All x 26. borne close to the apex and form, with the graduated apical spines, a regularly graduated series. Apex armed with three pairs of long spines, which increase in length towards the middle line; median pair of spines about one-fifth of the length of the telson; pair of median setae present (Fig. 16G). Length. Adult breeding females from station 219 measured 5-5 mm. from the anterior margin of the eyeplate to the apex of the telson and two adult females from station 229 measured just over 7 mm. The largest specimens were two males which measured 8-5 mm., from station 801. Remarks. This species has been taken with P. sarsi, but may be readily distinguished from it by its smaller size, by its comparatively shorter and thicker antennules and antennae, by the longer apex of the antennal scale and, above all, by the entire margins of the eyeplates. I have been much worried over the specimens which I have referred to this species, because they display individual differences in
