although individuals of this type do occur. The zooecia are small, rang- 

 ing in length from 0.35 to 0.45 mm, and in width from 0.11 to 0.13 

 mm proximally, and 0.09 to 0.11 mm distally. All of the zooecia have 

 a broad rounded proximal portion, where 1 or 2 small, pointed, spine- 

 like protuberances may appear. The zooecia gradually taper distally, 

 where, shortly beyond the point midway between the two extremities, 

 they become wrinkled transversely. Some of the zooecia exhibit a 

 setigerous collar protruding from the aperture. The polypide is pro- 

 vided with a large and prominent gizzard. The tentacle number is 8, 

 as determined from examination of serial sections. 



Although erect, Buskia seriata has comparatively short zooecia, differ- 

 ing from B. socialis which, according to Marcus, has zooecia measuring 

 0.75 mm in length. Being erect, it is easily distinguished from the 

 reptant B. nitens with its minute creeping zooecia.
