Tmeticus Jiirjcr, F. P. Cambr. Ann. and Mag., jS".1T. 1891, vol. 

 vii., p. 80, pi. ii., f. iv. 



Porrliomma nigrum, Cambr. Proc. Dors. N.H. and A.F, Club, 

 1891, vol. xii., p. 92. 



Subsequent examination proves tlie identity of Neriene rudis, 

 Cambr., with Tmeticus niger, F. P. Camb. 



PORRHOMMA MIOROPHTHALMA. 



Linyphia microphtlialma, Cambr. Spid. Dors., p. 523. 

 ,, incerta, Cambr., 1 c, p. 205. 

 „ decens, Cambr., I.e., p. 217. 



Porrliomma Meadii, F. P. Cambr. Ann. and Mag., N.H., 1894, 

 ser. 6, vol. xiii., p. 101, pi. II., fig. 2. 



Careful microscopic examination and comparison appear to show 

 that the above are identical species. It has been found at Blox- 

 worth, as well as at Hoddesdon (in Hertfordshire), and near 

 Durham. An ordinary lens is not sufficient for the certain deter- 

 mination of these, and many other minute and closely allied 

 spiders. 



PORRHOMMA OBLONGUM. 



Linyphia oUonga, Cambr. Spid. Dors., p. 204. 



Porrliomma ohJongiim, Cambr. F. P. Cambr., Ann. and Mag., 

 N.H., sec. 6, vol. xiii., p. 102, pi. II., f. 4. 



The types of this small spider (adult females only) were found 

 running on iron railings at Bloxworth many years ago. Numerous 

 females and one adult male were subsequently found at Hoddesdon 

 by Mr. F. M. Campbell on railings and among grass, and in June, 

 1893, I met with both sexes in the adult state not uiifrcqucntly 

 among herbage in a wood at Bloxworth.
