It was pointed out that, while the birds and egfgfS included 

 ii:^ the lists now approved would be protected in all the thre,e 

 Riding-s alike, as was desired by the Naturalists' Union, , yet 

 there will be other birds and eggs included in the more com- 

 prehensive list approved by the Home Secretary as applicable 

 to the West Riding-. W. H. St. Quintin, Chairman.' 



The result of the petition must be met with approval by all 

 Yorkshire Naturalists. - 



It is also pleasing to report that, in response to £\ request 

 from the Union, the Bridlington Harbour Commissioners have 

 given orders for the discontinuance of the practice of firing 

 guns or rockets at the birds on Bempton and Speeton Cliffs 

 from the pleasure steamers sailing from Bridlington. A similar 

 request previously made to the Scarborough Harbour Commis- 

 sioners by the President of the Yorkshire Wild Birds Protection 

 (Mr. T. ,H. Nelson) has also been complied with. T. S. 







LINCOLNSHIRE FRESHWATER MITES. 



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



Arrhenurus mollis, n.sp. — I have met with a mite, on 

 more than one occasion, which possesses the peculiar palpi 

 belonging to the genus Arrhenurus ; the legs, epimera, and 

 acetabular and genital plates, are also similar to a female 

 Arrhenurus. It, however, differs in having the body skin soft 

 and lined, without any chitinous layer, and without any appear- 

 ance of the curved depressed line, which is so marked a feature 

 on the dorsum of mites of this genus. 

 Fig. I is an outline figure of the dorsum 

 showing its general appearance. It is seen 

 to be almost circular. The creature, how- 

 ever, when alive seemed to me to be rather 

 more octagonal than the , figure indicates. 

 Any slight pressure, such as might be used 

 to keep ,the creature in one position whilst 

 drawing proceeded, would, of course, cause 

 a soft-bodied mite to assume a more or less 

 .circular form. It has a number of fine hairs 

 on the dorsum, and especially at the posterior 

 part, some of which are very long, and 

 similar to thpse which are found on most female nymphs of this
