Marcus E 1951 (citation) pg. 108: 'Mecynostomum pellitum, n. sp. (Fig. 1-5), fro fine sand on the coast of the canal of São Sebastião, is 0.2-0.3 mm. long alive and has a uniformly high (6-8 micra) epicytium (k) with long cilia (6 micra). When the epicytium dissolves under pressure of the cover-glass, it shows its original epithelial structure. The back has 7 and each side 3 series of rhabdite-glands (h); each series contains about 30 glands. The cyanophil cephalic glands (g) open together with 2 rhammitogenous glands (r). The few annular fibres (n) lie partly on the outer, partly on the inner side of the longitudinal (m) ones. The latter form about 13 series around the body and unravel in front. Dorso-ventral muscles (p) carve the outline of the large ovocyte (o) that is 0.09mm. long. The neuropilema (c) of the brain is epicytial, its cells (d) are submuscular. The mouth (b) lies nearly in the middle; the endocytium (i) contains Protozoa and some Diatoms. The two lateral germ-zones are in common for male and female cells. Up to 8 coils of sperm (t), evidently come up from the same spermatogonium, occur on each side. The seminal vesicle (s) has glands (u) and bristles around its orifice. A penis is absent. The small antrum (a) opens (x) ventrally near the hind end. The vagina is often filled with loose tissue. The bursa (w) contains sperms and a mass of pink secretion as such was described in the seminal vesicle of M. minimum. The diploid number of chromosomes is 16. The eggs are freed through the mouth. The locomotion likens that of M. minimum. This species differs by its greater size, different height of the epicytium in various parts of the body, not serially disposed glands that contain two types of rhabdites, no rhammite-glands, entirely internal brain, and anteriorly confluent testes that are separate from the ovaries.'
