AMPHARETIDAE 183 



and continued over its entire length. This condition is exactly similar to that described 

 by Benham (1921, p. 98) for the gill of his P. dibranchiata. Moreover, there are three 

 tubular ducts running down from the bases of the gills to the notopods. That from the 

 outermost gill runs to the ist chaetiger, that from the second gill to the 2nd chaetiger, 

 and that from the hindmost of the inner pair on each side to the 3rd chaetiger. The 

 anterior member of the inner pair on each side has no duct visible externally. The 

 condition is as if the ceratophores of the gills were fused to the back as they ran 

 outwards towards the notopods. 



In Benham's account of P. dibranchiata he describes analogous ducts as channels 

 open near the gill base, and roofed over on their way to the notopods. In this they 

 differ from those of the present species, in which the "channels" are closed tubes 

 throughout. These ducts are the "areolae" of Grube. 



This species is clearly distinct from Benham's P. dibranchiata, which has a single 

 pair of gills, each with four membranes. Benham is mistaken in saying that Grube 

 ascribes two pairs of gills to P. crocea, for Grube writes: "Branchiae utrinque 4 

 dorsuales." 



The dorsal bristles (Fig. 75, e) correspond exactly to those described by Benham for 

 P. dibranchiata. They all have the curious third flange which Benham describes and 

 figures. The hooks are well figured by Mcintosh.
