THE VOYAGE OF H.M.S. CHALLENGER. 
Station 221. specimens of Coryph^na were seen, as well as some fishes jumping about the surface of 
the water. The screw was taken up and found to be covered by a small Tuhularia, 
along with Lcpas, Balanus, Caprella, and a small crab. 
Willemoes-Suhm writes : “ Lucifer was plentiful and I found its larva in abundance, 
and also some Zoem which, I think, belonged to it. They were much smaller than the 
corresponding stages of Sergestes^ but I afterwards found that the full-grown Zoea of 
Lucifer was about the same length as the spiny Elaphocaris (Zoea of Sergestes), and 
dificred only in the absence of spines.” 
Moseley vTites : “On the 15th the tow--net was filled with a Corycseus, the same 
species as that figured by Suhm from the Atlantic, with the prominences of the body for 
the reception of the nervous parts of the enormously-enlarged eyes.”
