326 JOHN HEWITT. 



The granules on the mesial portion of the last abdominal 

 sternite o£ the male more numerous and not quite so large as 

 in the male of pugnax proper (about ten or twelve rows can 

 be roughly counted between the anterior and posterior 

 margins) ; in the female this area is covered with low granules 

 and irregularly shaped ridges, which occur throughout the 

 whole length of the segment, more or less obscuring the keels 

 (these are quite obsolete in the Estcourt specimen, but present, 

 though indistinct, in the Mooi River specimen). 



Infero-median keels of first caudal segment in the male com- 

 posed of about eight to ten coarse granules, and the space 

 between them also includes about ten coarse granules, but is 

 not obliterated thereby nor are the crests rendered indistinct 

 to any great extent ; in the female these keels are pitted and 

 more or less coarsely granular (in the Mooi River specimen 

 the keels are not definitely broken up into coarse granules), 

 with a few granules between the keels. 



The abdominal tergites in the female are all granular 

 throughout, coarsely so in the posterior portions of each tergite. 



Pectinal teeth : Thirteen to fourteen male, eleven to twelve 

 female (thirteen to foux-teen in the Mooi River specimen). 



Measurements. — Total length, male 78 mm., female 89 

 mm.; length of hand, male 17"3 mm., female 18'8 mm.; of 

 movable finger, male 11"75 mm., female 12"3 mm.; of hand 

 back, male 6 mm., female 7 mm.; breadth of hand, male 8 mm., 

 female lO'b mm.; length of cai'apace, male 11*7 mm., female 

 18 mm.; distance of median eyes from posterior margin, male 

 3"75mm., female 3'7 mm.; width of first caudal segment, male 

 5"75 mm.; of fifth caudal segment, male 4*25 ram.; length of 

 same measured along the side 10 mm.; breadth of vesicle, 

 male 4'25 mm.; length of same 10 mm. 



In respect to the shape of the hand and the granulation of 

 the last abdominal sternite and of the infero-median keels of 

 the first caudal segment in the male, this form is intermediate 

 between typical pugnax and the iorm described by me from 

 Keilands under the name of 0. latimanus Koch var.
