38 CRUSTACEA FROM PORT CURTIS DISTRICT, QUEENSLAND, 



It has already been pointed out by Alcock* that the specific 

 name given by Miers had already been conferred by Filhol on a 

 New Zealand form. We have consequently pleasure in taking 

 this opportunity to dedicate it as above. 



It was originally described by Miers from a single specimen 

 taken in the Arafura Sea. From the material before us we are 

 able to supplement that author's description as follows : — 



The ophthalmic scale bears a distinct slender apical spine. The 

 larger cheliped has in addition to the "inner and upper" marginal 

 series of spinules, a granular series on the corresponding outer 

 margin commencing at the base of the wrist and continued on 

 the palm to the tip of the immobile finger. 



Family PORCELLANIDiE. 



Petrolisthes lamarcki (Leach). 



1898. Borradaile, Proc. Zool. Soc. London, p. 464, pl.xxxvi. 

 figs. 1 a-b, 2(with full synonymy). 



In view of the very thorough manner in which Borradaile has 

 dealt with this species, and of the large series of names which 

 he has put into synonymy, we have no hesitation in referring as 

 above to a large series of specimens dredged in 7 fathoms in Port 

 Curtis and taken on the reef on Mast Head Island. 



As a varietal feature it is noteworthy that the Port Curtis 

 specimens have the whole dorsal surface of a darkish purple 

 colour with deep red spots, and carry a scant tomentum, while 

 the specimens from the reef are much lighter and quite smooth.
