fifth, but shorter than the telson, which is narrow, triangular, grooved 
above, and armed with one pair of lateral spines about quarter way from 
the tip. 
The eye-stalks are about one half the length of the rostrum, and are 
furnished with a small tubercle on the inner side; the eyes are large, black, 
much broader than their stalks. Antennules longer than the carapace. 
Antenne as long as the body; scale narrow, margined within with long cilia ; 
a small spine on the outer side of peduncle at the base of the scale. The 
following pairs of appendages have the form characteristic of the genus. 
In the female there is a large process, covered with stiff hairs, and 
flattened on its inner side, developed from the base of the third pair of legs. 
Behind this process lies a pair of flattened, setiferous, sternal processes. 
Between the legs of the fourth pair there hangs in the median line a nearly 
vertical curtain-like partition, notched on the free lower margin, and flanked 
by two lower, blunt, setiferous tubercles. The sternum of the posterior 
thoracic segment has a slightly elevated median longitudinal ridge, and 
a low transverse ridge at the posterior boundary of the segment. The form 
of the petasma of the male is best understood by inspection of Figure 1% on 
Plate XLVI.

This species is apparently very similar to H. /wvs Bate, but the eye of 
the latter species is much smaller, the areolation of the carapace different in 
some regards, and, if Bate’s figure * can be relied on, the telson is much 
shorter. The two dorsal spines of the gastric region are situated much 
further forward in #7. /evis than in H. nereus. 
In Bate’s description of the genus Hualiporus in the “Challenger” Re- 
port (p. 284), the legs are said to be devoid of exopods, but on page 287
