13.11 Periproct and Apical Disc Like peristome, periproct of echinoids is a similar
membranous system of plates covering the anus during lifetime. In regular
echinoids, periproct lies at the centre of aboral surface, diametrically opposite to ...
Periproct small, high above posterior margin. Fasciole distinct. Length, 25
millimeters; width, 21.9 millimeters; height, 15.6 millimeters. This form was
originally described by Morton in 1830; later, in 1833, it was considered by the
same writer as ...

A Field Guide to Fossils of Texas
Peristome is in center of test bottom, but periproct is also on under surface, unlike
regular urchins. Periproct large, pointed on inner end and rounded on outer if
such detail remains. Surface has only tiny perforate tubercles and appears fairly ...

Nucleolites with reduced extraxial skeleton are considered as "advanced":
genital 5, additional and catcnal plates are absent; the periproct opens between
two interambulacrum areas made of axial skeleton. 3 SYSTEMAT1C AND
TAXONOM ...

This fact demonstrates the strong morphogenetic connection between the apical
system and the periproct and helps to understand why the process of their
separation in many lineages of Irregularia went on in such a slow and
complicated ...

all other American species of the genus in the great size of its periproct. In this
feature it resembles H. macropyga (Agassiz), whose periproct is not pointed but
rounded at the back. Holectypus (Caenholectypus) castilloi Cotteau Plate 21, ...

In Echinosigra and Pourtalesia, the periproct rotates and becomes more and
more vertical during growth (Fig. 4 A-B-C). This rotation induces, almost
mechanically, the formation of the hood and rostum. In Spatagocystis, the hood
becomes ...

A New Theoretical Model for Growth of the Echinoid Test
The peristome and periproct are membranous areas containing, respectively, the
mouth and the anus. The periproct is located at the apex of the body in regular
echinoids, directly opposite the peristome, and the line passing through the
center ...

Sea urchin tests have a large central opening above for the anus (periproct) and
another below for the mouth (peristome). In Sand Dollars the peristome is at
center below, periproct at disk margin. Peristome and periproct are at front and
rear ...
