(Station 2), with a temperature at the latter depth of 
5°2C. The general character of the fauna was that 
which we have hitherto been in the habit of regard- 
ing as Northern. Several interesting things were

Fic. 8.—Gonoplax rhonboides, Fasricius. Young. Twice the natural size, (No. 3.)

Geryon tridens, KRoyER (Fig. 9), a rare Scandinavian 
form, and the only known North European _bra-
