FAUNA OF THE OUTER WESTERN AREA OF THE CHANNEL. 361 



latter, and such as presented no difficulty, were then worked out and 

 added to the list. Subsequently Miss Alice Heath kindly undertook 

 to identify the more doubtful or difficult material that remained. In 

 consequence of this, many of the species are absent from her list. 

 Eecords by Miss Heath are distinguished by the letter H. The 

 others, for which I am responsible, are followed by the letter C. Miss 

 Heath writes the following note on the specimens submitted to her : — 

 " The greater part of the material sent to me for identification was 

 in a dry state ; the remainder was preserved in alcohol. There proved 

 to be 30 genera and 54 species. Twenty-one species are recorded from 

 one station only. The classification and names given are those used in 

 the Plymouth Fauna List {Journ. Mar. Biol. Assoc, N.S., Vol. VII, 

 p. 155). Lc23ralia foliosa was represented by only one small piece 

 worked up into a worm tube. In Meiiibranipora fiustroides the zooecia 

 fitted rather more closely together, were less oval than in Hincks's 

 illustration, and the spines were represented by three only. On one 

 small zooecium these spines were flattened and glossy ; the others were 

 lost, their points of attachment only showing. One species of Alcyoni- 

 dium I have not been able to identify. Zoarium, erect, delicate, trans- 

 parent, flattened, about 2J cm. in height by 1 cm. in breadth ; attached 

 to a piece of Pecten shell ; not as firm and opaque as either A. gcla- 

 tinosum or A. mytili. Surface smooth. The superficial boundaries of 

 the zooecia could be distinguished, but very littlt of other details. 

 Brown bodies apparently occupied the interior."
