COELENTERATA. 
In the present part we can only give lists of the Hydroida 
and Aleyonaria, as the other sections of the Coelenterata, — 
viz., the Zoantharia, the Acalepha, and the Ctenophora have 
not yet been sufficiently worked, and the material at our 
disposal is not extensive enough to enable us to compile 
anything like complete lists of these groups. 
So far as the Hydroid Zoophytes are concerned, however, 
we have had plenty of material. They have always been a 
favourite group with marine zoologists, and have been 
studied in the Firth of Forth by successive generations 
of naturalists, who have frequently been rewarded by the 
discovery of species new to science. 
Professor Allman and Dr Strethill Wright, whose researches 
we have already referred to in the Introduction, have con- 
tributed largely to our knowledge of the Hydroids. The 
section of Dr Wright’s work most interesting to us, in con- 
nection with these lists, is his careful investigation of the 
more minute Zoophytes, among which he discovered so many 
new species—especially in the Athecata. Further work of 
the same description among the smaller Campanularians 
would almost certainly yield interesting and valuable results. 
The nomenclature and arrangement in the following list 
are those given in Hinck’s “ History of the British Hydroid 
Zoophytes,” from which we have in various ways derived the 
ereatest assistance. For many of our names and localities 
we are indebted, in addition to the last-mentioned work and 
Dr Wright’s papers, to Allman’s “ Gymnoblastic Hydroids,”
