The antennules are short; the peduncle is about one-fourth 
the length of the rostrum, the first joint is excavate above, 
its stylocerite spine being very strong and reaching well in 
advance of the end of the joint, the second and third joints 
are subequal in length, rather swollen above, together they 
are shorter than the ophthalmopod, the upper flagellum 
reaches rather more than half the length of the antennal 
scale, the lower one is a little longer than the scale. 
The antennal scale reaches about two-thirds the length of 
the rostrum, it is broader than is usual in the other species, 
and is strengthened by two longitudinal ridges above, the 
distal spine is terminal, the external spine on the second 
joint of the peduncle is strong, and above it at the base of 
the scale there is an acute projection. The remaining joints 
of the peduncle are nearly one-fourth the length of the 
scale. The flagellum is slender and long. 
The third maxillipeds reach nearly to the end of the an- 
tennal peduncle, of the three joints, the distal portion of the 
first, the second, and third are slightly excavated on their 
upper expanded 'surfaces, the third joint is acuminate dis- 
tally, with a strong terminal spine, four others on the outer 
side and two or three on the inner: between the spines are 
very short teeth, the joint also along with the second is 
strongly setose on the inner side. 
The first pereiopods resemble those of 4. robusta, as also 
do the second, o a peculiar bend at di junction of the 
basis joint with t the емши: and there is only one spine on 
the ischium. 
The third and fourth pairs are vobust and long, the meri 
bear two spines below near the distal end, and are fringed 
with plumose sete, the carpi are short and expand well dis- 
tally, the propodi taper a little and are well spined on their 
posterior margins, the dactyli are short, little curved, and 
have two strong claws. 
The fifth pair are rather less robust, the merus haviug 
only one spine. The pleopods are well developed, the rami 
subequal in length. 
The uropod) are rather narrow, as long as the telson. 
The ova are small and numerous. 
Length, excluding rostrum and telson, 28 mm. 
Length of carapace, 13 mm. 
Dredged by Dr. Verco, S.A. coast, about 20 fathoms. 
Types, two, in Adelaide Museum. 
Another species obtained belongs to the genus Alope, of 
the family Hippolytidw, and is related to a species, Alope 
palpalis, White, which is figured in the zoology of the Erebus 
and Terror, Crust., pl. iv., fig. 1, and for a-long time was im- 
perfectly known until recently redescribed by Mr. G. M.
