"pattes courtes et paraissant obtuses au bout, les dactylopodites étant rudimentaires". This may be 

 perfectly applied to my new species, but unfortunately the diagnosis oi Pinnixa brevipes^ ofwhich 

 no figure exists, is very short, and the carapace presents a curved groove in his posterior third. 



The species was found, cf and 9 together, in the tube of a Terebellid [Loiiiiia).

In the course of the present work I have frequently feit the need of a faunistic list of 

 Indo-Pacific Pinnotheridae. For the help of any one, who chances to study collections of this 

 family and who wishes to arrive at least to a provisional survey of the genera and species to 

 be expected from some subregions of the Indo-Pacific, I append the following list.
