A small specimen was dredged off Mast Head Island in 20 

 fathoms. It measures 38mm. with the rostral cornuaand 25mm. 

 without. It differs from the description and figure only in 

 having the rostral cornua proportionately shorter and by having 

 all the spines knobbed instead of pointed ; these are undoubtedly 

 characters varying with age. 



The species was originally described from New Caledonia, and 

 the author states that there are specimens in the British Museum 

 from the New Hebrides. A fine specimen ($) measuring 

 117mm. in total length is in the Australian Museum from Lord 

 Howe Island, where it was found dead on the beach.

Mast Head Island; one specimen (£). 



This species is quoted by Haswell as of A. Milne Edwards, and 

 he gives P. gaimardii of Miers,* as a synonym. We have been 

 quite unable to trace the original description under the name of 

 sternocostulatus, and a reference to the Cat. N.Z. Crust, shows 

 gaimardii to be of H. Milne Edwardsf. It must consequently, 

 if it can be properly applied to our species, antedate the name 

 which we here quote. As, however, a diligent search has failed 

 to discover the missing reference, we are compelled to leave the 

 question of its correct nomenclature undecided.
