Remarks. There is a certain amount of variation in the relative length of the pedal 

 lips, but otherwise these specimens are uniform. 



I am doubtful of the necessity of keeping G. capitata and G. lapidum separate. They 

 are usually distinguished on the following characters : G. capitata has eight prostomial 

 rings, the support of the jaws is hardly, if at all, notched in the middle and the bristles 

 of the lower bundle are all of the same size. G. lapidum has eleven prostomial rings, 

 the support of the jaws is deeply notched in the middle, the ventral cirrus is more 

 pointed and downwardly directed than in G. capitata, and the upper and lower bristles 

 of the ventral ramus are stouter than the rest. 



Regarding the number of prostomial rings, in the majority of these specimens this 

 cannot be counted with sufficient accuracy to be of any differential value : the supports 

 of the jaws are in many examples deeply notched and with one arm elongated : as a 

 specific differential this character seems to be valueless. Moreover, the extent to which
