Terfldvy Polyzoa of Victoria. 17 



Locality.— MuMy Creek. (T. S. Hall). 



There is in the specimen an oval hole through the cell wall, 

 with smooth sloping edges, near the thyrostome, which has 

 apparently been made by a small carnivorous univalve mollusc. 

 This is quite probable, as in my search for fossil polyzoa I found 

 many such molluscs, much smaller than a zooecium of a Cateni- 

 cella. There is also a small chlithridiate depression near the 

 upper angle on one side; the upper portion of the other side is 

 broken away. 



This is allied to C. specwsa, having two rows of pores ; but it 

 is much larger, and the avicularian processes are different. 



Calopopella dendrina, n. sp. (PL I., Fig. 8.) 



Zocecium (fertile only found) subtriangular ; lateral processes 

 broad, with avicularia at upper angles Front raised, smooth. 

 A'ittje very narrow. Thyrostome lofty, arched above, straight 

 below. Operculum' (which is in situ) of same shape. Ooecium 

 surmounting zocecium, ventricose, with broad, punctate I'idge 

 surrounding it ; front surface smooth, with linear depressed, 

 dendroid markings ramifying from a central one. 



Locality.— W\xMj Creek. (T. S. Hall). 



I have only seen the one figured ; it is particularly interesting, 

 as the operculum is iii situ, a circumstance which I believe has 

 not before been noted in the fossils. 



Caloporella cordata, n. sp. (PL I., Fig. 9.) 



Zocecia (fertile only found) obconic, with small spatulate, lateral 

 vittse having only a few pores in two rows. Thyrostome of upper 

 zocecium arched above and below, with a denticle on each side. 

 Ocecium cordate, adnate to zocecia with a falciform, depressed 

 area on each side ; the aperture is arched above, sinuous below, 

 with a small sharp sinus. 



Locality.— U.\xMy Creek. (T. S. Hall). A single specimen. 



Caloporella maculata, n. sp. (PL I., Fig. 10). 

 Lower zooecium subtriangular, smooth, with wide lateral 

 processes. Upper zocecium elongate, with wide lateral pi-ocesses ;
