Remarks. All these specimens agree with Henderson's figure of the type- 

 specimen (1893) in being without setse on the inner margin of the inner 

 uropod (except for three or four at the extreme proximal piart). 



In the arrangement and number of tubercles on the telson, they agree 

 generally with that shown in Kemp's figure 109, that is, the tubercles are 

 large and few, but they show evidence that the tubercles increase in number 

 with age and, likewise, become more obtuse, as the following description of 

 the tuberculation of each specimen will show. 



cJ , 14 mm. 



Two median tubercles, one behind the other, on the median carina, one on 

 each submedian carina, one on the carinse of the submedian teeth, and one 

 on the carinse of the intermediate teeth. All the tubercles very acutely 

 pointed and spiniform. Carinse of the sixth abdominal segment likewise 

 ending in sharply pointed spines. 

 $ , 14 mm. 



As above, except that there are two tubercles on the carinas of the inter- 

 mediate teeth. 



J", 19 mm. 



Three spinous tubercles, forming a well-marked trident at the distal end 

 of the median carina, two tubercles On each submedian carina, two at the 

 base of the submedian teeth, and three on the carinse of the intermediate 

 teeth. All the tubercles acutely spinous, as are also the carinse of the sixth 

 abdominal segment. 



? , 22 mm. 

 Three spinous tubercles, forming a trident, at the distal end of the median 

 carina ; anterior to them a smaller median spinous tubei - cle flanked by a very 

 small obtuse tubercle on each side ; two tubercles on each submedian carina, 

 three at the base of the submedian teeth, and three on the carinse of the inter- 

 mediate teeth. All the tubercles and the carinse on the sixth abdominal 

 segment, acute but not so sharply pointed as in the smaller specimens. 

 $ , 27 mm. 

 Almost exactly the tuberculation of the last specimen but all the tubercles 

 obtusely rounded. This specimen agrees very closely with Kemp's figure 

 109. 



? , 30 mm. 

 Like the last, but only two tubercles at the base of each submedian tooth. 

 All the tubercles obtuse. 



These six specimens, therefore, form a compact group agreeing in the 

 unarmed inner margin of the inner uropods and having a tuberculation of 

 the telson following a general plan though varying with age. I regard 

 them as referable to the typical form of the species, though Henderson 

 (1893) figures the spinules on the telson of the type as distinctly smaller and
