In one of tbe specimens with petasmata, those organs are 

 in precise agreement with the same parts as figured for an 

 example obtained by Dr. Bruce's " Scotia" Expedition. The 

 present specimens have more slender eye-stalks with the 

 lateral process more produced, and the little tooth at the end 

 of the scale of the second antennae is rather longer, but the 

 details in general present no differences. The length of a 

 female specimen was 31 mm., and the male with petasmata 

 well developed was approximately the same. It is no doubt 

 nearly allied to G. calmani, Kemp, which appears to be a 

 considerably larger species, and distinguished by a prominent 

 ventral spine on the first pleon segment in both sexes, not 

 found in either sex of the present species.
