LIST OF HYDROID ZOOPHYTES FROM THE NORTH-EAST 

 COAST OF SCOTLAND. 



The following list of Hydroid Zoophytes has been made up from specimens 

 collected on the north east coast, from the town of Peterhead to the Sands of 

 Cruden, and from a point about three miles north of the river Don to several 

 miles south of the mouth of the river Dee. Part of this extent of coast is sandy, 

 but the greater part is rocky. 



For the notice of the occurrence of many of the species I am indebted to the 

 kindness of the Rev. J. Yuil of Peterhead. 



I have followed the nomenclature of Hincks.
