Remarks. — This specimen was obtained when the present paper was 

 almost completed. I have only one male and two small female specimens, 

 and have not had time to make a full examination of them. It appears 

 to be a true Elasmopus, coming fairly close to the three species described 

 above, but readily distinguished from them by the absence of carination 

 on the fourth pleon segment and by the very peculiar left second gnathopod 

 in the male.
