POLYZOA. 113 



Microporella decorata, Reuss. 

 Locality : Gulf of Manaar. 



Berenicea prominens, Lx. [= Chorizopora brongniartii (Aud.)]. 



Localities : Gulf of Manaar ; off Galle, deep water ; and Station XL., off Watering 

 Point, 34 fathoms. 



Family: PORINID^. 



Porina magnirostris (MacGillivray, 23). 

 Locality : Gulf of Manaar. 



Gigantopora fenestrata, Ridley. 



On the most perfect of the few, small, incrusting colonies of this form there are 

 little branched spines, in between the perforations of the front wall of the zocecia. 

 The secondary, tubular orifice has a 4-toothed margin and avicularia are very long, 

 reaching from the base of the tube and extending beyond its margin. Where an 

 avicularium is absent the tube has a fissure in its place. Ooecia are present, low 

 down at the back of the tubular orifice, and perforated like the front wall of the 

 zocecia. 



Localities : Gulf of Manaar ; and off Galle. 



Lagenipora spinulosa, Hincks (8). 

 Locality : Gulf of Manaar. 



Lagenipora tuberculata, MacGillivray (23). 



There are several colonies corresponding to MacGillivray's description of this 

 species, but there are also among them some that have the hollow tubercles very 

 much lengthened, ending in points, or being jagged and irregular in outline. These 

 specimens have also simple or branched spines round the margin of the much raised 

 peristome. The front walls of the zocecia have punctures in between the spines ; the 

 peristome is granular. There are no avicularia, and no ocecia are present. 



Locality : Off Galle. 



Family : MONOPOEELLID^. 



Monoporella albicans, Hincks (6). 



An interesting point in the present example of this form is that the ocecia are in 

 most cases set a little " awry," a fact that Hincks thought merely a peculiarity of 

 the colony in his collection. There are none of the large avicularia present here. 



Locality : Gulf of Manaar. 



Monoporella lepida, Hincks (5). 

 Locality : Station LIIL, north of Cheval Paar, 7 to 10 fathoms.
