The corresponding organ of the female is smaller than that of the male, but still is large ; it is a hollow cone lined by peritoneum and containing the ends of the ovaries, which have a common orifice of large size at its free end, which is spongy. Two males and a female with ripe ova, from the Andaman Sea, 405 fath. (1897). The largest male is nearly 7 inches long, the female not quite 6 inches. This species is at once distinguished from D. brachysoma, Gthr., and D. Rivers-Andersoni, mihi, by the broad frog-like head and snout; in those species the occiput is high and the snout is much depressed, with an upturned tip, but in this. Male orgau of Diplacanthopoma raniceps, x 4. species the head is broadly conical and gently and evenly declivous from occiput to tip of snout. Another difference is that in this species the two spines of the operculum are hidden beneath the skin, whereas in both the other species they are very sharply prominent. From J).
