BEACHTUEA FEOlVr TOREES STRAITS. 39 



tlie number being made up by the intercalation of a small spine just in front of the lar'>-e 

 one on the cardiac region. All the spines of the carapace are distinctly knobl)ed at the 

 tip. The supra-ocular hood is deeply divided into two teeth, of which the anterior is acute 

 and turned upwards and forwards while the posterior is truncate. The nieriis of the 

 ambulatory legs bears two spiniform tubercles distally. The rostral spines are strongly 

 divergent and hardly more than one-third of the length of the carapace. 

 Locality. " Torres Straits."

One female and three male specimens, belonging to the typical form of this species as 

 described by A. ;Milne-Edwards, having only one accessory spiuule on each of the rostral 

 horns. The largest male, 2G mm. in length, is still immature, the chelipeds beiu"- no 

 longer than the succeeding legs. In the other two males, 17 and 12 mm. lon*^^ respectively 

 the carapace is relatively narrower, and in the still smaller female the distance between 

 the extra-orbital spines is hardly less than the greatest width of the carapace. In the 

 small specimens the surface of the carapace between the large tubercles is quite smooth.

Three male specimens, agreeing with Miers's types of this briefly described species, and 

 showing the characters assigned by him to the male sex, the gastric region being but 

 little elevated and the rostral spines not perceptibly deflexed. 



The only point indicated by INir. Miers as distinguishing this species from the P. tenuipes 

 of A. Milne-Edwards (Ann. Soc. Ent. France, (4) v. p. 139, pi. v. figs. 2, 2 a, 1865) is the 

 character of the sternal surface, which in the last-named sj)ecies is stated to be 

 " remarquable par I'existence a la ligne de jonction de chaque anneau de cretes saillantes 

 et legerement granuleuses." In addition to this, how^ever, certain small differences in
