move slender; the seventh is very small; the eighth is scarcely 

 half the length of the sixth ; the claw is nearly two-thirds of the 

 length of the eighth joint. There is a whorl of hairs round the 

 distal end of each limb-process and a few scattered hairs on the 

 proximal joints ; there is- a small process at the distal ends of the 

 fourth, fifth, and sixth joints each bearing one long hair with 

 sometimes a small one at its base ; the seventh joint has a small 

 spine and three or four minute hairs on its ventral border ; the 

 eighth joint has a well-defined " sole," with a row of twelve (or 

 eleven) curved acute spines ; on the projection bounding the palm 

 are three other spines, one large, the others small ; between the 

 row of curved spines and the base of the claw is a row of very 

 minute hairs ; the second claw is only represented by a rudiment. 



The cement glands are placed in the fourth joint of the limbs, 

 and their common duct opens at the end of a very long haii'-like 

 process more than a third of the length of the joint itself. 



This species was obtained with the dredge in Port Jackson. 



Genus. PHOXICHILUS. Latreille. 



PlIOXICHILUS CIIARYBDiEUS. (?) Dohrn. 



I am unable to separate a species of Phoxichilus obtained at 

 Port Molle from the species above-named, which has hitherto only 

 been obtained in the Mediterranean, except that in my only 

 specimen the third appendages have only three joints instead of 

 seven as in Dohrn's species. This may be owing to the immaturity 

 of the specimen, and I have, therefore, refrained from adding 

 another specific name.
