RADIATA.

CENTRONIA.

1. Echinus ovum ? Peron and Lesueur. Lam. Hist. 3 48.

This specimen, presented to the Museum, agrees very well with the short description given by Lamarck of this species.

2. Echinus variolaris. Lam. Hist. 3 47.

This specimen, agreeing very well with the description of one found by Peron, is very remarkable; and has the larger area agrulate and ornamented with two rows of white tubercles, nearly as large as those in the genus Cidaris; the pores in the upper part are not perforated, and are placed in segments of circles round small tubercles.

3. Echinometra lucunter.
Echinus lucunter. Gmel. Sys. Nat. 1 3176.
Icon. Ency. Method. t. 134. f. 3, 4, 7.

ANOMALIA.

Physalia megalista ? Peron Voyage 1 Lam. Hist. 2 481.
Icon. Peron, Voyage Atlas, t. 29. f. 1.

No specimen of this animal was preserved, but Captain King observes, that the animal he caught, of which he made a drawing, differed from Lesueur's figure of P. megalista, in being of smaller size, and with fewer tints; the colour of the tentacula was a brighter purple tipped with yellow globules, and the crest of a greenish hue, but the general colour of the animal was purple. It measured from three-quarters to one inch in length. Captain King considered it to be a variety of P. megalista.
