leads to the intestine (i) which forms a short loop. The rectum is straight and ends with a two-lipped 

 anus lying level with the transverse bar separating the third and fourth rows of stigmata. 



Vascular process. A slender vascular process (v.pr.) arises from the left side of the abdomen and 

 passes down below the zooid into the common test of the colony. Some of these processes, but not 

 all, extend down into the stalk of the colony. 



Gonads. In the compound colony all the zooids were male, but two of the single colonies had both 

 male and female zooids ; the third single colony was in degeneration.

Text-fig. 20. Sycozoa anomala sp.n. (St. 929): A, female zooid; B, abdomen of male zooid; C, brood pouch with embryos. 



The ovary (ov .) lies slightly behind the intestinal loop, but in contact with it, and bulges out from 

 the abdomen to form a small sac-like projection recalling the condition in Distaplia. The ovaries 

 examined contained a group of ova of various sizes. 



In male zooids the testis (t) is a rosette of six to ten wedge-shaped follicles contained in a projection 

 from the abdomen similar to that accommodating the ovary in female zooids, but generally larger. The 

 sperm duct (s.d.), arising from the centre of the rosette, loops back before passing forward beside the 

 rectum (Text-fig. 20 B). 



Many of the female zooids had well-developed brood pouches (Text-fig. 20 C). These are rather 

 short, strongly coiled, and usually contained from nine to eleven embryos.
