R.M.S., Professor of Comparative Anatomy and Zoology in King's College, London. [Eeceived January 18, 1887.] (Plate XVI.) Dr. John Anderson, F.R.S., Superintendent of the Indian Museum, Calcutta, was lately kind enough to excite the interest of Col. Cadell, V.C., in the marine zoology of the Andaman Islands, which are at present under his charge, and to present to the British Museum the collections thus made. The following contains a report on the Echinoderms, which Dr. Anderson has asked me to draw up. The condition in which the specimens reached England reflects great credit on Mr. Booley, who made the collections for Dr. Anderson. There are in all fifty species of Echinoderms, of which no less than twenty-two are Holothurians ; the bulk of what follows will treat chiefly of these interesting but difficult forms, which are abundantly found in the Eastern seas. Of the Asteroids, Linckia lavi-gata was exceedingly abundant, there being twenty examples of it, and one only of L. pacifica ; of these twenty examples, one was four-rayed. Scytaster nova-caledonia was not rare ; Culcita was represented by handsome species. Of two of the most difficult genera, Linckia, Astropecten, there is in each case a single example of a form unknown to me ; I cannot associate either with a described congeneric form, but, on the other hand, I am not satisfied that they are the representatives of " new species." Among Ophiuroids, the only noteworthy point is the complete absence of Ophiothrix from the present collection. There is hut one Crinoid. It is to be regretted that it is impossible for me to compare the results of a collection at Mergui with that now before me, my report on the Holothurians collected by Dr. Anderson being as yet the only portion of the account of Echinoderms which has appeared in the |
