description or appending to it any distinctive name. There can be 
no hesitation therefore in associating the fossil with the existing 
genus, and it may not be inappropriate to append the name of 
Mr. Lawley and distinguish it specifically, Chlamydoselachus lawleyi. 
The figures will be found in " Nuovi Studi sopra ai Pesci ed altri 
Vertibrati fossili delle colline Toscane," di Roberto Lawley, published 
at Florence in 1876, pi. i. figs. I am indebted to Mr. G. A. 
Boulenger for the opportunity of comparing them with the teeth of 
the recent Ghlam'/dosehchus in the British Museum. 
NOTES ox THE DISTRIBUTION OF THE ENTOMOSTRACA IN THE WENLOCK 
SHALES. MR. MAW's WASHINGS. BY GEORGE ROBERT VINE. 
PART I. — BUILDWAS BEDS. 
In the proceedings of the Yorkshire Geological and Polytechnic 
Society of last year/'' I gave a paper on the Palaeontology of the 
Wenlock shales of Shropshire, together with a list of species found 
in the now celebrated washings of Mr. ]\Iaw. Originally these 
shales, over twenty tons, were washed, for the purpose of selecting 
the Brachiopoda fi'om the remaining delris, to help the late 
Dr. Davidson in his descriptive work on this group of organic forms. 
In the paper refeiTed to I also gave full descriptions of the various 
horizons of the Wenlock shales, so far as supplied me by Mr. Maw, 
both below and above the Wenlock limestone. At the time I wrote 
the list was unavoidably incomplete as the Ostracoda not having 
been fully described by Messrs. Jones and Holi, the specific names had 
to be filled in from ^IS. notes furnished to me, subject to alterations, 
by Professor T. Rupert Jones himself. The notes on the Ostracoda 
of the shales now given, treat of the published descriptions of Messrs. 
Jones and the late much-lamented Dr. Holl. During the progress 
of the British papers. Prof. T. R. Jones received for examination 
in 1886 " A fine series of Ostracoda from the Silurian rocks of Goth- 
land," supplied by Prof. G. Lindstrom, of the State museum, 
Stockholm. As many of the species in the Gothland list belong to 
* New series, vol. ix., pi. ii., pp. 224 — 248.
