LEl'ADIDJE. POLLICIPEDID^E. 223 



CONCHODERMA AURITA (Liniie). 



On ships' bottoms stranded on the Devonshire coast (Cap- 

 tain Browii) ; Plymouth (Biol. Lab.) ; Plymouth on ships' 

 bottoms ( T. V. Hodgson, iv. p. 175). Ships' bottoms, Fal- 

 mouth (Cocks). 



CONCHODERMA VIRGATA (Spengler). 



Ships'' bottoms at Falmotith (Cocks). 



The Cineras aurita Captain Brown found at Plymouth is 

 clearly referable to this species, which no doubt occasionally 

 is brought to the Devon and Cornish coasts, but neither this 

 nor the two preceding species are true natives. 



Fain. 2. ALEPADID.E. 



ALEPAS PARASITA, Sander Rang. 



Under the name Cineras parasita, Cocks writes : rt Attached 

 to the umbrella of Cyancea tuljerculata ; " and Darwin writes : 

 " Mr. Cocks informs me that an Aiepas, apparently A. para- 

 sita, has been cast on shore near Falmouth attached to a 

 Cyansea ; and that two other specimens adhered to the 

 bottom of a vessel arriving at that port from Odessa " (Darwin, 

 The Lepadida3, p. 159). It is recorded from Loire-Inferieure 

 by M. Cailliaud.

SCALPELLUM VULGARE, Leach. 



Common off Start Bay, Plymouth and Falmouth, attached 

 to Hydroids (Tululana, Xt-rtidaria, &c.) (A. M. X.). 



POLLICIPES CORNUCOPIA, Leach. 



Montagu (Test. Brit. vol. iii. p. 7) \\ as assured by Mr.Laskey 

 that he observed the species on the bottom of a vessel that 

 had been upset and towed into Dartmouth, mixed with 

 L. anatifera and ansiferina, which completely covered the 

 lower part of the vessel. We ( A. M. A T .) have found it living 

 in great abundance on the shore at Santander in North Spain, 

 and Paul Fischer records it from La Gironde as found on all 

 the rocky coasts. The most northern locality which Darwin 

 gave was Portugal.
