Bryozoa from Madeira . By A. W. Waters. 11 
collected by the ‘ Challenger 5 Expedition between Fayal and Pico, 
must remain, as canalifera , as it differs in having the ovicell thrown 
back and not imbedded in the next zooecium ; it has not the largo 
punctures, the peristome is different, and, what is of most import- 
ance, the opercula of the two forms show characteristic differences. 
Mr. Busk makes L. canalifera B. a synonym of his L. Mangne - 
villa Aud. ; but from the above comparison we must take it that there 
are two species from localities not far apart. 
Lepralia inner onellif or mis sp. nov., plate III. fig. 21. 
Zooecia ovate, distinct, large ; the end of the pore-tubes which pass 
to the base form a circular line on the front ; surface granular and on 
the outer part punctured : a small mucro turned over the aperture, but 
not directed inwards. Oral aperture with the distal end rounded, 
the sides and proximal edge nearly straight, with lateral denticles. 
Operculum with the muscular ridges at the side. There are six oral 
spines. On one or both sides, lower down than the aperture, a raised 
triangular avicularium, with a complete bar. The avicularia are 
pointed downwards, and are often of very unequal size. Ovicells 
unknown. 
The name is given in consequence of the similarity in appearance 
to Mucronella coccinea. 
Lepralia contracta sp. nov., plate III. figs. 4-6. 
Zooecia incrusting, distinct, ovate or rectangular ; surface granular ; 
pores round the border not always distinct. Small semicircular or 
large spatulate avicularia at the side of the oral aperture. Oral aper- 
ture contracted at the side and rounded below ; six oral spines. Ovicell 
with the front perpendicular, flat, with an area like that of Schizoporella 
biaperta. One specimen has neither avicularia nor ovicells. 
Schizoporella vulgaris (Moll), plate III. figs. 9, 10, 11. 
This was described from Madeira by Busk as Lepralia alba , and 
the specimens examined by me do not show the umbo which occurs 
frequently on the Naples specimens. The zooecia and oral apertures 
are both somewhat larger than in the Naples specimens. To each 
zooecium there are about twenty pore-chambers. 
Loc. British ; Naples, Rapallo, Yillefranche s. M., Adriatic (H.),

the Tertiaries from various localities.
