SCIENCE-GOSSIP. 



Length. Male 1.6 mm. 



Cephalo-thorax pale yellowish-brown. Legs 

 brown, tinged with red. Abdomen dull brown, 

 with a greenish tinge. A rare species, but apparently 

 widely distributed. 



Gongylidiellum vivum Cb. (Neriene viva 

 in " Spiders of Dorset.") 



Length. Male 1.7 mm., female 2 mm. 



Cephalo-thorax brownish-yellow. Legs of a paler 

 tint than the cephalo-thorax. Abdomen yellowish- 

 brown, tinged with green. Each falx with a small 

 tooth-like process towards its extremity in front. 



I have received this rare spider from Mr. W. 

 Falconer, of Slaithwaite, and have taken it in 

 Epping Forest. 



Gongylidiellum murcidum Sim. 



The form of the palpi will be the surest clue to the 

 identity of this rare species. The radial joint is 

 furnished with a prominent, obtuse apophysis. 



G-ongylidiellum dolosum Cb. {Neriene 

 dolosa in " Spiders of Dorset.") 



Length. Male 1.8 mm. 



Closely allied to G. vivum, but does not possess the 

 tooth-like process on the front of the falx. A very 

 rare species. 



GENUS G0NGYLID1UM MENGE. 



The spiders included in this genus differ from 

 those of Neriene by the anterior eyes being in an 

 almost straight line, and by the spines exceeding in 

 length the diameter of the joint upon which they 

 are placed. The genus is hardly a satisfactory one 

 as at present limited, but will be here adopted as 

 being sufficiently concise for ordinary purposes of 

 identification. 



G-ongylidium graminieolum Bl. {Neriene 

 .graminicola in " Spiders of Dorset.") 



Length. Male 2.5 mm., female 2.75 mm. 



Cephalo-thorax yellowish-brown, with a black 

 marginal line and usually some dark lines converging 

 towards the thoracic indentation. Legs yellow- 

 brown with a tinge of red. Abdomen black, with 

 sometimes a pale central band. The radial joint of 

 the male palpus has two large apophyses on its 

 upper side, and upon the fore part of each falx is a 

 rather prominent tooth. 



Gongylidium rufipes Sund. {Neriene ntfipes 

 in "Spiders of Dorset"; Neriene munda in "Spiders 

 ■of Great Britain and Ireland.") 



Length. Male 3 mm., female 3.25 mm. 



Cephalo-thorax reddish-brown, darkest at the 

 ■caput. Legs red. Abdomen almost black, with 

 sometimes a pale central band. The cubital joint of 

 the male palpus is of a curious swollen form. A rather 

 common spider. 



Length. Male 2.7 mm. 



Legs pale yellow. Abdomen black. Clypeus 

 half as high again as ocular area. Falces finely 

 striated on outer side, and each with a frontal tooth 

 bearing at its apex two hairs. A very rare spider. 



Gongylidium morum Cb. 



An extremely rare species described and figured in 

 " Annals of Scottish Natural History," 1894. 



Gongylidium fuscum Bl. {Neriene fusca in 

 " Spiders of Dorset," p. 574.) 



Length. Male 2 mm., female 2.25 mm. 



Cephalo-thorax yellowish-brown. Legs reddish- 

 yellow. Abdomen almost black, with sometimes a 

 pale central band The radial joint has a slight 

 projection, armed with two small points. Not un- 

 common.
