Polyzoa Entoprocta and Ctenostomata. 
vertically above the orifice when the polypide is retracted. Fig. ^a, pi. i, shows the 
structure of the orifice so far as it can be made out in the material at ray disposal. 
Polypide. The polypide has the structure normal in the genus, but is remark- 
able for the great length of the slender-walled oesophagus and for the broadly pear- 
shaped outline of the stomach, which occupies a relatively larger part of the space 
available in the zooecium. The tentacles are long and slender and probably number 
i6. The intestine is bulky. Funiculi cannot be seen in my specimen and I have 
not been able to detect the collar precisely. 
Musculature. All the muscle-fibres are remarkably stout, especially those of the 
retractor muscles. The parietal muscles are short and entirely lateral in position. 
They are variable in number and arrangement. The " pyramidal " muscles connected 
with the orifice are attached to the retractile part of the ectocyst very low down and 
are arranged in three groups, two anterior (distal) and one posterior (proximal). 
Gonads. One of my mounted zooecia contains a ripe testis. It consists of rather 
discrete groups of cells situated on the floor of the zooecium proximad of the stomach 
and some distance from the proximal end of the zooecium (pi. i, fig. 5). 
Buds. The position of the primary lateral buds seems to be variable; sometimes 
they are situated much nearer the proximal end of the zooecium than is usual in 
P. ehrenbergi or P. elongata. 
In one zooecium a young resting-bud occurs in the distal part of the zooecium. 
It consists of a broadly oval mass of rounded cells densely packed with food-granules. 
The upper surface is smoothly rounded, but below the outline seems to be irregular. 
A thin chitinous investment has already been deposited round it. The length is 
01477 mm. and the greatest transverse diameter 0'i02 mm. The polypide in this 
zooecium is not markedly degenerate. 
Type. No. 7194/7 Z. E. V. in the register of the Indian Museum (Zool. Survey 
of India) : mounted in Canada balsam on a slide. 
Locality. Lampam, at the edge of Patalung R near its entry into the Tale Sap, 
Singgora Province, Peninsular Siam : January, 1916: in permanently fresh water. 
The most striking feature of this new species is its pentagonal orifice, in which 
it resembles Potsiella erecta, I^eidy. From that species, however, it differs entirely in 
the form of the zooecium, and, so far as can be seen at present, there is no reason for 
separating it from the genus Paludicella. 
Family VICTORELLIDAE. 
Genus Victorella, Kent.

Most species of the genus are found habitually in brackish water on or near the 
coast, but the genus has been recorded from Lake Tanganyika in Central Africa, the 
Birket-el-Qurun in Egypt and Issyk-kul in Central Asia. Loppens found the common 
European form {V. pavida, Kent) in marine oyster-beds on the coast of Belgium and
