region. Ventrally there was no evidence of segmentation. The anal segment was complete but with an anal collar which was very short on the dorsal side and without distinct cirri in that region. This anal seg- ment, however, did not occupy the entire end of the bud but was as- sociated mainly with the ventral half of this region. The dorsal half.
