taken several specimens measuring eight inches in dia- 
meter. Almost every specimen forms a habitat for a great 
number of examples of the Caprellid Podalirius typicus,

out behind, the sharp pointed terminal joints giving a very 
firm hold.

In this species we have the fourth addition to our list 
made during the ‘‘ Hyena”’ expedition of 1888. It was 
taken, with the three previously mentioned, from a depth 
of 20 fathoms off the south-eastern corner of the Isle of 
Man, and with them and the subjoined Lwdia savignu 
serves to show how rich and varied is the Echinoderm 
fauna of that district.

of about ten fathoms in the Menai Straits, close to the

Southport.
