14 AUSTRALIAN MA1AC0STBACA. 



Carapace nearly ovoid, convex, covered with long hairs set in 

 wart-like flattened tubercles. Rostral spines strong, triangular, 

 acute. Orbits deeply notched above, terminated posteriorly by 

 a small spine ; two other stronger spines after the notch, the 

 anterior the larger. Pour small spines on the sides, of which 

 the two first are obtuse, placed near to one another, the two last 

 acute, separated. Anterior legs in the male very large ; arm 

 with a series of strong spines above ; wrist with two ridges, the 

 inner divided into several lamellate or tuberculiform lobes, the 

 outer uninterrupted except at the base.

It is possible that the specimens referred to this species by 

 Miers and described above may, as the latter remarks, be distinct 

 from the P. barlicornis of Latr. No specimens of the New 

 Zealand species referred to P. barbieornis by Mr. Miers are 

 known with certainty to have been found in Australia. 



24. Paramithrax spatulifer. A.M. 



Paramiihrax spatulifer, Haswell, Proc. Linn. Soc. N.S.W., 

 Vol. vi. 



Carapace armed with a mesial longitudinal row of four spines; 

 bhe first two conical, acute, the first longer than the second, both 

 situated on the posterior portion of the gastric region ; the 

 third situated on the cardiac region, broad, antero-posteriorly 

 compressed, and bifid, the last, on the posterior border broad, 

 spatulate, heart-shaped ; two long sub-acute spines on each 

 branchial region, the anterior directed outwards, upwards, and 

 backwards ; a compressed bifid spine on the lateral border of the 

 branchial region. Rostrum formed of two rather slender widely 

 divergent cornua, each of which is bifurcate at the tip — the 

 inner branch being much the smaller and sometimes bifid — and 

 has some irregular teeth along each border. Upper orbital 

 margin produced upwards into a bifurcate process ; three post- 

 orbital spines — the last the broadest and obliquely truncate. 

 Basal joint of the antennae with a tubercle at the proximal end 

 of the outer border, a spine at its distal end, and another at the 

 antero-internal angle. External maxillipedes with scattered 

 granules and with a longitudinal raised granular line on the 

 ischium. Chelipedes in the male having the merus armed above
