THE HARVESTMEN. 
The late Dr. R. H. Meade, of Bradford, was one of the first 
English naturalists of note to study harvestmen, and from his 
pen there appeared in the Ann. and Mag. of Nat. History, 
series 2, vol. XV., pp. 393-416, in the year 1855, a ‘ Monograph 
on the British Species of Phalangiidz or Harvestmen,’ which 
he afterwards (in 1861) supplemented with a short paper in 
the same journal, Series 3, Vol. VII. Of his sixteen species, one 
has since been disallowed, while another is doubtful and may 
be deleted. In 18g0, the Rev. O. Pickard Cambridge published 
his standard ‘ Monograph of the British Phalangidea or Har- 
vestmen.’ in the ‘ Proc. Dorset Nat. Hist. and Antiq. Field 
Club,’ Vol. XI., in which he described and figured twenty-four 
species. One of these, Platybunus triangularis Herbst., is now 
generally recognised as the immature form of P. corniger Herm., 
and it is the opinion of Professor Kulezynski* that Sclerosoma 
vomanum LL. Koch, bears a similar relationship to S. quad- 
ridentatum Cuv., (the Rev. O. P. Cambridge does not subscribe 
to this ruling), and Oligolophus cinerascens C. Koch. to O. 
alpinus Herbst., which is itself merely an alpine form of O. 
morio Fabr., so that the above total will be correspondingly 
still further reduced. The last addition to the British list 
was recorded by Mr. Cambridge in the ‘ Proc. Dorset Field 
Club, 1907.’ Thus twenty species occur in the British Isles, 
and of these fifteen and one variety have been met with in 
Yorkshire, nine being recorded in the above-named works, 
one in the ‘ Trans. of the Hull Scientific and Field Naturalists’ 
Club, 1908,’ and the rest in a paper by the writer, 1906. In 
1907, the harvestmen of the county as then known with sum- 
mary of localities, were noted in the Victoria County History
