markably pediform, the fossorial legs are stout and short, with basis not enlarged 
in exopod-bearing pairs of the male, and the uropods are relatively massive. The 
latter resemble those of Campylaspis platywropus Calman (1911, p. 364, pl. xxiv, 
fig, 25-29) which by this character stands apart in its genus. The second male 
antennae resemble those of Lamprops fuscata Sars (1899, p. 20, pl. xi). For 
the present, however, it seems best to consider Picrocwma as an aberrant genus of 
the Nannastacidae. 
PicROcUMA POECILOTA Hale. 
Picrocuma poecilota Hale, 1936, p. 415, fig. 7-8 and 1943, p. 338, fig. 3-6. 
Adult male. (Table Bay, Tasmania). Integument slightly roughened, some- 
what. polished. 
Carapace small in relation to whole animal, barely longer than pedigerous 
somites together, two-sevenths of total length, distinctly compressed and with 
depth equal to nearly three-fourths its length; seen from the side the dorsal con-

Fig. 22. Picrocwma poecilota. Adult male, lateral view and (ceph.) cephalothorax from 
above (X 72). Adult female; c. pace, anterior portion of carapace showing outline of mandible 
(X 72); ceph., dorsal view of carapace and first three pedigerous somites (< 40). 
tour is slightly and smoothly arched, with a not very pronounced angle at base 
of pseudorostrum, which is not at all upwardly directed. Antero-lateral margin 
very shallowly concave and oblique; no indication of antero-lateral angle. Pseu- 
dorostral lobes roundly subtruncate in front, oblique as seen from the side, meet- 
ing in front of ocular lobe for a distance equal to one-tenth of length of carapace. 
Ocular lobe twice as wide as long, sooty and with a pair of darker areas apparently 
representing the eyes (fig. 22, ceph.). 
All five pedigerous somites fully exposed; second much the longest, twice as 
long as third or fourth; fifth longer than fourth and first shortest of all; pleural 
portions scarcely or not at all expanded. 
Pleon nearly twice as long as pedigerous somites together; somites one to 
four suecessively increasing in length; fifth abruptly longer, half as long again 
as fourth, and half as long again as wide ; telsonic somite as wide as long, posteriorly 
rounded, little produced, and somewhat dilated, but not strikingly so.
