SOME POLYZOA, ETC., 

 OF THE CUMBERLAND COAST. 



S. LISTER PETTY, 



Ulverston, North Lancashire. 



As the following- is, I believe, the first list of its kind for 

 Cumberland, its fragmentary state must to some extent be 

 accounted for as a preliminary examination of a somewhat 

 difficult coast line to work. The railways have not been 

 arranged for the convenience of a natural history worker who 

 resides outside the county. While staying- at Silloth the rain 

 came down every day and most of the day, and only two small, 

 and by no means select, gatherings were obtained. Weeds 

 were scarce, and none of the material was too clean. 



As an example of the difficulty which occasionally presents 

 itself in naming the host species, one clump of Tubularia 

 indivisa L. had many of its tubes incrusted by Membranipora 

 pilosa ; some were covered by growths of Scrupocellaria reptans, 

 amongst which was S. scruposa, Bugula flabellata, and Sertu- 

 larella poly somas. 



My thanks are due to Miss Allen, of Ulverston, for specimens 

 from Bootle, and to Mr. Joseph Parkinson for the Hodbarrow 

 gathering from a mussel ground at a depth of 20 feet at low 

 water. Hodbarrow is near Millom. Specimens have been 

 forwarded to Mr. W. Hodgson, A.L. S., of Workington. A few 

 bits I have mounted for preservation. Names and order as in 

 Dr. Hincks' books.
