Willemoes-Suhm writes : “ In to-day’s haul I got the male of the curious Mysid 
taken on the 23rd, which presents very extraordinary characters. From the 
■ ist of Portugal down to the equator we got on three different occasions males 
and a female of a very large Amphipod, which I have described under the name of 
Thaumops j,eUucida [= Cyst i soma spinosuvi]. Most of the specimens were taken by 
tin- trawl when hauled up from deep water, and we did not know whether the 
animal lived only at great depths, or whether, like Phronima, it came to the surface, 
until one night a specimen was taken in the tow-net behind the ship. This shows 
ca arly, as might be expected from its transparency, that Cystisorna is a pelagic animal 
1 . ' _ during tin' day probably at a considerable depth, but coming occasionally at 
nipht to the very surface of the water. The eggs are very large and few in number ; I 
|, ,y, d> - nl d them as l>eing suspended from the first pair of ambulatory legs, but am 
ii"t now quite -ure whether that was only a casual incident, and that they are in reality 
contained simply within the breeding lamellae.”
