136 Australian' Polyzoa, 



L. marsupium. 



Cells small, distinct, arranged in longitudinal lines ; 

 upper part, immediately below the lower lip, forming a large 

 rounded pouchlike projection ; mouth with several small 

 spines on the upper margin. Ovicell small, globular. 



On shell. 



Family CELLEP0RIDM 



Genus CELLEPORA, Falricius. 

 C. costata. 



Cells very irregular, prominent ; mouth surrounded by a 

 variable number of thick processes, each bearing an avicu- 

 larium on its internal surface ; processes and cells ribbed. 

 Ovicell small, globular. 



Wilson's Promontory and Queenscliff, on zoophytes. 



This very distinct and beautiful species occurs in small 

 masses adhering to polyzoa and zoophytes. The cells are 

 prominent ; the mouth is arched above, with a deep wide 

 notch in the lower lip, and is surrounded by a variable 

 number of thick processes. In some very prominent cells 

 these are scarcely apparent, the whole thick rim being occu- 

 pied by the rounded ends of the ribs ; in others there are 

 one, two, three or even more prominent thick processes, on 

 the inner surface of each of which is a small avicularium. 

 These processes and the more prominent cells are beautifully 

 fluted longitudinally. The ovicell is small, globular, and 

 smooth, or with a sculptured area in front. 



C. platalea. 



Cells small, very irregular ; mouth very irregular, some- 

 times with a large rostrum at one side, sometimes with a 

 small one also. Numerous avicularia scattered irregularly 

 over the polyzoary, mandible very long, spoon-shaped. 

 Ovicell rounded, partly immersed, marked with radiating 

 lines. 



Queenscliff, on algae. 



A small species allied to C. exigua. The cells are very 

 irregular ; and the mouth varies greatly ; sometimes no ros- 

 trum can be made out, at other times there are one or two. 

 It may be recognised by the numerous scattered avicularia 

 with the very long mandible resembling that of Eschara 

 platalea or the bill of the spoonbill, and by the small ovicell 

 marked with radiating lines.
