Vanhoft'en in the paper cited has discussed C. perforate, and 

 Stimpsoni, retaining them in the genus Cydoidura. In the same year 



1 instituted the genus Parisodadus for these two species. As I have 

 not been able to consult Vanhoffeu's paper, the discussion as to the 

 correct genus for these same species must be postponed. 



ZUZARA FURCIFER n. sp. 

 (Plate XV. Figs. 26, 27.) 



Male. Body non-setose, minutely granulate, chiefly on the posterior 

 margins of the peraeon segments. Head with a small median 

 tubercle on the anterior margin, flanked on either side by 3 other 

 inconspicuous tubercles. Peraeou smooth, 7th segment with a long 

 median process reaching back to f length of the telson, apically bifid. 

 Two tubercles on the posterior margin of the lateral portions of 7th 

 segment. Side-plates nearly vertical, 2-5 not greatly narrowed below, 

 postero-iuferior angles subacute, a low keel at the junctions of segments 

 5-7 with their side-plates. 



Pleon segments 2-4 distinct though closely fused. Telson convex, 



2 pairs of small tubercles near the base, 2 more pairs a little beyond 

 the middle and more widely separated, apex ending in a projection 

 with a rounded notch on either side. The points bounding these 

 notches as well as the median projection apically blunt. The latter is 

 about -5- length of the process on the 7th peraeon segment, and bears 

 a small tubercle on its upper surface at the base and is raised some 

 little way above the lateral points, so that there is a distinct ventral 

 groove. 



Antenna 1 reaching to end of 1st peraeon segment, 1st joint twice 

 as long as broad, 2nd | length of 1st, flagellum equal to peduncle, 

 10-joiuted. 



Antenna 2 reaching to end of 3rd peraeon segment, 5th joint a 

 trifle longer than 4th, flagellum equal to peduncle, 11-jointed.
