locality and their appearance, these Sea-lions must be referred to 

 the species of the Auckland Islands, upon which Mr. J. W. Clarke, 

 F.Z.S., made his valuable communication in 1873 (see P. Z. S. 1873, 

 p. 750), and should be called Otaria hookeri. 



The largest male is nearly equal in bulk to our old male O.jubata, 

 but has much shorter front flippers and rather longer external ears.

 (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 Eclii- 

 noderms, 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 abun- 

 dantly found in tlie Eastern seas. Of the Asteroids, Linclia Icevi- 

 gata was exceedingly abundant, there being twenty exainples of 

 it, and one only of L. pacifca ; of these twenty examples, one 

 was four-rayed. Scy taster nova-caledonice 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 ; 1 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 but 

 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
