SALVAGES. 295 



This appears to be by far the rarest of the three Auriculas 

 which have been detected hitherto at the Salvages, — the few 

 examples which I have seen having been partly received from 

 the Baron Paiva, and partly separated by myself from a mass 

 of the 'var. 7. albescens'' of the A. cequalis which had been 

 obtained by him from those islands. The species may readily 

 be known from the latter by being considerably smaller and 

 less elongate-ovate (or more strictly fusiform), and by the upper 

 one of its two ventral plaits being so far reduced in dimen- 

 sions as to assume the form for the most part, of a minute 

 and isolated tubercle. Its colour too is darker than that of the 

 cequalis (at any rate as represented at the Salvages), — it 

 being of a pale reddish brown, with a more or less decided violet 

 tinge. So far as I have yet observed, its outer lip is wholly 

 unarmed, or free from denticles. I may just add, however, that 

 the examples of this shell from the Great Salvage (which I have 

 cited as reprenting a ' var. /3. scrobiculata ') are not quite so 

 dark and purpurascent, on the average, as the Madeiran ones ; 

 and they are likewise a trifle slenderer in outline, and when 

 young more glossy in surface ; but in everything important the 

 two phases are undistinguishable. 



Having given a diagnosis of the A. Watsoni in my notice of 

 it under the Madeiran Group, I need not do more than refer to 

 p. 269 of the present volume for any further particulars concern- 

 ing it.

 taceo- aut (interdum) subflavo-albida ; spira breviuscula, conica, 

 anfractibus 5^-6 planis, ultimo elongato, sutura, ssepius lacerata ; 

 apertura elongata, plicis 2 instructa, — sc. 1 magna intrante ven-

This appears to be a most abundant Auricula on the tide- 

 washed rocks at the Salvages, from the larger island of which it 

 has been obtained in profusion by the Baron Paiva ; but I am 

 not aware that it has been observed hitherto in any of the 

 other archipelagos. I am extremely doubtful however whether
