External characteristics of Polycelis remota: A, dorsal view of living animal; B. anterior end of living animal; C, anterior end of preserved animal; D, ventral view of posterior portion of preserved animal. Scale line equals 1 mm; G = gonopore, M = mouth pore, R = region of ventral gland. S = "; ynx. The posterior part of the animal tapers to a rounded point. Eyes are present and numerous, and extend across the margin of the head and along the lateral margins, ex- clusive of auricles, some distance posterior to auricles. The arc is interrupted at the midpoint of the anterior margin. The dorsal surface anterior to the pharyngeal re- gion with the low median keel extending anteriorly to the apex of the anterior margin. The pharynx is single, medially placed, and occupies about one third of the length of the animal. The inner muscle layers of pharynx are composed of an outer, thin longitudinal layer and an inner, thick circular layer. Rhabdites are present along the margins of the animal. Both mouth and genital pores open ventrally on the midline. The color of the dorsal surface of animal, exclusive of the area of digestive caeca, is olive, and the digestive caeca are brown to yellowish- brown. The pharyngeal region is a lighter whitish-yellow. Ventrally, the animal is grayish-white, and the region of the atrium and gland is lighter. The pharynx is unpig- mented.
