POLYZOA. 115 



Schizoporella sanguinea (Norman). 



Avicularia are usually present on these specimens. They are long and pointed 

 and raised, a pair on each zocecium, situated at their extreme upper angles, above the 

 orifice and directed downwards and inwards. 



Locality : Off Galle. 



Schizoporella magnifica, Hincks (11). 



The peculiar distinctive ocecia of this species are not present on the one colony in 

 this collection, which is deep red in colour. The long pointed sinus, the pairs of 

 upward pointing avicularia, and the reticulate front wall of the zocecium, without a 

 raised margin, accord with Hincks's description of the species. 



Locality : Off Galle. 



Schizoporella depressa, Phillips (25). 



There are some colonies of a pink colour corresjionding with the figure and 

 description of this species. The orifice of the zocecium is deeply sunk, the front wall 

 rising into almost an umbo below it, and calcareous ridges radiate from this to the 

 margin, leaving large, loop-shaped areolations between them. The small rounded 

 avicularia, on one or both sides of the orifice, are sunk below the surface, together 

 with the orifice. Ocecia are smooth and hyaline or ridged, and have an oval area on 

 either side of them. 



Localities : Gulf of Manaar ; and off Mount Lavinia. 



Schizoporella triangula, Hincks (5). 



The specimens of this form in the present collection have the triangular orifice, the 

 raised margins and punctured surface of the zocecium, with small avicularium pointing 

 downwards from just below the orifice, although this last is smaller and never raised 

 on an elevation. There is a second avicularium lying transversely on a separate area 

 above the orifice. Busk (1) mentions, but does not figure, a second avicularium with 

 a slender, spear-shaped mandible which corresponds with these, with the exception 

 that his are described as lying vertically and these are transversely placed. Where 

 ocecia are present, they take the place of these. They are large, covering nearly the 

 whole of the zocecium above the one to which they belong, as described by Busk, but 

 are sub-immersed and have no nodules, being punctured like the zocecium. 



Localities : Gulf of Manaar ; and East Cheval Paar. 



Schizoporella subsinuata (Hincks, 9). 



There are a few colonies of a grey-white colour, incrusting pieces of broken shell, 

 having the zooecial characters of this form with the addition of numerous avicularia, 

 which in Hincks's specimens did not exist and which were rare in MacGillivray's (23). 

 They have long, pointed mandibles, and are usually pointing downwards, like those in
