36 CRUSTACEA PROM PORT CURTIS DISTRICT, QUEENSLAND, 



upper margin, a row of three smaller spines on its outer surface 

 near the lower margin, and a strong spine between these two 

 rows at its distal margin. The palm is half as long again as 

 broad; it carries four strong spines on its upper margin, and on 

 its outer surface two rows of spinulse terminating respectively in 

 the strong spine at the distal margin and in the lower row of 

 spines on the preceding joint. Its lower surface is granulous. 

 The immobile finger is somewhat deflexed, and the mobile finger 

 strongly arched; there is a wide opening between them when 

 closed. 



The right cheliped has three strong teeth on the upper margin 

 of the carpus, four somewhat smaller teeth on the upper margin 

 of the palm, and a row of small tubercles on its outer surface. 

 The mobile finger is serrulate on its upper margin and leaves a 

 strong gape when closed against the immobile finger. 



Both hands are clothed with stiff scattered hairs. 



The second and third legs are sparingly setose. They are sub- 

 cylindrical, and in length exceed the larger cheliped by the 

 dactylus and half the propodus. 



The fourth legs are subchelate, and the fifth pair distinctly 

 didactylous. 



Colour white, very faintly banded with red on the second and 

 third legs. 



Length of carapace 5mm. 



Two specimens were dredged off Mast Head Island, on a 

 bottom of coral sand. 



Troglopagurus jousseaumii Bouvier.

 Port Curtis; four specimens dredged in 7 fathoms; three of 

 these inhabited shells of Natica conica and one that of Purpura 

 pseudamygdala. In all cases the shells appeared to be too large 

 for their occupants, a peculiarity which, as Alcock has pointed 

 out, appears to be characteristic of the species.
