In the male, Fig. 10, on the same scale, the pleopods are long, slender, but simple cylinders pointing toward one another. These two figures also show the increasing longitudinal diameter of the anmulus in the female and its simple form in the male, as well as the reproductive openings upon the fifth legs in the male and the third legs in the female.

. The Biological bulletin. Biology; Zoology; Biology; Marine Biology. FIG. 10. but thirteen, and Fig. 5, fifty diameters. In the male, Fig. 10, on the same scale, the pleopods are long, slender, but simple cylinders pointing toward one another. These two figures also show the increasing longitudinal diameter of the anmulus in the female and its simple form in the male, as well as the reproductive openings upon the fifth legs in the male and the third legs in the female. In these females 11 mm. long the median groove of the annulus is much more evident than at first, but is still a simple groove as shown in Fig. 11 enlarged 200 diameters. The walls of the folded in and thickening shell that bound the deep and narrow groove are indicated by the broken line. In this preparation the epider- mis had shrunken far away from the shell and is indicated in optical section to show its invaginated state where it came under the cuticular groove. The groove seems to grow forward from the posterior face of the annulus and becomes more narrow and closed in anteriorly. At the anterior tip the groove was partly overhung by a cross fold, or tended to burrow under the surface as a short citl de sac. In different females, however, the groove had different lengths and more or less of this covering-over of the front end. In a specimen 10 mm. long the groove was longer and more narrow than the one above figured. In others of 11 mm. the anterior.
