pedigerous somites almost perpendicular as seen from the side and not even slightly 
elevated ; the appendages, ete., are as in the type. 
Apart from platyuropus Calman (1911, p. 364, pl. xxxiv, fie, 2! 29), this 
is the only known unicarinate member of the genus. 
CAMPYLAEPIS RUPTA sp. nov. 
Adult male, Tntegiument not strongly calcified, not brittle but tough and not 
easily torn. 
Cavapave with strong sculpture, consisting of shallow depressions with tuimid 
edges; the largest excavation is lateral, above it are two dorso-lateral depressions 
in posterior half ; anterior to it is an excavation behind the antennal area and imme- 
diately above it is a small hollow (fig. 31), the mid-line is ridged and irregular. so

that seen from the side the dorsal contour is markedly uneven, slightly arched and 
somewhat concave at base of ocvar lobe; viewed from above it is widest in pos- 
terior third but is considerably broadened anteriorly owing to a large tumidity at 
the upper anterior part of the largest lateral depression; it is two-fifths of the 
total length of the animal, depressed and twice as Jong as deep. Antennal noteh 
widely open and angle obtuse. Ocular lobe rounded, wider than long with three 
distinet corneal lenses arranged in a triangle and a further conjoined pair, less 
distinet, on each side. 
First to third pedigerous somites each with a transverse carina, medianly 
sharply elevated and with a pair of small tubercles; fourth and fifth somites each 
with a pair of longitudinal dorsal earinae. 
Pleon narrow ; first four somites each with a pair of dorsal carinae as in 
posterior pedigerous somites. Fifth somite slightly constricted at two-thirds of 
Jength as seen from above but with no transverse suleus; from the side no con- 
strietion is apparent but there is a slight ventral indentation at this point; this 
somite has a median longitudinal carina, most distinct on posterior half: telsonic 
somite produced more than usual in genus, with apex rather narrowly rounded, 
and with median carina; it is much longer than wide. 
First joint of peduncle of first antenna as long as second and third segments 
together; flagellum two-jointed, as long as third peduneular joint and shorter 
than second.
