lower lip which is bent downward. The condition, however, is equally common in S. campanularia. The gonangia are large and pear-shaped, but apt to be very irregular in outline; the largest which I saw were simply rounded at top; shorter ones were more or less truncate, which is presumably a matter of development. They taper down to a very narrow base, smaller than that of the hydrotheca-stalks, and those which I saw were mostly erect, while those of S. campanularia are more often decumbent. Specimens from Professor Chilton were very perfectly preserved, the perisarc not having suffered the slightest contraction; one of Coughtrey's specimens, from the Dunedin Museum, had been dried, and, as always happens in such circumstances, the thick perisarc of the hydrothecae was much shrivelled and distorted. The hydrothecae were somewhat shorter than in Professor Chilton's specimens, but this may be more or less Fig. 4.—Silicularia bilabiata (Coughtrey). × 40. the effect of the general shrinkage. The gonangia were on Coughtrey's specimen, and probably some of the irregularity which characterizes them is due to their having been dried, though they appear to have suffered less than the hydrothecae and their pedicels. The latter seem to have been originally thin-walled, a condition accentuated no doubt by shrinkage due to drying. Hilgendorf has classed Eucopella campanularia as a synomym of C. bilabiata, but this is erroneous, and there is scarcely a doubt that his Hypanthea asymmetrica is really the same as E. campanularia.
