The smaller avicularia have blunt mandibles. The colonies vary in general appearance. Some are profusely branched, with many secondary branches and rootlets, and present a dense mat-like appearance (Plate IX, fig. 3). Others, such as the colony from St. 1651, are more lax in growth.

The material from St. 1660 includes some specimens with long straight zooecia forming broad strap- like branches with as many as twelve series of zooecia. Other specimens from the same station have shorter, less straight, zooecia, and narrower branches. There is also varia- tion in the spines which are sometimes very stout, the median distal one being par- ticularly large. This is well seen, for example, in the material from St. TN 194.
