One of the chief distinguishing characters of this genus is the 3- 

 joiuted maxilliped. This has been well figured by Mrs. Sexton (I.e. 

 p. 241, figs. 7, 8). In fig. 6 Mrs. Sexton has figured an abnormal 

 maxilliped in which the terminal joint still shows a distinct suture, 

 so that there appear to be 4 joints in all. The present specimen 

 exhibits the same peculiarity, though as there is only the one specimen 

 it is impossible to say whether this is normal or not. But it shows 

 the danger, as pointed out by Mrs. Sexton, of dividing the family 

 into genera according to the number of joints in the maxillipeds when 

 only a limited amount of material is at hand. 



In this genus there is only one species which is at all thoroughly 

 known namely, A. gracilis Mont. A. flagellata Chiltou, 1882, from 

 New Zealand, agrees with graciUs in having a truncate telsou. Halio- 

 phasma maculata Haswell, 1881, from Australia, has been redescribed 

 by Chiltou in 1881 under the name of Anthura affinis. This species 

 has a linguiform telson and is closely allied to the species described
