t, the only brokenrays being the seventh and ninth. The membrane of thefin was very little damaged, and by floating the whole crestout in a dish of water, its characters could be perfectly well ascer-tained. I find that in all essential respects the crest of the OtagoHarbour specimen (fig. 1) agrees with that of Cuvicrs figure ofE. gladius* in the illustrated edition of the Kegne Animal.It is distinctly divisible into two portions or nuchal fins, ananterior consisting of five, and a posterior of nine rays ; so thatthe total number of rays in the crest is fourteen. In my formerpaper I gave the number conjecturally as fifteen, stating thatwhat I took to be the last six rays were broken ; judging fromthe present specimen, it must have been the last five rays of thecrest and the first of the second dorsal which were damaged.Cuviers figure shows live rays in the anterior, seven in theposterior division. * lieprcnluced in 7, plate xxiv. nmsMjtmns Ifsm Jlttfbtijfr Jttstitate, Vol. xx. pi. v.
