Palinurus tumidus, sp. nov. 
Carapace beaked, much swollen, armed with very blunt spines, or rather 
spine-knobs, some directed forward, others, again, standing nearly vertical ; 
a double row of small, stout, blunt spines, standing nearly vertical, runs 
along the posterior edge of the carapace. Beak stout, round, and curved 
upwards. Supra-orbital spines stout, compressed, turned upwards. An- 
tenn spines stout, somewhat triangular in shape, and also turned upwards. 
Superior antenne less than the total length of the animal, peduncle armed 
on its upper and outer surface with stout spines. Inferior antenne smooth, 
longer than peduncle of superior. 
Anterior legs very stout, inferior margin of second joint armed with a 
row of five or six spines; third joint with a very stout spine at the anterior 
and also at the posterior extremity, the anterior twice the size of the 
posterior, also a stout triangular spine on the superior distal extremity ; 
fifth joint with a row of six spines on the superior internal angle, the largest 
and posterior one being directed backwards to meet the anterior spine of 
the third joint, a row of three small blunt spines on the inferior internal 
angle. Superior margin of the distal extremity of the third joint of the 
last four pairs of legs armed with a spine. 
Abdomen very coarsely granulated and punctated. Tail, especially the 
telson, armed with small spines ; telson rounded at the extremity. 
Anterior margin of each segment of the abdomen produced into a very 
prominent spine, backed by three or four teeth. 
Whole animal destitute of hair, with the exception of the pedipalps, 
and the inferior surface of the terminal joint of each pair of legs. 
Colour, reddish brown, tinged in many places with yellow. 
Length, 24 inches. 
Distinguished from P. hugelii by its much larger size, by the beak, 
supra-orbital and antenne spines being turned upwards, by the telson being 
less triangular, and rounded instead of Scarped.
