. Fig. 20. Pseudomma minutum A, anterior end of immature male in dorsal view, x 45; B, anterior end of adult female in dorsal view, x 36; C, endopod of fourth thoracic appendage, X45; D, genital organ of male, X45; E, fourth pleopod of immature male, x 45; F. telson and right uropod of immature male, x 45; G, telson and uropods of adult female, x 34. arming the inner margin of the endopods (Fig. 20 F, G). Telson triangular, very short, length equal to its breadth at the base and only slightly more than half as long as the sixth abdominal somite; lateral margins straight, converging evenly to the small apex; each armed with 2-3 very small spines, which are confined to the distal third of the length; apex narrowly rounded, armed with a pair of long spines nearly one-third of the telson in length, and a pair of median plumose setae (Fig. 20 F, G). Length of largest <J, 4'4 mm.; of $, 4-6 mm. Remarks. This species closely resembles P. roseum G. O. Sars in the form and proportions of the anterior end, the anterior end of the carapace, the eyeplates, and the antennal scale, but differs in having no serrulations on the antero-lateral margins of the eyeplates. It may at once be distinguished from all other species of the genus by its small size and by the very short triangular telson which in shape recalls those usually found in the genus Erythrops. Distribution. Pseudomma minutum was taken at four stations in the present collection, all situated near the Falkland Is. All the captures were made by day in water of 105-278 m. in depth.
