Willemoes-Suhm writes : “ Two specimens, 140 and 110 mm. in length, of an Astacid 
were brought up. They evidently belonged to the genus Nephrops, having all the characters 
of the Astaeids, especially the scale on the outer antennse and the ridge across the pereion, 
but in addition a long rostrum and very much prolonged anterior chelae. In this species, 
which was of a pure milk-white colour, the joints of the large chelae had a reddish-brown 
colour, like the borders of the abdominal rings ; in spirit the white colour gradually 
changed into a dirty reddish colour. The two hauls of the trawl brought up the same 
things : lobsters, shrimps, shells, and fishes. 
Ccelothamnus sedecimalis was observed among the Radiolaria in the deposit from 
this Station.
