POLYZOA. 123 



specimens of this species. It is widely distributed around the coast, and apparently 

 very abundant. 



Localities : Gulf of Manaar ; off Galle ; off Mount Lavinia ; and Navakaddu Paar. 



Smittia trispinosa, var. spatulata (Smitt, 26). 

 Locality: Station XLVL, off Mount Lavinia. 



Smittia trispinosa, var. protecta, nov. 



This large variety has the peristome raised and in front, below the orifice, produced 

 into a long spout-like extension. Avicularia, not on every zocecium, are of enormous 

 size, reaching from above the orifice and bending and spreading so as to cover the 

 whole front wall of the zocecium, and having a blunt extremity. 



There are sometimes two small raised avicularia, one on either side of the orifice. 

 The finely punctured ocecium has a narrow, prominent arched rib across the front. 



Locality : Gulf of Manaar. 



Smittia tubula, Kirkpatrick (20). 



The present specimens of this form are of a pink colour. There are usually two 

 avicularia, one on either side of the tubular secondary orifice, pointing upwards. Two 

 of the oral spines, of which there are six, remain in front of the ocecium when present. 



Locality : Gulf of Manaar. 



Smittia rostriformis, Kirkpatrick (20). 



Avicularia on these specimens are sometimes pointing downwards, as figured by 

 Kirkpatrick, but sometimes upwards with the appearance of a spine on either side 

 of the orifice. In both cases the peculiar serrated edge of the beak is plainly visible. 

 Oral spines vary in number from two to six. In other respects the specimens agree 

 with the original description of the species. 



Locality : Station XLVL, off Mount Lavinia. 



Phylactella spiralis, n. sp. Plate, fig. 14. 



Zoarium forming small pink patches on shells. Zooecia arranged in radiating lines, 

 smooth or slightly roughened, areolated round the margin, with a much raised 

 tubular peristome and an avicularium raised to the margin of this on a semi-spiral 

 tube. Primary orifice, having a very wide denticle with sharp lateral points. 

 Secondary orifice, with from two to four spines above. Ocecium behind the tubular 

 peristome, smooth or slightly roughened like the zocecium. 



Localities : Gulf of Manaar ; off Mount Lavinia ; and off Galle. 



This species approaches most nearly to Pliylactella gcometrica, Kirkpatrick (21), 

 in form, but the one broad denticle instead of three and the difference in the position 

 of the avicularium, which resembles that of Lagenipora nitens (MacGillivray, 23), 

 makes it impossible to mistake the two species.
