DECAPOD CRUSTACEA FROM NORFOLK ISLAND. 



By the late F. E. Grant, F.L.S., axd Allan R. McCulloch, 

 Australian Museum. 



(Plate i.) 

 The small collection enumerated herein has reached us from 

 two sources. The first series was collected by Messrs. R. M. and 

 W. Laing, the latter a resident of the island, who placed them 

 in the hands of Prof. Chas. Chilton, of Christchurch, N.Z., and 

 who in turn very kindly forwarded them to us. For the others 

 we are indebted to Mr. A. Liddell, for whom they were collected 

 by Mr. J. Cornish Quintal. Our best thanks are due to both 

 our friends.

Eriphia norfolcensis, n.sp. (Plate i., figs.l, \a, \b). 

 Carapace almost | as long as broad, gastric and cardiac regions 

 faintly delimited. A well marked groove runs from each lateral 

 angle inwards and forwards in the direction of the orbits. Dorsal 

 surface smooth except on the hepatic regions, which carry a 

 number of subspiniform tubercles, and immediately behind the 

 front where it is granular. 



Front emarginate, lobes much deflexed, but their free edge, 

 which is well defined and granular, is visible from above. 



The inner orbital angles are separated from the front proper 

 by a shallow sulcus. 



Orbits entire, their upper borders granular, the lower minutely 

 spinulose.
