than the ramus, which is minute, little longer than broad, with a cleft apex carrying a

 some marginal setules, the ramus not longer than broad, scarcely appearing beyond the 

 peduncle, ending in upturned sharp teeth. - 



The Telson very short, not longer than broad, in a lateral view appearing to have the 

 apical border set round with two rows of sharp upturned teeth. 



Length. — The specimen, in the position figured, measured, from the rostrum to the 

 end of the first or second segment of the pleon, less than one-fifth of an inch. 



Locality. — The single specimen, a female, was obtained in Flinders Passage. 



Remark. — The specific name is taken from the place of capture.

For the orginal definition of the genus, see Note on Say, 1818 (p. 104). For the 

 definition of Glauconome, see Note on Kroyer, 1845 (p. 212). Unciata, Milne- 

 Edwards, 1838, is a mere misprint, and Cyrthophium, Danielssen, 1859, is only a 

 name, the identification of which with Glauconome rests upon Boeck's authority. Boeck 

 gives the following definition of the genus : — 



" Mandibles with three-jointed palp ; the third joint elongate, narrow, but shorter 

 than the second.
