close together as possible. In both these rows the spines are set at right angles to 

 the joint, in the other rows they are arranged parallel to the length of the joint. 

 All these are essentially the same in character, but in the " parallel " series, the spines, 

 being viewed more laterally, appear to be curved and the blade forms a very 

 shallow scoop. 



The Legs are provided with longitudinal rows of curved spines, not very 

 numerous, especially on the ventral surface, most abundant and conspicuous on the 

 femur. The first coxa is conspicuously broader than the others. The lateral 

 processes of the body are narrow proximally and widen distally, the first coxa 

 continuing this widening. The two following coxse are of less diameter, sub-equal in 

 length, the distal extremity of each is fringed with minute spines, the fringe, 

 however, not being complete. The femur is conspicuously the longest joint of the 

 limb, the other joints progressively shorten, the amount of decrease being obvious. 

 The claw is nearly the length of the propodus. A few additional spines are to be 

 found ventrally at the distal extremity of some of the joints. 



The Genital apertures open on the second coxa of each leg. 



A single specimen of this species was taken off the Barrier in lat. 78° 25' 40" S., 

 long. 185° 39' 6" E., 300 fms., bottom, mud, 27 Jan. 1902. 



In the examination of this collection my thanks are primarily due to the Council 

 of the Marine Biological Association of the United Kingdom, and to Dr. E. J. Allen, 

 the Director, for accommodation at their Plymouth Laboratory ; to Professor Chilton, 

 of Canterbury College, Christchurch, N.Z., for enabling me to make the preliminary 

 examination of our collections ; to Mr. G. M. Thomson and Professor W. B. Benham, 

 of Dunedin, N.Z., for so kindly placing the whole of their collections at my disposal ; 

 to Professor E. L. Bouvier, of Paris, for allowing me to examine the collection made 

 by the ' Fran9ais ' in the Antarctic as well as the unpublished collections of the 

 ' Travailleur ' and ' Talisman ' ; to Professor Kraepelin, and particularly to Dr. G. 

 Pfefi"er, for the opportunity to examine the collection from South Georgia, now in 

 the Natural History Museum at Hamburg ; to Professor A. Brauer, and especially to 

 Dr. E. Vanhofien, biologist of the ' Gauss,' for the facilities extended to me during the 

 examination of the ' Valdivia ' and other collections now in the Berlin Museum. 



My best thanks are due to Mrs. L. E. Sexton for the drawings of Plates VI. 

 and IX., Plate II., Fig. 1., Plate V. (the entire animal). Plates X., Figs. 1-7, all of 

 which were executed with the greatest accuracy. I am further indebted to her for 

 some considerable assistance during the progress of the work. 



Messrs. West, Newman and Co. have continued the preparation of the plates, 

 and I must thank them for the care they have taken.
