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

 perfectly applied to my new species, but unfortunately the diagnosis oi Pinnixa drevipes, of which 

 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 [Loimia). 



Dimensions in mm. : 



Fronto-orbital distance 



Distance between bases of antennae . 



Breadth of carapace

In the course of the present work I have frequently felt 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.
