142 CATALOGUE OF THE ECHINODERMATA OF 



I have found this species to be rare amongst dredged, material, 

 but very common on some of the sandy portions of our coast. 

 Large numbers of the dead shells (denuded of spines) were seen 

 upon the north-east portion of Holy Island Sands ; doubtless in 

 a few fathoms water off this spot the living animals could be 

 taken. Strange to record, this very common Echinoderm is 

 amongst the rarest in my collection, as I have only two speci- 

 mens, both from the Northumberland coast. My dredgings 

 have been confined to deeper water, and more generally remu- 

 nerative ground than the usually barren "inshore" sandy ground 

 of our coast. 



2. Echinocardium ovatum (Leske). Rosy Heart-urchin. 



Spatangus ovatus, Leske ap Klein, p. 252. PI. XLIX., 

 figs. 12-13. 



Amphidotus roseus, Forbes. Brit. Starfishes (1841), 

 p. 194. 



Rather rare, J. A. 



Very common on our coast, it being rare indeed that the 

 dredge comes up from a suitable depth (fifteen to thirty-five 

 fathoms) without one or more specimens. In deep water we 

 frequently bring up large numbers at a single haul : probably it 

 does not take the hook, hence Mr. Alder's different experience. 



8. Echinocardium pennatifidum (Norman). PI. V., figs. 1-5. 



Amphidotus gibbosus, Barrett. Ann. Nat. Hist., 2nd 

 Series, Vol. XIX. (1857), p. 33. PI. VII., fig. 2. 



Echinocardium pennatifidum, Norman. Last report of 

 dredging among the Shetland Isles, Brit. Ass. Report, 

 p. 315, 1868. 



In 1864 I dredged a fine specimen of this species in Berwick 

 Bay, which was recorded in the dredging report of that year. 

 I believe it is the only one that has been taken on the north-east 

 coast. It was whilst examining this specimen that Mr. Nor- 

 man detected the difference of character between E. gibbosus
