four pairs havc strongiy developed carinfe on the femora (Pl. 

 Y fig. 59). The femur of the seveuth pair is longer than 

 broad (24 : 17) (Pl. V fig. 60). 



The pleon is broad, much broader at the base than long 

 (5 : 3). The first segment is almost totally hidden, the pleon 

 being a little more immersed than in Cymotlwa elecfcnis. The 

 last is broadest and longest, the three preceding being equal 

 in length. The second pair of ^aleopoda carry very long styli- 

 form processes (Pl. V fig. 61). 



The urus is as long as the pleon, and ouly a little broader 

 than the last pleonal segment (12 : 11); it is smooth on its 

 upper side, broadly ronnded at its lateral and hinder margins, 

 exactly twice as broad as long. The pleon and urus togcther 

 are equal in length to half of the pereion without the head. 



The uropoda do not reach to the hinder margin of the 

 urus. The peduncle is shorter than the inner ramus. The 

 inner ramus is longer than the outer. 



Coloiir. Yellowish-white with smaller and larger brown- 

 red spöts on the anterior part of each segment; the 

 posterior part is almost white. 



Lengtli. The female virgo 17 m. m. 

 The males 12, 15, 16 m. m. 



Hah. The south coast of Hayti, (Z. M. C. B.). 



I got four specimens, a female virgo and three males, 



in the harbour of Jacmal, Hayti, in the month of April, 



1883.
