MICROMIMONECTIDAE 



251 



Remarks. This specimen does not appear to differ from irene as far as one can judge 

 from the figures given by Woltereck for the ovigerous $. It has the body filled with a 

 very fine granular mass which may possibly be developing ova, but there are no brood 

 lamellae. 



The mandibular palp was evidently 3-jointed, but the terminal joint on both mandibles 

 is now missing. Maxillae 1 and 2 are as figured ; the latter has two very strong spines on 

 the outer lobe and three on the inner lobe. The maxilliped resembles that of a Vibilia, 

 but has the inner plates separate. 



Distribution. Indian Ocean (off Sumatra).

apex acute, reaching to half length of peduncle of uropod 3. Posterior portion of 

 alimentary canal opaque. 



Antenna 1, terminal joint ensiform, smooth. Antenna 2 about as long as antenna 1, 

 5th (4th free) joint elongate, ensiform, upper margin finely setose. Mandibular palp 

 with a few long setae at apex of 2nd joint, 3rd joint shorter than 2nd, slender, curved. 



Gnathopod 1, 5th joint triangular, distal width equal to length, 6th ovate, dactyl half 

 length of 6th. Gnathopod 2, 5th joint cylindrical, 6th narrow-ovate. 



Peraeopods 1-5 similar, elongate, peraeopod 5 shorter than peraeopod 4, 5th joint 

 narrow-ovate, scarcely swollen, 6th elongate, slender, longer than 5th, dactyl very 

 slender, about two-fifths length of 6th joint.
