Occurrence. St. 1686: Victoria, Australia, o m. 



Colony. The colony consists of a bunch of zooids united only at their lower ends where a narrow 

 stalk joins a stouter cylindrical stem. This is attached to the substratum by an expanded base. 



3.0 mm 



Text-fig. 15. Podoclavella cylindrica (Quoy & Gaimard) (St. 1686): Zooid. 



Zoom (Text-fig. 15). Large zooids reach a length of 1 1 mm. but many of the zooids in the colony 

 are much shorter. The body is widest anterior to the middle and tapers towards the base, where it 

 abruptly narrows to join the stalk. 



Thorax. The oral siphon (o.s.) does not occupy the extreme anterior end of the thorax, being instead 

 displaced slightly down the ventral border. This siphon is also curious in being sharply bent in a 

 ventral direction. The atrial siphon (a.s.) is terminal. Both siphons have numerous circular muscles. 

 Fifteen to twenty slender muscles pass obliquely across the thorax and abdomen.
