 contracted. 



A very young specimen was easily recognised as belonging to 

 this species, and had the galea similar to that of the full-grown 

 ones.

I have seen six specimens, one <$ and four $ , and a young 

 one from Scotland — Oban (Argyllshire) — taken by the Rev. 

 R. Godfrey. 



The Rev. O. P. Cambridge, as mentioned in the introduction, 

 has re-examined L. Koch's type of this species and has found the 

 galea. L. Koch evidently examined the animal with too small a 

 magnification. The Scottish animals agree well with L. Koch's 

 description, except that the femur is stated to be granulated only 

 on the inner and the lower side, while the Scottish specimens 

 are quite as strongly granulated on the upper side of the 

 femur. 



Obisium lubricum, L. Koch. 



I have examined one specimen from Greenwich (Kent), taken 

 by Mr. F. W. Wilson.
