This new species differs from G. tenuitesta in having an acute 

 apex, a deeper suture, in the whorls being gibbous at the upper 

 suture, in the last whorl being more sloping behind the columella, 

 and lastlv in being distinctly costulate-striate. Eiom G. leptosjnra 

 it may be separated by the straight sides of the spire, the acute 

 apex, and the narrower base. One specimen possesses 9^ whorls, 

 and measures 18-25 x<5 mm. Two of the earlier whorls appear 

 to have been fractured at an early stage, so that the shell has the 

 spire slightly tilted.
