to g-ive me the localities of his shales, but this I have never received ; 
but in one of his letters, he says that his best locality was about 
ten miles from Richmond ; but there were other localities, though 
not so rich in org-anic forms, which he promised to search for me. 
Had he lived, we should have worked together, as he promised me 
that I should have the material properly labled. As it is, my box 
of black muddy shale washings are marked only " Hurst," Rich- 
mond, a locality that I can give no other information of than this 
respecting it.* If, therefore, my northern friends would do their 
best to communicate to me the whereabouts of these shales, I shall 
be glad to give in return for their interest in my studies, something 
at least of corresponding value to assist them in theirs. Besides 
the shales, I have a few mounted forms given to me by way of 
exchange, and these are marked " Downholm " and "Ten Fathom 
Grit." These are some of the rarer species, specimens of which, 
however, are found also in the shales marked " Hurst." In Prof. 
T. Rupert Jones and Mr. James W. Kirkby's paper on Palceozoic 
Bivalved Entomostraca^ No. VII., Ann. and Mag. of Nat. Hist.^ 
July, 1866 ; the authors (p. 9) speak of a collection submitted to them 
by Mr. J. H. Barrow, M.A., of Settle, Yorkshire. I do not know 
the extent of that collection, and I am not aware that there are any 
more extensive references to the Carboniferous Ostracoda of North 
Yorkshire than are found in the various Carboniferous papers of these 
authors. In T. Rupert Jones' paper on the Permian Ostracoda 
( Perm. Foss., by W. King, pp. 58-66), references are made to find- 
ings in the Yorkshire Permian rocks ; and in Mr. T. Kirkby's paper 
on the Permian Beds of South Yorkshire (Quart. Jour. Geol. Soc, 
March, 1865), the author refers to five species of Entomostraca 
found in the Shell Limestone, and in his remarks on the Permian 
fauna, Mr. Kirkby says, that four of the Entomostraca are German, 
and one, Kirhhya Permiana, J. and K. have Russian varieties. 
Since these papers were written, the ranges of several of the Per- 
mian forms are proved to be Carboniferous " recurrents," and our 
knowledge of the range in Carboniferous times of some of the
