Stimpsou considers Porcellana magnified, Gibbes, 1850, to be 

 a synonym of this species. The colouring in our preserved 

 specimen is very attractive, the chelipeds being a bright red, 

 the terminal joints of the ambulatory limbs barred red and 

 white, their broad fourth joints and the carapace of lighter 

 hue, reddish varied with white. This scheme of colouring is 

 suggestive of Petrolisthes speciosus (Dana), 1852. Petrolistltes 

 armatust (Gibbes), 1850, re-described by Miss Rathbun in 1910, 

 also makes a near approach to the present species.

The first of these references I borrow from Paulson, who does 

 not supply the date. The identification of Hilgendorf s species 

 I accept from Nobili. 



The carapace about as broad as long, with salient rostrum and 

 convergent lines of tubercles, as also the shape and armature of 

 the chelipeds, are in good agreement with Paulson's description 

 and figure of the species. The specimen is a female, and was 

 collected by Mr. K. H. Barnard.
