Observations. This extremely characteristic specimen ranges as 
far south as 60° N. B!) and — for aught we know at present — 
as far north as 79°. It was collected at very different places, 
yet seems never to be very abundant. With the ©. angusta 
G. O. Sars they are the single representatives of the Genus Üolos- 
sendeis in higher Northern latitudes, whereas numerous forms 
of this same genus inhabit southern latitudes as I was able to 
ascertain with the rich material of the Challenger-expedition. The 
present species with its highly concentrated body is easily to be 
distinguished from any other species of the same genus. 
1) Writing these lines Mr. Murray of Edinburgh sends me the Pyenogonids 
he recently collected between the North of Scotland and the Faröe at a La- 
titude of 60° 3 N. Between these there are four Colossendeis proboseidea : they 
are all females.
