gastric spinule. 3. Immediately posterior to the cardiac is a small 

 median spine resembling it in shape but only about one-quarter its 

 length. 4. The posterior margin of the carapace is armed with a row 

 of spiniform tubercles as also are both carinae of the 2nd, 3rd and 

 4th and the anterior margin of the 5th abdominal segments ; the terga 

 of the 5th and 6th abdominal segments are irregularly covered with 

 small sharp granules while their pleura are almost smooth. 5. The 

 upper surface of the meri and carpi of the 2nd-4th thoracic legs are 

 covered with tubercles similar to those on the carapace. 6. The 

 posterior margin of the dactyli of the 2nd-4th thoracic legs are 10-12 

 dentate. 7. The 1st, 2nd and 3rd antennal joints terminate in short 

 sharp spinules. 



From G. hella it differs : 1. In the distribution of tubercles on 

 the abdominal segments and on the upper surfaces of the meri and 

 carpi of the 2nd-4th thoracic appendages. 2. In the presence of 

 spinules on the antennal joints. 3. In the presence of two median 

 gastric and two median cardiac spines. 4. In the number of denta- 

 tions in the posterior margin of the dactyli of the 2nd-4th thoracic 

 legs. 5. In the cutting edges of the fingers of the chelipeds being 

 quite straight. 



From G. rostrata it differs : 1. In the presence of two gastric 

 and two cardiac median spines. 2. In the two spines on the lateral 

 margins of the carapace being subequal. 3. In the spinature of the 

 ambulatory legs. 



Colour in life milky orange. 



A female specimen was obtained from each of the three Stations 

 184, 192 and 193 at depths of 947, 912-931 and 931 fms. respectively.
