References. Alexander Agassiz, Revision of Echini, pt. 3, 1873, p. 575. Alexander Agassiz, ' Challenger ' Reports, vol. iii. Echinoidea, 1880, p. 175. R. Koehler, M e m . Soc. Zool. de France, t. viii. 1895. Locality. A single damaged specimen from 4 fathoms on mud. Singapore. Distribution. Recorded from the Red Sea and Cape of Good Hope to the Philippines; it extends also into North and West Australia, and according to Agassiz it is found in the Gulf of California. There is some doubt as to whether this species is correctly determined, on account of the broken condition of the posterior end of the test; but the arrangement of the long serrated abactinal spines and the shape of the actinostome resemble those parts in L. elongata more than in L. subcarinata, the only species with which it could be confounded : the colour also is characteristic of L. elongata, the large spines being yellow banded with violet as in the type. 15.

Extends from the Red Sea to Sandwich Is. in the Fndo-Pacific circumtropical littoral region ; it is also recorded from Australia and N e w Zealand. It is at once distinguished from Brissus carinatus by its cordi-form subanal fasciole, narrower actinal plastron, and deep anterior groove. Measurements. Length. Trans, diam. Ant, petal. Post, petal.
