CHAP. II.] THE CRUISE OF THE ' LI6HTNING.' 63 



appropriately close these chapters, I now dedicate 

 this volume, in remembrance of the great kindness 

 which we invariably experienced from her and from 

 her excellent husband. 



We lay in Thorshavn harbour till the 26th of 

 August, the weather being so bad as to make all idea 

 of pursuing our work outside hopeless. Whenever it 

 was possible we dredged in the fiords with Tseroese 

 boats and native boatmen, and we made the acquaint- 

 ance of Sysselman Mtiller, the representative of Fseroe 

 in the Danish Parliament, who had made himself 

 thoroughly conversant with the moUusca of Fseroe, 

 and had contributed his information to a list published 

 in 1867 by Dr. O. A. L. Morch. The shallow-water 

 fauna seems to be scanty, as we find frequently to be 

 the case on a bed of decomposing trap. It is of a 

 character intermediate between that of Shetland and 

 the Scandinavian coast. The forms which perhaps 

 interested us most were Fusus despechis, L. — a hand- 

 some shell which may possibly be only a very marked 

 variety of Fusus antiquus, L. ; but if so, it is one with 

 very definite limit of distribution, as it occurs only 

 rarely in very deep water in the British seas. In water 

 of moderate depth among the Pseroes it is abundant, 

 apparently replacing F. antiquus. Another common 

 Taeroe shell is Tellina calcarea, Chemnitz, — a very 

 abundant British glacial clay fossil, but not hitherto 

 found recent in the British area. In the glacial clays 

 near E-othesay it is in regular beds associated with 

 My a truncata, L , var. uddevallensis, IFobbes ; Saxi- 

 cava norvegica, Sprengleb; Fecten islandicus, 0. F.

 so fresh that the two valves are still in position and
