A male, in which tiiere is a small distinct tooth on the 

 base, posteriorly, of each first antero-lateral tooth, and a slight 

 pubescence on the branchial regions. G. rostratum differs 

 only in being less orbicular, in having the two median teeth 

 of the front more advanced, and in the possession of only two 

 spines on the hand, and I do not think it is specifically 

 distinct.
