Fam. 2. Gumminida .

The specimen of Chondrilla nucula , to which I have alluded, is subglobular, lobate, about in. high and 2 in. in hori ­ zontal diameter now in its spirit-preserved state; if dried this would be considerably less. When fresh the colour was much the same as it is now, viz. “ dark grey, nearly black.” In short, it is precisely the same as the Adriatic species first described by Schmidt, which I find to be world-wide in dis ­ tribution.

It may be remembered here that I have already described and illustrated a species of Chondrilla of a buff-colour from Port Jackson, under the name of C. austrediensis (‘Annals,’ 1873, vol. xii. p. 23, pl. i. figs. 10-15). In appearance and colour, besides growing over all bodies with which it comes in contact, this much resembles Halisarca australiensis , but here again the resemblance ceases, tor Chondrilla australiensis is corticate and possesses spicules; while C. australiensis not only differs from C. nucula, Sdt. , in colour, but slightly in spiculation also, as the genuine specimen of C. nucula, Sdt. , above mentioned in Mr. Wilson’s collection well demonstrates.
