Mr. R. H. Meade on the British Species 0/ Phalangiidae. 355 



Phalangium minutum. 



When I published my monograph, the habitat of this minute 

 species was unknown to me : I had then seen but two specimens. 

 I have since found another, in a collection of Phalangiidae made 

 in the neighbourhood of Dublin. 



Genus Opilio, Herbst. 

 Opilio histrix. 



I am glad now to be able to give this fine Harvest-man (our 

 largest native species) a clear title to a place among the British 

 Phalangiidse. 



In November 1856, the Rev. A. M. Norman transmitted to 

 me, alive, a fine adult female specimen, which he found under a 

 mat " which lay before a window opening down to the ground into 

 the garden," at Kib worth, near Market- Harborough, Leicester- 

 shire. In November of the following year I had also the plea- 

 sure of receiving a pair (male and female) of the same spiders 

 from Mr. Norman, which were captured at Kibworth. In de- 

 termining the name of these specimens fi'om my description, it 

 struck this naturalist that a slight alteration in the account 

 would make it more correct : viz. that the row of minute teeth 

 with which the posterior edge of each ring of the abdomen is 

 said to be furnished should have been called a row of small 

 tubercles. 



Genus Leiobunus, Koch. 



Leiobunus Blackwallii, n. sp. 



L. forma et colore Leiobuno rotundo consimilis ; sed differt cephalo- 

 thoracis fronte pallida, corneis albo cinctis, macula abdominali ad 

 extremum extensa, articulorum crurum juncturis albidis, tarsisque 

 albido et fusco annulatis. 



Long. foem. 2, maris \\ lin. 



In form this species closely resembles the common Leiobunus 

 rotundus ; but it is about one-fourth smaller, and has the legs 

 proportionably rather shorter and weaker. The 

 general colour is also very similar, the body of 

 the female being testaceous marked with brown. 

 A pale band extends up the front and middle of 

 the cephalothorax from the anterior margin to the 

 eye-eminence, enclosing two short dark lines 

 placed close together in the centre towards the 

 front edge. On each side of the pale band is an 

 irregular dark-brown patch, somewhat semicir- 

 cular in shape, the convexity being inwards, which 

 terminates posteriorly and externally in a sinuous curved mark.
