LINCOLNSHIRE FRESH-WATER MITES. 



C. F. GEORGE, M.R.C.S. 

 Kirton-in-L indsey. 



In former papers in ' The Naturalist/ I have recorded eight 

 species of Curvipes as found in Lincolnshire. I now wish to 

 increase that number by additional nine, as follows :— 



1. Curvipes rotundus (Kramer.) 



2. ., alatus (Sig. Thor.) 



3. fallax (Karl Thon.) 

 discrepans (Koenike.) 

 nodatus imminutits (Piersig.) 

 circularis (Piersig.) 

 paiiciporus (Sig. Thor.) 

 elegans (Soar.) 

 imcatiis (Koenike.) 



These mites, with a few others have been well figured and 

 described by Mr. Soar, in a paper published in the ' Transac- 

 tions of the Edinburgh Field Naturalists' and Microscopical 

 Society,' Session 1906-1907. Mr. Soar discards the old name 

 ' Curvipes,' and uses ' Piona,' a name applied to these mites 

 by the late Professor Piersig, of Annaberg, Germany. I 

 should advise all British Students of Water Mites to obtain and 

 study this capital essay. 



Arrhenurus nonforpicatus. — A Correction. — In the 

 ' Naturalist ' for 1903, p. 252, I described as a new water mite 

 Arrhenurus nonforpicatus. Since that time I have found two 

 more specimens, and doubting whether they were mature, I 

 kept them one month and two days, when one of them died 

 (the other I killed for mounting). During this time develop- 

 ment had proceeded far enough to satisfy me that they were 

 really specimens of Arrhenurus forpicatus. Nonforpicatus must 

 therefore be deleted from the list, or simply used as a synonym 

 or to indicate a certain stage of growth of A. forpicatus. 



Northampton and its Surroundings, by S. S. Campion, J. P. The 



Homeland Association, 22, Bride Lane, Fleet Street, E.C. 112 pp., 6d. 



This is a well-written and well-illustrated handbook to Northampton, 

 and with it the visitor can easily see what is worth seeing. There is also 

 a good plan. From the title page we learn that there are ' Notes on the 

 Geology of the District,' by Beeby Thompson ; on the ' Botany of the 

 District,' by H. N. Dixon, and on the ' Ornithology of the District,' by Rev. 

 W. A. Shaw. As, however, these articles only occupy one small page each, 

 they might almost as well have been omitt^ \
