Ophiuroiden, p. 29. Although this species is not represented in the material collected by the Discovery Committee, I may say some few words about it. The type oi A. Etigenioe was never figured. Thinking it desirable to have that done, I applied to my friend Professor Sixten Bock of the Stockholm Museum, asking him to lend me the type specimen for this purpose, which he very kindly did. It is in rather poor condition, with all the arms broken oflF close to the disk; but the disk is sufficiently well preserved to afford a drawing of the oral side, which is given in Fig. 21. The dorsal side of the disk very closely resembles that shown so ex- cellently in pi. 4, fig. 9, of Clark's Catalogue of the Recent Ophiurans; there is thus no reason to give a special drawing of it. In the figure of the oral side of a specimen from the Swedish Antarctic Expedition given by Koehler (op. cit., 1923, pi. xiv, fig. 7) the shape of the buccal shields is somewhat different from that of the type specimen (Fig. 21), the outer lobe being more distinct. As these specimens from the Swedish Antarctic Expedition (which Pro- fessor Sixten Bock has likewise sent me for examination) otherwise closely agree with the type, and as moreover they show some variation in the shape of the buccal shields— some even being exactly as in the type—no weight, of course, can be laid on this slight difference. The examination of some of the specimens from the Swedish South Polar Expedition shows this species to be viviparous. I have found only female gonads, even in young specimens of only 5 mm. diameter of disk; the gonads here
