180 Descriptions of JSfevj, 



Schizoporella pachnoides, n. sp. Plate I., fig. 8. 



Zoarium encrusting. Zooecia elongated, irregular in shape, 

 separated by distinct grooves, with an elevated line at the 

 bottom; surface minutely covered with small elevations, or, 

 from the opening of these, white bordered pores; mouth 

 lofty, horse-shoe shaped, with a wide, deep sinus in the lower 

 lip ; margin thickened, especially below; upper border becom- 

 ing thickened and raised with age. An avicularium with 

 the triangular mandible pointing straight or obliquely down- 

 wards, on a slight elevation below the mouth. 



Port Phillip Heads. 



Schizoporella dcedala, n. sp. 



(= S. insignis, M'G.) 



In the Trans. Roy. Soc, Vict., 1882, I described a species 

 as S. insignis, not being aware that the specific name had 

 been a short time previously applied by Mr. Hincks to an 

 African species. Mr. Hincks subsequently described the 

 present species from Port Phillip Heads, referring it to 

 Mr. Waters' fossil S. conservata, an indentification which is 

 at ]east doubtful. As the specific name was previously used 

 for another species, I propose naming the present S. dosdala, 

 = S. insignis, WG.=S. conservata, Hincks (not Waters). 



Family Cellepoeid^. 

 Lagenipora nitens, n. sp. Plate I., fig. 1. 



Zooecia oblique at the edges of the zoarium, erect towards 

 the centre, smooth; primary mouth circular or sub-circular, 

 with a small oval avicularium at one side ; secondary mouth 

 formed by a tubular peristome, separated by a narrow con- 

 stricting collar; orifice with a spinous process on each side, 

 between which is the original oral avicularium, carried 

 upwards on a semi-spiral tube, widened above, and ending 

 in a clavate projection. Vicarious avicularia broadly spatu- 

 late. 



Port Phillip Heads, Mr. J. B. Wilson. 



Of this interesting species I have only a very minute 

 specimen on a piece of shell. It is related to Mr. Hincks's 

 Phylactella lucida, afterwards referred by him to Lageni- 

 pora, and to his L. spinosa. The manner in which the 

 small avicularium of the primary mouth is carried up on a 

 semi-spiral tube with the growth of the peristome is very
