Loc. 8. Africa, 150 fath. (Chall.) ; Noumea, New Caledonia (Ph.) ;

Hartmeyer. 
ScHIZOPORELLA MUCRONATA (Smitt). 
Hippothea mucronata, Smitt, ‘Floridan Bryozoa,’ p. 45, pl. 8. fig. 169. 
Schizoporella mucronata, Waters, Ann. Mag. Nat. Hist. ser. 6, vol. iv. p. 10, pl. 2. fig. 9. 
The specimen from the Red Sea entirely corresponds with the one I 
figured from New South Wales. 
Loc. Florida (Sm.) ; Green Point, N.S. Wales ; Um el Jerman, Gulf of 
Suez, collected by Hartmeyer. 
ScHIZOPORELLA PES ANSERIS (Smitt). 
Hippothoa pes anseris, Smitt, “ Floridan Bryozoa,” p. 48, pl. 7. figs. 159, 160. 
Mastigophora Dutertret, var. pes anseris, Kirkpatrick, Ann. Mag. Nat. Hist. ser. 6, vol. 1. 
p- 77; Thornely, ‘ Manaar,”’ p. 117. 
Schizoporella pes anseris, Waters, “ Bry. from Madeira,’ Journ. R. Micr. Soc. (1899), p. 11, 
pl. 3. figs. 7, 8. 
Mastigophora was separated from Schizoporella as having vibracula; but 
this species has avicularia, and therefore I retain it with Schizoporella, and it 
belongs to the S. Cecil, Aud., group. 
Loc. W. off Tortugas (Sm.); Madeira (Wat.) ; Mauritius (Kzrkp.) ; 
10 miles off Galle, 34 fath. (Thornely); Gimsah Bay, Gulf of Suez, and 
lat. 16° N., long. 41° W., collected by Hartmeyer. 
ScHIZOPORELLA Burnarpit (Savigny § Audown). (Plate 1%. figs. 7-9.) 
Cellepora Bernardi, Savigny, Expéd. de ’Egypte, Zool. pl. 7. fig. 7; Audouin, Expli- 
cation Sommaires Zool. p. 288, p. 64. 
Schizoporella depressa, Philipps, “ Polyzoa from the Loyalty Isles, &c.,’’ Willey’s Zool. 
Results, pt. iv. p. 445, pl. 42. figs. 6, 6 a (1899) ; (?) Thornely, “ Manaar,” p. 115. 
The zocecia are irregularly placed, more or less erect, and are ovate with 
broad radiating ribs. The oral aperture has a broad sinus. The operculum 
has the muscular attachments distant from the border. There is a small 
semicircular avicularium at each side of the aperture, and in the older zocecia 
a raised ridge encloses a pit in which are the aperture and the avicularia. 
Occasionally there are one or two of the small avicularia on the distal border ; 
there are a few vicarious avicularia, with duck-bill mandibles, scattered about. 
The ovicell is not very prominent, rather thrown back, fairly large, with 
large perforations. The ovicells were not known to Miss Philipps, and 
Miss Thornely described them as “smooth, hyaline, or ridged, and have an 
oval area on either side of them.” It therefore seems that she must have had 
another species before her.
