AUSTRALIAN MALACOSTEACA. 297 



several spines, with a deep, rounded terminal notch, immediately 

 above which is a prominent spine. Eyes large and prominent ; 

 antenna? subequal, nearly one- third of the length of the body. 

 Mobile ramus of uropoda bifurcate, the outer branch short, tooth- 

 like, the inner long, slender, spiniform ; immobile ramus broad 

 proximally, but slender and spiniform distally, its outer border 

 armed with two acute teeth, its inner with one. Length f in. 



Port Stephens five fathoms. 



513. Ciliccea spinulosa. A.M. 



Cilicoea spinulosa, Haswell, 1. c, p. 4, pi. in., fig. 3. 



Head large and dilated, covered with rounded and pointed 

 tubercles. First segment of the thorax much broader than the 

 rest, armed with a number of short blunt spinules, and with a 

 prominent bifid tubercle on either side ; its lateral process 

 obscurely bilobed. Following segments each armed with a row 

 of short spinules, which are more numerous and smaller on the last 

 three segments ; epimeral processes prominent, subacute, except 

 that of the fifth, which is emarginate. First segment of the 

 abdomen ornamented at the base with a double transverse row of 

 tubercles ; posterior process finely granular, sub-cylindrical, 

 slightly enlarged or bifid at the apex, extending far beyond the 

 extremity of the abdomen, but not so far as the extremity of the 

 uropoda. Terminal segment having its lateral dilatation armed 

 with two short thick spinules ; terminal notch deep. Antenna) 

 sub-equal, about one-third of the length of the body. Uropoda 

 with the movable ramus slender, bifurcate, the outer branch 

 short, tooth-like, the inner longer, slightly curved outwards, sub- 

 acute ; immobile ramus a little longer than the mobile ramus, 

 broad at base, but tapering to the apex, which, is curved outwards 

 and acute. Length | in. 



Port Stephens and Port Jackson. 



A near ally of the preceding species. Specimens from the 

 same localities which are probably the females of this species 

 (Plate iii., fig. 2) or of C. hystrix arc distinguished by having all 

 the spines of the body replaced by tubercles, by wanting the 

 posterior process of the first abdominal segment, and by having 

 the rami of the uropoda smaller.
