on the same horizon being published in the Quart. Journ. of the 
Geological Society, and in the Annals and Magazine of Natural 
History. Previously to Mr. Vine's labours, very little was known 
respecting the fauna of the Wenlock Shales of Shropshire. The 
shales, about 22 tons, were originally washed by Mr. ^law, for the 
purpose of assisting the late Dr. Davidson in his illustration of the 
Upper Silurian Brachiopoda, the residue being handed over (about 
2^ cwts. of washed material), to Mr. Vine. After several years 
labour the author was able to describe and catalogue a fine series of 
Pol3^zoa and Annelida tubicola, many of which were new, and with 
the assistance of Prof. T. Rupert Jones, about 100 species of Ento- 
mostraca have been catalogued and illustrated in the Annals and 
Magazine of Natural History by Prof. Jones and Dr. HoU. These 
papers represent the work accomplished, but much still remains to be 
done ; other groups of fossil organisms are only partially catalogued 
in the first of these papers. 
In 1887 the same author contributed Xotes on Classifications of 
Polyzoa, new and old. To working students especially this is a most 
important contribution to scientific literature, as in it the author 
records all the varied attempts at classifying the Cyclostomata, from 
the time of Busk's Crag Polyzoa Monograph to the present. The 
author, however, limits himself in this paper, practically to the Cyclos- 
tomata of the various Mesozoic horizons. The number of new species 
and varieties described in these papers are given below, under the 
dates when published : — 
1883. Ptylopora Phillipsia, Vine. 
(Thamniscus dubius ? King). 
Far. carbonaria, Vine. 
Ichthyorachis sp.. Vine. 
Glauconome bipinnata ? Phill. (Vine).
