Genus— TRICHONISCOIDES, Sars, 1898 



(59), p. 164. 

 A bdomen narrow ; eyes simple ; (ov wanting) ; 

 flagellum, with four joints. 

 The members of this genus are very much 

 like those of Trichoniscus. In the latter, how- 

 ever, the hinder legs are longer in proportion 

 and the eyes are compound.

We are able to include this species, as a 

 specimen was found by Mr. Webb at Eton 

 Wick in the summer of 1898. It is one of 

 a number of species which the Rev. Canon 

 Norman (49, p. 18) suggested as likely to be 

 British. It is the only representative of its 

 genus, which does not differ in any very important characters 

 from the others in the family. The narrow elongated body will 

 serve to separate it from Trichoniscus vividus and Trichoniscus 

 roseus, but on account of its size, which is much the same as that 

 of Trichoniscus pusillus and the two British species of 

 Haplophthalmus, it will be advisable to give some further points 

 of distinction. From the first its white colour will serve to 

 differentiate it ; the other two lack the narrow abdomen seen in 

 Trichoniscoides albidus. Moreover, not one of the three shows the 

 serrations on the side plates which characterise the species under
