knob of pigment on either right or left side of the cephalo- 
thorax. It was found generally plentiful at 18 out of the 
23 Wyse stations, but not in any of the 6 most central of 
the Indian Ocean.

A few specimens were found in No. 20 Wyse collection, 
but not elsewhere.

One specimen only was taken, and that in No. 7 Wyse 
collection, from the Indian Ocean, which shows its range 
to be more southerly than was previously. known, the 
Mediterranean being its only previously recorded habitat.

The deep purplish black pigment covering to the dorsal 
side of the cephalothorax readily distinguishes this striking 
species. It appears to love the open ocean, occurring at 
eight consecutive Wyse stations, 7 to 14 in the Indian 
Ocean and Bay of Bengal, but not elsewhere. ‘The 
previous records are from the Mediterranean and Atlantic 
and Pacific Oceans.

The southerly range of distribution of this species 
appears to be very similar to that of C. ethiopica, but it 
has a wide northern range about our British coasts, and was 
recently reported from Port Erin, in the L.M.B.C. 
district.
