304 A. W. AVATEKS ON CHILOSTOMATOrS BEYOZOA FROM
which the zooecia are formed, and in this respect and the shape and
size of the zooecia it much resembles C. fossa, Haswell ; but no
avicularia are found on the colony. I have a small globular colony
(4 millims. diam,) from the Crag of Leiston, with the oral apertures
of about the same size, and a similar plate directed inwards. This
Pig. 1. — Zooecia of Cellepora divisa, sp. n., showing apertures.
(Enlarged 2b diam.)
Crag fossil has a rostrum below the aperture with a terminal avicu-
larium, and has plain globular ovicells. Possibly this is the armed
condition of the present species.
Loc. Mt. Gambler.

Cellepora mamillata, var. atlantica, Busk, Chall. Rep. Polyzoa,
p. 199, pi. sxxv. figs. 4, 5, 13.
In a specimen from the River-Murray Cliffs the zoarium incrust-
ing a sheU is raised into large prominent mamilLations. Oral
aperture nearly round, flattened below, about 0-18 millim. diameter.
Avicularia projecting above the zocecia, with large triangular man-
dibular openings on the median line on the internal aspect.
The mamillation of the zoarium occurs in a very large number
of Celleporoe and cannot be looked upon as a character of specific
value. C. mamillata only differs from C. pumicosa, Busk, in the
shape of the aperture.

A specimen from the River-Murray Cliffs is dome-shaped, re-
sembling Lunulites. The zooecia are round, much raised, and
smooth ; below the oral aperture there are small oral avicularia with
rounded openings, but I do not find any vicarious avicularia (ony-

chocellaria) ; above the aperture there are two spines ; aperture

Public domain

This work is in the public domain in its country of origin and other countries and areas where the copyright term is the author's life plus 70 years or fewer.


This work is in the public domain in the United States because it was published (or registered with the U.S. Copyright Office) before January 1, 1929.

This file has been identified as being free of known restrictions under copyright law, including all related and neighboring rights.

This tag is designed for use where there may be a need to assert that any enhancements (eg brightness, contrast, colour-matching, sharpening) are in themselves insufficiently creative to generate a new copyright. It can be used where it is unknown whether any enhancements have been made, as well as when the enhancements are clear but insufficient. For known raw unenhanced scans you can use an appropriate {{PD-old}} tag instead. For usage, see Commons:When to use the PD-scan tag.


Note: This tag applies to scans and photocopies only. For photographs of public domain originals taken from afar, {{PD-Art}} may be applicable. See Commons:When to use the PD-Art tag.
