With B. M. Pap. 273 (described and in part published by Kenyon in the Album Gratulatorium in honorem H. van Herwerden, Utrecht, 1902, pp. 137–142), which consists of a number of fragments from a papyrus book containing an unknown epic on the subject of Dionysus and his Indian expedition, is bound up a small fragment, evidently by a different hand. This (Pap. 273b) I have recently identified as from the Phaenomena of Aratus; and I therefore publish it here. Apparently no papyrus fragment of this poem has yet been discovered; there is, however, at Berlin (Pap. Ber. 5865) a portion of a commentary on Aratus, which has been published by Maass in his Commentariorum in Aratum Reliquiae, Berlin, 1898, pp. 556–558.
