Hub. Palestine and Asia Minor. Type from near 

 Jerusalem. 



Type. Adult female with worn teeth. B.M. no. 18. 8. 1. 2. 

 Collected May 1918 durin^- ihc British campaign, and |)re- 

 sented by Capt. Guy C. Shortridge. 



Of this liedgeliofj the ]\Iusouin contains five specimen^, 

 with imperfect skulls, from Mt. Lebanon, presented by 

 Saleem Baroody, a fine old female from Tortoum near 

 Erzeroum, collected by R. B. Woosnara, and another from 

 Kara Dagh near Konia, presented by L. Ramsay, in addition 

 to the present specimen (the type). I have thought it wise 

 to select as type a specimen from the farthest soutliern 

 known extension of the group — that is, of the restricted genus 

 Erinaceus, — the hedgehogs from further south and east being- 

 referable to Heiniechinus. 



XXIII. — Onaneio Jumping Mile, of tlia Genus Nanorchestes 

 from the Mendip Hills. By STANLEY HiKST. 



The mite dealt with in the present note is of interest, owing 

 to the fact that the only species of the genus hitherto 

 described (viz. Nanorcliastes amphibius, Topsent & Troues- 

 sart) lives on the sea-shore, between the tide limits or 

 sliglitly above them. This littoral species was discovered by 

 M. Topsent at Luc-sur-Mer (Calvados), France, and after- 

 wards found by the author at St. Catherine's Point, Isle of 

 Wight. The new species described below lias a very 

 different habitat. Cor it lives on the summit of tiie Mendip 

 Hills at an jiltitude of over 800 feet and more than eight 



miles from the sea-coast.

General appearance very like N. ampkibius, Tops. & 

 Troness., but smaller in size. Hairs on dorsal surface of 

 cephalothorax also very similar. The. curious unpaired 

 median structure between the chelicerai is present and 

 strongly curved. This new species differs from JV. ampkibius 

 in the following details of structure : — Dorsal hair on cheli- 

 cera slender and dividing close to the base into two plumose 

 branches, the outer one being considerably longer than the
