314: CRUSTACEA DREDGED OFF PORT JACKSON, 



There is a further strong horizontally directed spine on either 

 branchial region on the same line as the median spine on the 

 dorsum of the carapace. 



The basal antennal joint is broad, with its antero-external 

 angle produced. The flagella are visible from above outside 

 the rostral cornua. 



The chelipedes are only slightly more stout than the amVjula- 

 tory legs, and are of the same length as the carapace. The palms 

 and fingers are slender, the latter being finely toothed and with 

 a slight space between them at their bases when closed. 



The second pair of legs are considerably longer than the cheli- 

 pedes or than any of the three last pairs. The joints of all the 

 ambulatory legs are subcylindrical, and the dactyli are curved, 

 but without serrations on their inner margins. The basal joints 

 of the last pair are visible beyond the posterior margin of the 

 carapace on a dorsal view^ 



The merus of the external maxillipedes is shorter but con- 

 siderably broader than the ischium, and is expanded at its 

 antero-external angle. The short palp is carried at its antero- 

 internal angle. 



Dimensions of type {^) — 



From tip of rostrum to posterior margin 1 1 '0 mm. 



Breadth across branchial region 7*5 ,, 



Length of chelipedes 11*0 ,, 



Length of second pair of legs 15-0 ,, 



Six specimens were taken, of which two are males and four 

 females. All except two were much distorted through the 

 presence of a parasite of the family Bohyridce in the branchial 

 cavity. My knowledge of this group is, however, insufficient to 

 enable me to determine its generic position. 



All the specimens taken are of approximately the same size, 

 and there is little difference between the male and female 

 specimens. 



In the figure submitted the specimen is shown as denuded of 

 its pubescence — the medium of line work adopted not being 

 suitable for the adequate representation of such a surface.
