102 DR. J. G. DE MAN ON THE PODOPHTHALMOUS 
portions of the postfrontal ridge. As in Z. Callianira, the upper 
surface of the cephalothorax presents on each side a transverse, 
somewhat oblique impression behind the lateral portions of the 
postfrontal ridge; these impressions are bordered posteriorly on 
each side by a transverse elevated line, which proceeds from 
the external margin of the epibranchial tooth towards the meso- 
gastric region. The orbital margins are smooth andentire. The 
external angles of the orbits are but little prominent, and the 
external margin of these angles appears smooth and entire. The 
epibranchial tooth is about as prominent as that of 7. Callia- 
mira. Behind this tooth the lateral margins of the cephalothorax 
are marked with numerous, oblique, piliferous elevated lines. 
The posterior margin of the cephalothorax, which is somewhat 
concave in 7’. Callianira, is perfectly straight in this species. 
The posterior half of the upper surface is somewhat punctate, 
and the gastric region is minutely rugose behind the six ridges 
or ridge-like elevations with which the cephalothorax is marked 
anteriorly. The pterygostomian regions and the inflected sides 
of the carapace are faintly rugose. 
As regards the outer foot-jaws, the characteristic longitudinal 
impressed line, which in many species is found on the outer 
surface of the ischium-joint, is completely wanting in this species. 
The male abdomen is triangular and less narrowed towards the 
terminal half than in Z. Callianira. The lateral margins of the 
penultimate joint are somewhat converging towards the anterior 
margin of this joint, the posterior margin of which is much 
broader than long. The terminal segment, which is rounded at 
the tip, and the lateral margins of which are slightly concave, is 
‘about as long as broad at its base. 
As the smaller chelipede is wanting, I can only describe the 
larger one. The arm and the wrist present the same structure 
as in 7. Callianira; the hand also much resembles that of the 
preceding species, but the lower finger is not at all deflexed. 
The fingers are distinctly shorter than the palm, which has the 
outer and inner surfaces quite smooth and convex; the under 
margin of the palm is rounded and smooth, the upper margin 
is minutely granular. The mobile finger is slightly arcuated, 
gaping, and minutely granular above; both fingers are grooveless, 
the index scarcely presenting any trace of a longitudinal groove 
near the tip. In their denticulation the fingers wholly agree
