Tertiary Polyzoa of Victoria. 7 



scattered irregularly over the surface, not confined in a scutiform 

 area. Dr. MacGillivray's figure of this species in his Monograph 

 (PI. I., Fig. 20) shows the inner finestrse more regularly disposed 

 than they are in the recent species, so much so that I think it 

 very probable it is not C. cribraria, but, a new species of 

 Digenopora very closely allied to D. compta. 



Catenicella haili, n. sp. (PI. I., Figs. 11 and 11^). 



Zocecia ovoid. Fenestras 9*1 1, pyriform, perforated. Thyros- 

 tome arched above, slightly curved below. Lateral processes 

 broad, convex, with infra-avicularian and pedal chambers. 

 Avicularia upon a broad protruding base. Supra-avicularian 

 processes extending upwards into a long, curved, spinous process. 



Locality.— IIowa}ooo\. (T. S. Hall). 



Allied to C. cincta but is very much larger and has peculiar 

 protruding bases for the avicularia. In the geminate pair the 

 pedal chamber on one side is broken away and in the upper part 

 the lateral processes are wider and more protruding than in the 

 single zocecia. 



Catenicella acuminata, n. sp. (PI. I., Fig. 12). 



Zocecia ovate. Fenestrse 11, pyriform, perforated. Thyros- 

 tome arched above, nearly straight below. Lateral processes 

 wide, with large infra-avicularian and pedal chambers, the 

 surfaces of which on one side are convex ; avicularia small, on a 

 level with the thyrostome ; super-avicularian processes with 

 hollow chambers, or perforations above the thyrostome ; outer 

 angle continued upwards into a very long spine. 



Locality. — Bairnsdale. (J. Dennant). A single specimen, 

 allied to C. halli but much larger, the superstructure above the 

 thyrostome is difierent and it wants the protruding base to the 

 avicularia. 



Catenicella papillata, n. sp. (PI. IL, Fig. U, 14^, 14/^). 



Zocecia elongate, front surface smooth. Fenestras 7. Lateral 

 processes broad, smooth, with very slightly depressed infra- 

 avicularian areas. Geminate zocecia with 9'11 fenestrse. 

 Thyrostome arched above, hollow below. Dorsal surface 

 covered with small, round, papillae.
