. Fig. 13. Boreomysis insolita A, adult female in dorsal view, x 10; B, anterior end of adult female in lateral view, x 10; C, profile of anterior end of carapace and eye, x 10; D, right antennular peduncle of adult female, x 30; E, right antenna of adult female, x 30; F, endopod of second thoracic appendage, x 30; G, second pleopod of male, x 30; H, third pleopod of male, x 30; J, telson and left uropod in dorsal view (adult female), x 30. Remarks. This species can readily be recognized by its small size and delicate slender form and by the rounded uptilted anterior margin of the carapace showing no trace of a rostral angle. The form of the antennal peduncle is quite distinctive and I know of no other species in the genus which has a similar form. The unusually long spine at the distal end of the outer margin of the scale and the long terminal spine arming the apical lobes of the telson together with the few spines arming the lateral margins of the telson make the species readily recognizable. Few and relatively long spines on the margins of the telson are frequently a sign of immaturity, but in the present material there are several definitely adult specimens of both sexes. Distribution. The specimens were taken in depths of 250-100 m., 100-50 m. and 50-0 m. at two stations in the Benguela Current to the west and the south-west of Walvis Bay, South Africa.
