I.—INTRODUCTION. 
The species of Decapoda obtained by the “Terra Nova” number 46 in all, and are 
distributed pretty evenly throughout the taxonomic divisions of the order. According 
to the localities in which they were taken, they fall into five groups : 
(1) Antarctic. 
(2) From New Zealand and the neighbouring waters. 
(3) From Melbourne Harbour (a single species). 
(4) From between Rio de Janeiro and South Trinidad Island. 
(5) Pelagic species from the tropical and sub-tropical Atlantic. 
(1) The Antarctic species were : 
Pasiphaea longispina , Lenz and Strunck, 1914. 
Chorismus antarcticus (Pfefter), 1887. 
Crctngon ( Notocrangon ) antarcticus, Pfeifer, 1887, var. gracilis , n. 
All were taken in the Ross Sea. 
* In sending to the press this paper and that which follows it, I wish to acknowledge very heartily 
the courtesy of the authorities of the British Museum (Natural History), who have afforded me facilities 
for doing at the Museum a good deal of the work which the examination of the “ Terra Nova’' collection 
has involved. In particular I am indebted to Dr. W. T. Caiman for the readiness with which he has 
placed at my disposal not only the collections under his charge, but also his own time and knowledge. 
Miss G. M. Woodward’s excellent illustrations owe much to the assistance which she has received 
from Dr. Caiman in their preparation.
