 STOMATOPORA GEMINATA (McG.). 



[Genus STOMATOPORA (Bronn). (Sub-kingdom MoUusca. Class Polyzoa. Order 

 Infundibulata. Sub-order Cyclostomata. Family Tubuliporidae.) 



Oen. Char. — Zoarium adnata, simple or irregularly branched ; branches linear or ligulate. 

 ZocEcia in single series or in more or less regular transverse rows.] 



Description. — Zoarium branched ; branches obscurely concentrically rug'ose ; 

 surface with numerous small, brown, white-bordered puncta or pores. Zocecia 

 separated by shallow sulci, opening in pairs or triplets; mouths projecting', turned 

 rectangularly forwards, and closely united together laterally throughout their length.

FLOSCULIPORA PYGM^A (McG.). 



[Genus FLOSCULIPORA (McG.). (Sub-kingdom Mollusca. Class Polyzoa. Order 

 Infundibulata. Sub-order Cyclostomata. Family Discoporellidje.) 



Gen. Char. — Zoarium small, pedunculate, the peduncle consisting of smooth tubes or ridges, 

 with interrening cancelli towards the upper part. Zooecia opening on the expanded summit, the 

 peristome produced, dimidiate or lacerated, with numerous intermediate cancelli.] 



Description. — Peduncle composed of polished tubes, close together below, 

 but separated above by intervening cancelli. Zocecia in distinct series at the margin, 

 but confused towards the centre ; peristome of the external produced, dimidiate, 

 bifid or lacerated, of the internal very little developed and frequently represented 

 by a small spinous process. Cancelli between the rows of zocecia, externally large, 

 towards the centre small and much resembling the zocecia.

Port Phillip Heads, Mr. J. Bracebridge Wilson. . 



This exquisite little species forms tufts about ^V of ^i mch high, 

 and resembles a microscopic bouquet of flowers. It is attached to 

 the zocecia of Catenicella. The external zooecia are very distinct, 

 those on the outside continuous with the outer tubes of the stem. 

 No doubt the whole peduncle is composed of the lower tubular 

 parts of the zooecia.
