are small, and that the known adults of the genus are large ; it is safe, therefore, 

 to conclude that this specific name may l)e made a synonym 



Mr. Hodgson collected some quite young exam2)lcs chiefly in W.Q., and, with 

 the specimens sent l)y the Government Biologist at the Cape of Good Hope, we 

 have now a very satisfactory series ; it was also taken at McMurdo Bay, 9G-100 fms. 



Cycethra verrucosa. 

 (Plate v., fig. 1.) 



Gnnmlisrus vernirosiis, Philippi, Arch. f. Nat. 1857, p. 132, /estn Mei.ssner, ZooL Anz. xsi. (1898), p. 39-t. 

 Cycethra simpler, Boll, Proc. Zool. Soc. 1881, p. 96 ; id. Coll. 'Southern Cross,' 1902, p. 215 ibique citata. 



I was much to blame for neglecting or forgetting, in 1902, Dr. Meissner's very 

 useful note ; the alteration of the name is not, of course, of the least importance to any 

 sensildc Imiiian lieing, but the knowledge that the species extends nearly as far north 

 as Valparaiso is of great interest and significance, for it shows us that the distribution 

 is far wider than we supposed ; had Dr. Leipolt (Zeit. f. wiss. Zool. lix. (1895) p. 602) 

 known of it, he would have spoken with less point than he did, when he doubted 

 Prof. Studer's locality of 38° 10' S. 



The variations of this species are truly bewildering; I have had an extreme form 

 figured, and offer a slight account of it ; it was long before I could convince myself 

 that it is C. verrucosa, and I am doubtful as to convincing others. 



The upper surface is uniforndy covered by delicate spines which end in a few, not 

 more than ten, paxilli ; the space between these spines is soft and membranous ; the 

 lower surface is densely covered with spines of moderate length and sharp at the tip ; 

 the spines bordering the ambulacral grooves are somewhat irregularly arranged, 1)ut are 

 longer and lilunter than those that crowd the interambulacral spaces; there is a 

 single glossy spine at each angle of the mouth. The two rows of marginal plates are 

 well defined, and the paxilli are somewhat longer and more numerous than those on the 

 up])er surface of the body. The madreporite is very prominent and is not far from 

 the centre ; close to this last there is a small tuft of white spines which, T suppose, 

 guard the anus. Colour, light creamy yellow ; body flat ; i? = 55 ; r = '20. 



Examples were taken on various dates at Winter Quarters ; off Castle Rock, 

 14 fms. ; Cape Wadsworth ; Coulman Lsland ; McMurdo Bay, 20 fms. It does not 

 appear to inhabit deep water. 



Henricia ornata. 



EcUnaster {Cribella) ornatus, Perrier, Ann. Sci. Niit. xil. (18f;9), p. 251. 

 Henricia ornata, Bell, Mar. Invert. S. .Vfiicn, iii., (1905) p. 250. 



//. ornata is recorded by Sladen from Campbell Island ; his //. simpler, wliich 

 is a syuouym, was taken olf the Crozets, Maricm Island, etc. 



One specimen was obtained off' Coulman Island, 100 fms. ; one from 4-10 fms. 

 McMurdo Bay ; and three from 9G-120 fms., in the same bay.
