rostrum, bearing two or three small spines on either side ; 

 large oval avicularia scattered over the zoarium ; remarkable 

 for the spines on the lower lip. 



Lepralia baccata. Spec. nov. 



Cells small, quincuncial, immersed, divided bj a raised line ; 

 surface coarsely granulated ; orifice oval, transverse, with a 

 smooth shining mammillary projection below ; ov-oecia reni- 

 form, transverse, coarsely granulated ; no avicularia ; color 

 purple ; encrusting stems of algse. 



Lepralia pocula. Spec. nov. 



Cells pyriform, sub-erect, smooth, obscurely corrugated 

 transversely, arranged in transverse, slightly oblique rows ; 

 opaque ; orifice large, orbicular flattened below, generally with 

 one or two small immersed avicularia (?) on the sides of each 

 cell ; encrusting stems of algse. 



Oellepora agglutinans. Button, Cat. Marine Moll, of 



New Zealand, p. 99. 

 Cbllepora edax. Busk, Trans. Micro. Soc, oi.s.^ I., p. 54. 



The South Australian specimens differ somewhat in habit 

 from the British tpye, but not sufficiently to make a specific 

 difference. 



Cellepora tubigera. Bush. (?) Crag. Polyzoa, p. 64. 



Several specimens of two varieties of cellepora are in the 

 collection, the cells of which resemble those of C. tubigera, but 

 are widely different in habit. Both encrust the stems of 

 algse. In one (var. 5) the zoarium is angled, the angles 

 running more or less longitudinally. In the other (var. ^ ) 

 the zoarium is also angled, but the angles form rather close 

 spirals round the encrusting stem. Many intermediate forms 

 occur, and it is evident that both belong to one species, but 

 whether it should be considered as G. tuUgera is doubtful. 



ESCHARA CONTORTA. Busk. (?) 



The type is from South Africa. 



EsCHARA (?) HUTTONI TATE.* SpCC. nOV. 



Zoarmm encrusting stems of algse, but branching out into 

 erect lobes ; color, rose to yeltow ; cells immersed, ovate, 

 coarsely punctured ; orifice rounded, with a sinuosity below, 

 and generally a small denticle on each side ; an ascending 

 cylindrical, tubular process supporting an avicularium, on 



* [This species was named E. tatei by the author, but as the name is pre- 

 occupied for a tertiary S. Australian form described by the Rev. J. E. 

 Tenison-Woods, Proc. Hoy. See, N.S.W., 1876, I have taken the liberty of 

 dedicating it to Mr. Hutton.— E. Tate.]
