the length of the branches from which they spring, are plain on the inner and serrate 

 on the outer margin ; the inner branches have no terminal spine ; both branches are 

 provided with several long plumose setse (fig. 29). 



Sabitat. Lat. 1° 55' 5" N., long. 5° 55' 5" E., in a gathering from 360 fathoms, collected 

 January 22nd. One specimen only was obtained. 



A form that may be an immature stage of the foregoing was obtained in a surface 

 tow-net gathering from Loanda Harbour, collected February 15th, and is represented by 

 fig. 58. The anterior antennre are 2-jointed ; the posterior foot-jaws are large and well- 

 developed ; the siphon is elongate, with a flattened sucker-like disk at the extremity 

 (fig. 30) 



This form is closely analogous to the immature stage of Caligus, formerly described 

 as a distinct genus under the name of Chalimus.

 two species having been obtained in the whole of the ' Buccaneer ' collections. They
