“Philomedes assimilis
(Plate I., figs 16-21. Plate II., figs. 1-6.)
Shell of the female seen from the side oblong, subcircular, height equal to two-thirds of the length, anterior extremity sharply angulated below at its junction with the wide truncated rostrum, posterior sloping steeply and forming a somewhat rounded, prominent angle at its ventral end; dorsal margin strongly arched, highest in the middle, ventral evenly but less strongly convex, terminating in front in a deep subrostral sinus and behind in an obtusely angular process. Seen from above the outline is oblong, ovate, twice as long as broad, greatest width situated in the middle, anterior extremity obtusely pointed, posterior produced and mucronate, lateral margins evenly arcuate. The shell of the male much longer in proportion to the height, rostrum and subrostral sinus much less pronounced, posterior extremity more narrowed and having a larger and more rounded ventral prominence; the squamous, marginal laminae of the rostrum are marked with numerous hair-like striae and are closely punctuated. The limbs and appendages do not present any special specific characters, but the hairs at the base of the claws of the post-abdomen of the male are more than usually conspicuous. Length of the female, 1.8 mm.
