LTJHPENUS LAMPETRIFORMIS OK THE COAST OP SCOTLAND. 45 
Ophiotbrix pentaphyllum. Here and there very sparingly dis- 
tributed is also to be found that link which joins the present to 
the past — our elegant British Crinoid, Antedon rosacea. 
From the depths of this vast aquarium we also sometimes 
obtain a specimen of that fine, but most repulsively odoured 
Starfish, Sticliaster roseus, accompanied occasionally by Palmipes 
membranaceus. 
Here also is that form which the late Prof. Porbes calls one of 
the rarest and most beautiful of our native Starfish, PLippasteria 
plana ; beautiful it unquestionably is ; but in this long valley 
it is by no means rare, dozens are sometimes brought up at one 
drag of the net. Accompanying it, but in very much fewer 
numbers, is its exquisitely coloured little brother, Porania pul- 
villus. And yet again, along this great expanse of mud, sand, 
and peat, live Astropecten irregularis and Luiclia Savignyi, the 
latter a form more troublesome and tantalizing in its habits 
than any of our Starfish with which the lover of Nature may 
come in contact. Hundreds of this fine form are brought up 
both by trawl and line, but only to fall in pieces on coming to the 
surface, or, as Porbes says, “ in a minute he proceeds to dissolve 
his corporation.” 
Of the Echinoidea which frequent this ground, we have Bchino- 
cyamus pusillus, Spatangus purpwreus, Brissopsis lyrifera, and 
Bcliinocardium cor datum, while in each suitable resting-place are 
specimens of Priapulus caudatus , a favourite food of the “ Witch- 
Sole.” Aphrodita aculeata is also present in abundance. 
The Crustacea to be met with along these grounds are numerous 
and highly interesting. Heading the list comes Cancer pa gurus, 
Lithodes maia, Nephrops norvegicus , Corystes cassivelaunus , Calo- 
caris Macandrece (the latter is eaten in euormous numbers by the 
Witch-Sole), Galathea squamifera , G. dispersa , and G. Andrewsi, 
Pagurus Bernhardus, P. Tliompsoni, and P . Prideauxi (always 
accompanied by its humbler friend Adamsia palliata), Portunus 
liolsatus, P. pusillus, and P. depurator, Crangon vulgaris, C. bispi- 
nosus, and C.trispinosus, PLippolyte spinus, Callianassa subterranea. 
Pandalus annulicornis , various species of the genus Diasiylus, 
accompanied by their kindred form Budora truncatula, and 
several of the Mysidse literally swarm. These are all the higher 
Stalk-eyed Crustacea; but in addition to the above list there is 
another stalk-eyed form, of which I have taken several specimens
