Report on the zoological collections made in the Indo-Pacific Ocean ...

ECHINODERMATA. 119Echinoidea," I directed attention to the marked discrepancies whichobtained between the descriptions given by Louis and AlexanderAgassiz respectively of the species known as JS. globator. I thenfigured and gave careful descriptions of the tests of two formswhich I distinguished as form a and form /3. I adopted that coursein the hope that Prof. Alexander Agassiz would explain the reasonswhich had led him to omit any notice of the species referred to byhis father. In the 'Challenger' lieport the species is merelyrecorded, and reference made to the ' Catal. Eaisonne' of Agassiz andDesor ; fortunately the specimens are uow in the liritish Museumcollection, and an inspection of them is,the characters of the form which Mr. Alex. Agassiz looks upon asbeing S. globator. I lind them to be examples of what I haveof course, siifficient to showcalled form a, or, in other words, they are not representatives ofL. Agassiz's species gJohator.As the species reappears in the ' Alert ' collection, it has beennecessary to direct attention to the various points and to proposea name for the species. No appellation will, I think, be more suitablethan that of alexandri ; and, at the time of giving a definitename, one is also able to have the pleasure of adding a definitelocality.West Island, Prince of Wales Channel.(j.Temnopleurus toreumaticus.A.

Ac/assiz, ' Challenger ' Pep. iii. p. 108.This is one of the most important of Dr. Coppinger's finds, forwith the exception of a single, though perfect, test in the collectionof the British Museum, which was obtained by 8ir E. Belcher offBorneo, and presented by the Admiralty in 1844, no completeexample had ever been examined till the return of the Challenger.''The largest specimen taken by Dr. Coppinger is a little larger than
