Four males and three females of this little spider were found 
on October 31st and November 5th, at Oakmere. The species is 
quite new to Britain; and, as Mr. CAMBRIDGE believes it to be a 
new species, I have now described it as such.

ORDER II.—PHALANGIDEA. 
Oligolophus spinosus (Bosc.) A female taken at Brigstock, 
Northamptonshire, and sent to me by Mr. H. W. FREsTOon, of 
Poynton, Cheshire. 
Oligolophus Meadii (Camb.). About a dozen examples from 
Oakmere on October 31st and November 5th. Mr. CAMBRIDGE 
believes that some of them, at all events, are adult. This inter- 
esting Arachnid has only previously occurred in Dorset and 
Sussex. It is unknown on the Continent; but it has been 
suggested that possibly the British specimens are not mature. 
Anelasmocephalus Cambridgit (Westw.). Four or five speci- 
mens were obtained at Guestling and Fairlight, near Hastings, 
and were sent to me by Mr. BENNETT. 
Trogulus tricarinatus (Linn.) Mr. WALLIS Kew, of Bromley, 
kindly sent me two examples of this species. One is adult, and 
is the first adult Trogulus obtained in Britain. The other is very 
young. The former was obtained on “the Warren,” at Folkes- 
tone, on May 5th, 1905, and the latter, four days later, at 
Cudham, Kent, A very young example was taken at Bloxworth, 
Dorset, in April some years ago. I, myself, found an immature 
Trogulus at Deepdale, near Buxton, in 1899. It was seen and 
recognised by the late F. O. P. Cambridge. Probably it was 
referable to this species, but the specimen is now lost. 
ORDER III.—CHERNETIDEA. 
Chthonius Rayit (L,. Koch). Several examples from Hastings. 
Mr. BENNETT. 
Chthonius tetrachelatus |Preyss). A single specimen from 
Mr. BAGNALL; it was obtained at Ormidale, Kyles of Bute, 
under a stone on the shore. 
Obisium maritimum (Leach). This interesting animal is not 
rare at Port Erin. Its habits are somewhat abnormal, so I here 
make a short note on them. It inhabits the crevices of the rocks 
there. These are of the Silurian series; they are slaty and 
cleave easily; the clefts being chiefly in the vertical direction. 
They are well below high-water mark, but are uncovered at each 
low tide. They are, of course, covered with algze and barnacles, 
limpets, &c. When a chisel is used, flat pieces are easily separ- 
ated. The under surface of these pieces of rock, and the beds from 
which they are removed are seen to be covered with a fine damp
