CAMPYLASPIS TRIPLICATA Sp. nov. 
Adult male. Integument calcified brittle. Carapace with an upwardly 
curved depression on each side, bordered above and below by a fine ridge, 
and not reaching to mid-line of dorsum, below this and subparallel to 
the lower margin of carapace is a similar third ridge; above the lateral 
hollow the sides are tumid, then fall into a second faint elongate depres- 
sion not emphasized by ridges, and above this again is a further still fainter fur- 
row ; the dorsal margin is moderately arched, not quite evenly curved but slightiy 
rugose, and does not form a marked angle near ocular lobe; viewed from above it 
is ovoid in shape, narrowest in front; it is less than one-half the length of the 
animal, slightly depressed and nearly twice as long as deep. Antennal notch dis- 
tinct, widely open, and angle rounded and a little obtuse. Pseudorostral lobes 
subtruneate in front and meeting for a distance slightly greater than length of 
ocular lobe; respiratory tubes unusually long. Ocular lobe large, semicircular, 
wider than long, and with three large white corneal lenses. 

Fig. 37, Campylaspis triplicata, type male (X 37). 
First pedigerous somite largely concealed ; dorsal margin of first and second 
sloping obliquely backwards, not at all elevated; dorsum of third to fifth tumid 
but not markedly so; pleural parts of second to fifth only moderately expanded 
not much produced backwards. 
Pleon somites (like pedigerous) smooth; no sulcus on fifth somite; telsonic 
somite widest posteriorly where it is fully as wide as long, and with apex angularly 
rounded. 
Third maxilliped stout, with basis much shorter than rest of limb; merus 
rather wide (its greatest breadth a little more than half the length) longer than 
carpus, propodus and dactylus together, with two teeth towards distal end of outer 
margin; carpus much wider but a little shorter than propodus, with four curved 
teeth on outer edge and three less sharply defined on inner. 
First peraeopod with basis shorter than rest of limb; remaining joints with 
margins irregular but without teeth; merus, carpus and propodus subequal in 
length (merus longer than carpus, which is longer than propodus) ; dactylus rela- 
tively long, five-sixths as long as propodus. 
Second peraeopod about equal in length to first, with basis almost as long 
as remaining joints together ; dactylus much longer than merus or carpus, which
