The Discovery of Brachychasteuma melanops. 



A few months after Brachychceteuma bradece had been 

 made known I happened to be in London, and between 

 appointments with Admiralty officials 1 spent a short week- 

 end with a friend in the Honorable Artillery Company, then 

 encamped at Swanage. Thus it happened that on the evening 

 of my arrival on April 6th, 1918, and when it was almost 

 dusk, I stumbled upon another species of the genus, which 

 occurred in numbers below Belle Vue, and, proving to be 

 new, has been described by my friends under the name 

 Brachychceteuma melanops f. 



The cliffs at Belle Vue are very beautiful, standing out in 

 somewhat marked contrast to those on either side. High 

 up are plantations of evergreens, cedars, pines, laurestinas, 

 and holly-oaks, and from here one can see the bay flanked to 

 the left by a green-clothed prominence screening Peveril 

 Point, and to the right by the undercliff stretching away to 

 Durlston Head. The undercliff s are intersected by paths, 

 the main one leading to Durlston Head, but here broken 

 away and there perhaps blocked by a fall of rock from 

 above; the undergrowth is chiefly of bracken and bramble, 

 but towards the u Head" and below the plantations are little 

 groves — conifers, poplars, and privet predominating, — with 

 tracks leading perhaps to a little knoll or winding to the 

 shore below. 



I first discovered B. melanops in some plenty by scraping 

 the surface covering of fallen leaves and needles in the lower 

 plantations and groves where somewhat damp; later I found 

 it under stones, but only in this sparsely wooded area, and 

 not on the undercliffs. It was very plentiful — perhaps the 

 most plentiful myriapod in early April, — but was found in 

 less numbers six weeks later. 



In October 1918 I found a few examples of a Brachy- 

 chceteuma in the neighbourhood of Torquay and Babbacombe 

 which proved to be the Swanage species, B. melanops, and 

 on December 31st, 1918, and New Year's Day, 1919, it
