) and with a variable outline depending on the substrate to which the shell is fixed. It can have a drop-like aspect (Pl. 5, Fig. 2a; Pl. 6, Fig. 1a) but often it has an apple-shaped outline (Pl. 5, Fig. 1a; Pl. 6, Fig. 2). The maximum width (W) is at the mid-dorsal valve. The value of the length to width (L/W) ratio is constant and the shell keeps its outline unchanged during growth (Text-Fig. 7). The whitish shell is slightly longer than wide and is mainly cemented to the substrate by the posterior part of the ventral valve. Due to this

of attachment, the ventral part of the shell is often distorted (Pl. 5, Fig. 1d; Pl. 6, Fig. 1b, 1d). Rarely, the fixation of the shell occurs on its lateral part (Pl. 6, Fig. 2), a situation illustrating the strong influence of the substrate on the external shape of the shell.

The shell is strongly ventribiconvex (Pl. 5, Fig. 1b; Pl. 6, Fig. 1b), the dorsal valve being relatively flat, lid-like, except for its median part, which is slightly convex. During growth, the thickness of the shell increases relatively to its width, but the value of the thickness to width ratio (T/W) is not significantly modified (Text-Fig. 7). In dorsal view, the shell is sometimes cordiform as its anterior commissure is emarginate. In this case, a shallow median sulcus can develop at the anterior margin of the ventral valve (Pl. 5, Fig. 1a, 1c; Pl. 6, Fig. 1a, 1c) but this character is frequently absent. In lateral view, the entire shell is lifted from the substrate anteriorly (Pl. 5, Fig. 1b; Pl. 6, Fig. 1b), its anterior part tending to be in a more elevated position than the posterior one. Such a geniculation of the ventral valve is common in thecideide brachiopods as illustrated by

The interarea and the convex rugideltidium are usually straight but often they may be strongly curved to the right or to the left. The anterior part of the rugideltidium is normally smooth but, if this surface is eroded, the internal structure of the rugideltidium becomes visible and is made of numerous irregular cavities that are not endopunctae (Pl. 5, Fig. 2b; Pl. 6, Fig. 5c).</paragraph>

Most of the morphological characters show a linear variation when compared to value of the width of the shell (Text-Fig. 7). However, the best fitting relation between the length of the interarea and the width of the shell is an exponential variation (Text-Fig. 7). This explains the big difference between the beak length in juveniles and in adult specimens (

The ventral valve has a drop-like, slightly bilobed and cordiform outline due to its emarginate anterior commissure (Pl. 5, Figs. 1l, 2c; Pl. 6, Fig. 5a). All around the commissure is a smooth peripheral flange, which seals the shell when the valves are closed. The commissure is limited internally by a peripheral rim with a smooth external side and a row of more or less regular, strong tubercles on the internal side (Pl. 5, Fig. 2c, 2e; Pl. 6, Figs. 5a).

At high magnification the surface appears to be ornamented with small spinous asperities (Pl. 7, Fig. 1a). At higher magnification, two kinds of spines are discovered: there are small narrow cylindrical spines (less numerous) and there are wider conical structures that are more numerous (Pl. 7, Fig. 1a–b).

In male specimens, the lophophore is developed regularly whereas in females, the lophophore is interrupted posteriorly, allowing the development of a pair of specialized median tentacles (Text-Fig. 6.2a, c). A complete ontogeny of the lophophore is not available as trocholophe and other intermediate stages of growth were not found in our limited material preserved in ethanol.

The ridges limit the future development of the median depression. The median ramus, which appears as a pointed knob placed at the posterior part of the submedian ridges (Pl. 7, Fig. 5b–c), is related with the jugum, which is connected with the growing major intrabrachial lobes. These new structures are raised from the dorsal valve floor.</paragraph>
