3784 Radiata. 



others that are equally if not more rare. " It was first figured as Bri- 

 tish by Mr. Sowerby, in the ' British Miscellany,' from a specimen 

 'found by James Brodie, Esq., in February, 1806, on the coast near 

 Brodie House,' in the North of Scotland." 



The Butthorn, Asterias aurantiaca. Frequent. The fishermen say 

 that this star-fish is commonly found on " hard" ground, that is free 

 from shifting sands or mud. 



The Lingthorn, Luidia fragilissima. Both varieties have been met 

 with by the Rev. Jas. Weir, at Lossiemouth, when brought from the 

 fishing-ground by the boats. Perhaps no two varieties of any of the 

 Echinodermata at first sight look so like distinct species. They differ 

 in the number of the rays, and, so far as has been observed in this 

 district, in size and colour. This species has been found by Dr. Fle- 

 ming at Cromarty; Alex. Robertson, Esq., Woodside. Both varieties 

 have been obtained at Gamrie by Mr. Harris, (Zool. 3307). 



Common Egg Urchin, or Sea Egg, Echinus sphcera. Occasionally 

 found on the sea-rocks at low-water, as at the Stotfield Skerries, &c. 

 A frequent ornament on the mantel -piece. 



Purple-tipped Egg Urchin, Echinus miliaris. Abundant wherever 

 the shore is rocky. 



Green Pea Urchin, Echinocyamus pusillus. Frequent in the sto- 

 machs of haddocks, and occasionally found among shells on the sea- 

 beach. 



Purple Heart Urchin, Spatangus purpureus. Occasionally found 

 in the stomach of the haddock, but always in fragments. 



Common Heart Urchin, Amphidolus cordatus. " Skate's Eggs." 

 Frequently found on the beach ; and often filling the stomach of the 

 haddock, which seems to be partial to it in feeding. 



Rosy Heart Urchin, Amphidotus roseus. Rare. 



Angular Sea Cucumber, Cucumaria pentactes. Occasionally met 

 with. 



The Tailed Priapulus, Priapulus caudatus. Seems not uncommon 

 from the number seen in some fish, cod and haddock. The size and 

 some other particulars, not being the same in all, seem to indicate 

 more than one species of Priapulus in the Moray Firth. 



The two last species must be but a very small proportion of the 

 Holothuridae and Sipunculidae that inhabit the broad and deep waters 

 of this arm of the German Ocean. To be able to enumerate no more 

 from such a field, shows at least that little attention has as yet been 

 here paid to these tribes. In order, then, to assist in identifying such 

 forms as may afterwards come under notice, specimens of these two
