Mr Herdman on Invertebrate Fauna of Lanilash Bay. 193 



in Scotland much oftener than in the few instances which I 

 have given, but it is extremely difficult to obtain reliable 

 information on the subject, as the majority of gamekeepers 

 and shepherds, who have the most frequent opportunities 

 for observation, confound it with either the shieldrake or 

 merganser. 



In collecting the foregoing notes I have to express my 

 indebtedness to several gentlemen who have obligingly and 

 readily answered my questions with reference to the breed- 

 ing of this interesting bird, and especially to the Eev. Alex. 

 Stewart, The Manse, Ballachulish ; Mr Mackenzie, Dornoch ; 

 Mr Gray, etc., etc., as well as to Mr Malloch, naturalist, Perth, 

 and Mr Sim, naturalist, Aberdeen. I am also more than 

 obliged to Mr J. A. Harvie-Brown of Dunipace, for the extract 

 from his Egg Book, and for much other valuable assistance 

 and advice. 



IV. On the Invertebrate Fauna of Lamlash Bay. By 

 William Abbott Herdman, Esq., B.Sc. [Plate IV.] 



(Read 21st January 1880.) 



Lamlash Bay has probably been as much worked by the 

 naturalist's dredge as any other area of similar extent on the 

 coast of Scotland, yet the published lists of the animals found 

 in it are, as regards many groups, far from being exhaustive. 



Dr Landsborough, in his "Excursions to Arran" (1852), 

 gives a list of the Mollusca and Foraminifera which had been 

 found there by himself and others. 



A more complete marine fauna of the district is to be found 

 in Bryce's " Geology of Arran and Clydesdale." The lists 

 in this work were drawn up by Dr Miles, and include the 

 species dredged by Dr Landsborough and Major Martin, in 

 addition to those obtained by Dr Greville and Dr Miles him- 

 self, which latter constitute the list given in a paper published 

 in the British Association Report for 1856. These conjoined 

 lists were finally revised and supplemented by Dr Carpenter, 

 and appear in this their most complete form in the 4th edition 

 of Dr Bryce's work (1872). As far as regards the Mollusca and 

 EcTiinodermata, they are very full.
