HALE—AUSTRALIAN CUMACEA 205 
Pleon somites one to five with long and sbort spines on back and with upper 
edge of antennal furrow spinose; a few shorter spines infero-laterally ; fifth so- 
mite without trace of transverse suleus; telsonic somite rather narrow, distally 
rounded and moderately produced. 
Second peduncular joint of first antenna shorter than first, longer {han 
third and about us long as the flagellum, the two segments of which are sub- 
equal in length, 
Last joint of peduncle of second antenna half as long again as penultimate, 
First maxilliped with terminal joint more robust than usual in the genus, 
more than one-fourth as long as penultimate segment, not much more than twice 
as long as wide, slightly constricted near apex, which bears two minute setae, and 
with a row of tiny setae on outer distal edge; penultimate joint with some unequal 
short getae (see fig. 42) and two stout plumose setae; twenty-two gill lobes, 

Pig. 41, Canpylaapis echinata, lateral yiew and dorsal view of pedigerous somites (x 20). 
Distal joint of second maxilliped with # short seta and two stout unequal 
spines, the longer not reaching to the level of the tip of the outer spines of the 
penultimate joint. 
Third maxilliped with basis stout, longer than rest of limb, with serrations 
and distal tooth on inner edge; ischium with two inner blunt teeth; merus nar- 
row, with small teeth in both margins and a large outstanding subdistal onter 
tooth, almost as long as the joint is wide; not including the teeth the meris is 
three times as long as wide and is not nearly as long as carpus and propodus to- 
wether; carpus with denticles on inner edge and three separated outer teeth the 
middle one of which is long; propodus elongate, nearly half as long again as carpus, 
und unarmed, 
First peracopod with basis stout, longer than rest of limb, which is slender ; 
merus serrate on both margins and with a larger outer tooth near distal end; car- 
pus serrate on both edges, barely more than three-fourths length of merus and ¢lis- 
tinetly longer than the propodus, which is less than twice as long as dactylus. 
Second pera¢opod not longer than first, its stout basis longer than ischium 
(o propodns together; dactylus longer than carpus, almost as long as carpus and 
propodus together and with longest terminal seta two-thirds its own length,
