Sample 3. — Off Ardnamurchan, 20 fms., shell-bank. 



2,300 c.c. of brown shell and coral debris. 1,300 c.c. 

 passed the 1/10 sieve and were examined. 128 species. 



Coarsest siftings rich in gigantic specimens. Noteworthy 

 species Gypsina vesicularis, Polymorphina compressa (see fig. 13). 



Finer siftings rich in small arenaceous forms, notably 

 Ammodiscus incertus, Trochammina rotaliformis, Haplophrag- 

 mium moniliforme and (?) findens (see fig. 12).

♦Note. — It must be borne in mind that the following list is a purely 

 preliminary and provisional one. It has been compiled from the notes 

 made during the first examination of the material from Stations [-IV, and is 

 intended merely to serve as an indication of the general character of the 

 dredgings. There are several species recorded which are new to Great 

 Britain, and several, the affinities and specific determination of which are 

 given subject to revision and correction when the whole of the samples have 

 been examined and compared. H-A. and E.
